Meshtastic began with a straightforward goal: to keep hiking buddies connected in the outdoors when cell service was unavailable. What started as a simple project has grown, thanks to a passionate community pushing the boundaries of what's possible. Today, Meshtastic is used in Search and Rescue operations, off-grid communication, disaster recovery, and even grid-down scenarios. Whether it's preparing for the next flood or tornado, extending communication over the Internet with MQTT, or simply enjoying an off-grid adventure, Meshtastic has become an essential tool for many.

### Balancing Encryption with Practical Use
|
||||||
|
|
||||||
|
For many, Meshtastic's encryption is a key part of the appeal. Over the years, the challenge has been finding a balance: implementing strong encryption without excluding low-power IoT platforms or overwhelming LoRa's limited bandwidth. Before version 2.5, encryption relied on a static pre-shared key per channel, which was quite robust. However, it had one notable limitation: Direct Messages (DMs).
|
||||||
|
|
||||||
|
DMs were sent using the same shared channel key, which meant that while DMs were theoretically private, they were accessible to anyone on the same channel. The honor system was the only safeguard, particularly since the default Meshtastic setup uses a publicly known encryption key, leaving DMs effectively unencrypted out of the box.
|
||||||
|
|
||||||
|
### Challenges with Remote Administration
|
||||||
|
|
||||||
|
Remote administration also presented hurdles. The conventional method involved creating an "admin" channel, allowing any node on that channel to be controlled remotely. This approach had drawbacks, notably that nodes open to administering others were also vulnerable to being administered themselves.
|
||||||
|
|
||||||
|
## Introducing Public Key Cryptography (PKC) to Meshtastic
|
||||||
|
|
||||||
|
In 2022, a user named edinnen proposed a solution with a pull request that introduced a public/private key scheme for DMs. Although the initial feedback was promising, the patch became outdated as time passed. Recently, everything aligned, and we revisited and reworked this patch, making it the foundation of Meshtastic's version 2.5 development.
|
||||||
|
|
||||||
|
Our new PKC implementation is now a core feature, providing each node with a unique public key generated at first boot. This key enables secure, encrypted connections between nodes and serves as a unique identifier within the mesh. It also solves the remote administration challenge—nodes can now be identified and authorized as remote administrators through their public keys.
|
||||||
|
|
||||||
|
### A Major Step Forward in Security
|
||||||
|
|
||||||
|
With this new PKC scheme, Meshtastic offers enhanced encryption for DMs and secure remote administration for difficult-to-reach nodes. While we still caution against relying solely on Meshtastic encryption for life-or-death situations, this update marks a significant advancement in privacy and security for the mesh network.
|
||||||
|
|
||||||
|
### Technical Deep Dive: The Mechanics of Meshtastic's New Encryption
|
||||||
|
|
||||||
|
At the heart of Meshtastic's new encryption system lies the X25519 elliptic curve Diffie-Hellman key exchange. This process unfolds in two key steps:
|
||||||
|
|
||||||
|
1. Key Generation: Upon first boot, each device generates a random private key and derives a corresponding public key using the X25519 algorithm. This public key is then broadcast to the mesh as part of the node's regular announcements.
|
||||||
|
|
||||||
|
2. Secure Communication: When a node initiates a Direct Message (DM), it completes the X25519 key exchange by combining its private key with the recipient's public key. This process generates a unique shared secret, which is then used to encrypt the DM. The receiving node can independently derive the same shared secret using its private key and the sender's public key, enabling secure decryption.
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
The encryption scheme employs AES-CCM (Counter with CBC-MAC), which provides both confidentiality and authenticity. A notable feature is the inclusion of a short Message Authentication Code, verifying the sender's identity and ensuring message integrity. To further enhance security, DM messages incorporate an additional 4 bytes of random nonce, effectively preventing potential compromises due to nonce reuse.
|
||||||
|
|
||||||
|
Remote administration has also seen significant improvements. Administration messages now include an 8-byte session key, set by the node being administered. This key is included in responses and must be present in any packet attempting to make changes. With a 300-second timeout, this mechanism provides robust protection against replay attacks of captured administration traffic.
|
||||||
|
|
||||||
|
## Conclusion
|
||||||
|
|
||||||
|
Meshtastic's journey from a simple hiking communication tool to a versatile, secure mesh networking solution showcases the power of community-driven development. The introduction of our new Public Key Cryptography scheme in version 2.5 represents a significant advancement in the platform's security capabilities, addressing long-standing challenges in direct messaging and remote administration.
|
||||||
|
|
||||||
|
As we continue to refine and expand Meshtastic's features, we remain committed to balancing robust security with practical usability. While this update significantly enhances the platform's privacy and security, we encourage users to approach encryption with a clear understanding of its strengths and limitations, especially in critical scenarios.
|
||||||
|
|
||||||
|
Looking ahead, we're excited about the possibilities this new encryption framework opens up. We invite our community to explore these new features, provide feedback, and continue pushing the boundaries of what's possible with Meshtastic. Together, we're building a more secure and connected future for off-grid communication.

description: "Understand Meshtastic's encryption: optional network-wide AES256 security for off-grid communication, ensuring confidentiality against passive eavesdropping."
|
|
||||||
---
|
|
||||||
|
|
||||||
## Explanation
|
|
||||||
|
|
||||||
Meshtastic provides AES256-CTR encryption for the payload of each packet when sending via LoRa, with a different key for each [channel](/docs/configuration/radio/channels/). The [packet header](/docs/overview/mesh-algo/#layer-1-unreliable-zero-hop-messaging) is always sent unencrypted, which allows nodes to relay packets they can't decrypt as well. One can disable this by setting a different [rebroadcast mode](/docs/configuration/radio/device#rebroadcast-mode).
|
|
||||||
|
|
||||||
By default you have one primary channel which is encrypted with a simple known key ("AQ=="), so to use proper encryption you **must change** this key first, or create a new channel and share it with the ones you want to communicate with. However, if you don't have the default key, it means you will not be able to communicate with devices that don't have your key.
|
|
||||||
|
|
||||||
Direct messages to a specific node (e.g. text, traceroute or position requests) may use any channel you share with the recipient. Namely, the device will use the one where it most recently heard a NodeInfo packet from the recipient on. Client apps will not show messages directed to other nodes, but in principle they could be read by **anyone** who knows the used channel key. This means that if it uses the default key, you have to assume anyone could read your direct messages.
|
|
||||||
|
|
||||||
All periodic broadcasts (position, telemetry, etc.) the device sends out itself are sent over the primary channel and thus encrypted with that key.
|
|
||||||
|
|
||||||
The device will decrypt the payload before sending it to a client app via BLE, serial, Wi-Fi/Ethernet. For MQTT you can [specify](/docs/configuration/module/mqtt#encryption-enabled) whether you want to send an encrypted or unencrypted payload.
|
|
||||||
|
|
||||||
## Is it as secure as Wi-Fi WPA3, HTTPS TLS1.3 or Signal ?
|
|
||||||
|
|
||||||
**No**.
|
|
||||||
|
|
||||||
[WPA3](https://en.wikipedia.org/wiki/WPA3), [TLS1.3](https://en.wikipedia.org/wiki/TLS1.3), [Signal](https://en.wikipedia.org/wiki/Signal_Protocol) and Meshtastic can all use AES256, yet AES is one of the many cogs required in a modern encryption system, see below the main features "missing" in Meshtastic.
|
|
||||||
|
|
||||||
### Perfect-Forward-Secrecy
|
|
||||||
|
|
||||||
[**P**erfect-**F**orward-**S**ecrecy also known as **PFS**](https://en.wikipedia.org/wiki/Forward_secrecy) means *previous* communications and more generally anything *passively captured* cannot be decrypted ***even when the key is compromised***.
|
|
||||||
|
|
||||||
This means Meshtastic is vulnerable to [**« Harvest now, Decrypt later »**](https://en.wikipedia.org/wiki/Harvest_now,_decrypt_later) attacks, **this attack itself is not enough to decrypt messages** it relies on an other failure leaking the channel key such as:
|
|
||||||
- Accidently sharing the channel key with the wrong person.
|
|
||||||
- One of your nodes being stolen.
|
|
||||||
- Any unknown bug revealing the channel key to an attacker.
|
|
||||||
|
|
||||||
Other protocols such as *misconfigured TLS1.2* are far more impacted by Harvest now, Decrypt later attacks because their keys will be broken by near future Quantum-Computers yet they do not provide PFS.
|
|
||||||
|
|
||||||
Meshtastic's encryption is not threatened by Quantum-Computers\* so realistic attack vectors are accidental miss-handling of channel keys and nodes being lost.
|
|
||||||
|
|
||||||
\*on the Quantum-Resistance of AES256 see:
|
|
||||||
- [this stackoverflow question, contain a bit of debates and two good answers](https://crypto.stackexchange.com/q/6712)
|
|
||||||
- [NIST's Post-Quantum FAQ](https://csrc.nist.gov/projects/post-quantum-cryptography/faqs) section « To protect against the threat of quantum computers, should we double the key length for AES now? (added 11/18/18) »
|
|
||||||
|
|
||||||
**Recommendations** for users using *private channels*:
|
|
||||||
- **Do not configure private channels on unattended nodes**, nodes will relay meshtastic traffic even if they are not able to decrypt it.
|
|
||||||
Your unattended routers should not have the private PSK configured as it is easy to gain physical access and extract the channel key.
|
|
||||||
- Keep in mind, everything sent on a channel can be stored and decrypted later by anyone who gain access to the key even if you locally delete the messages.
|
|
||||||
- Change your Channel Keys from time to time.
|
|
||||||
|
|
||||||
### Integrity
|
|
||||||
|
|
||||||
Integrity means ensuring messages cannot be modified without the key.
|
|
||||||
|
|
||||||
Meshtastic does not check messages have not been tempered with, see [`#4030`](https://github.com/meshtastic/firmware/issues/4030) for details.
|
|
||||||
|
|
||||||
**Recommendations**:
|
|
||||||
- Keep in mind, by applying a known plaintext attack anyone *could* send messages on a channel even with the channel key is private and secure.
|
|
||||||
- For developers of third party applications integrating meshtastic, include a cryptographic MAC over the message content and PSK,
|
|
||||||
we are also considering an [AEAD secured channel mode which would provide this natively](https://github.com/meshtastic/firmware/issues/4030).
|
|
||||||
|
|
||||||
### Authentication
|
|
||||||
|
|
||||||
Authentication means nodes say who they are on the network, meshtastic does not implement this so it is trivial to impersonate anyone else if you have access to the channel key.
|
|
||||||
|
|
||||||
This is because node ids are based on hardware [MAC address](https://en.wikipedia.org/wiki/MAC_address), theses are hardcoded by the manufacturer.
|
|
||||||
|
|
||||||
Some other networks like [Yggdrasil](https://yggdrasil-network.github.io/), [cjdns](https://github.com/cjdelisle/cjdns) or [libp2p](https://libp2p.io/) use [public / private key pairs](https://en.wikipedia.org/wiki/Public-key_cryptography) and the Public Key becomes the Node Identity, this make all messages bigger and or require an interactive handshake process.
|
|
||||||
|
|
||||||
**Recommendations**:
|
|
||||||
- Keep in mind, the sender field is indicative and anyone with access to the channel key can trivially lie.
|
|
||||||
|
|
||||||
## Direct-Messages
|
|
||||||
|
|
||||||
Direct-Messages are implemented as channel messages which have a `to` protobuf field set.
|
|
||||||
|
|
||||||
This means anyone in the channel can read all your direct-messages.
|
|
||||||
|
|
||||||
Also the node needs to know the right channel to use, this is done by using the latest one a NodeInfo was received, due to the lack of `Authentication` this means anyone you share a channel with can send a spoofed NodeInfo and make you send direct-messages on an incorrect public channel.
|
|
||||||
|
|
||||||
**Recommendations**:
|
|
||||||
- Keep in mind, due to NodeInfo spoof issue Direct-Messages are **very significantly less secure than a private channel** with a secure PSK.
|
|
||||||
- Do not use Direct-Messages for anything private, instead ahead of time create a new private channel and share it with the person you want to message with.
|
|
||||||
- Nodes will relay encrypted packets even if they can't decrypt it, so you only loose on some [small DM optimizations](https://github.com/meshtastic/firmware/pull/3753).
|
|
||||||
- Do not send the private channel key in direct messages or a public channel, because then anyone listening gain access.
|
|
||||||
- Use a different private channel for each person you want to have private conversations with.
|
|
||||||
|
|
||||||
## Comments
|
|
||||||
|
|
||||||
Cryptography is tricky, so we've tried to 'simply' apply standard crypto solutions to our implementation. However, the project developers are not cryptography experts.
|
|
||||||
|
|
||||||
Based on comments from reviewers (see below), here are some tips for usage of these radios, so that you may know the level of protection offered:
|
|
||||||
|
|
||||||
- It is pretty likely that the AES256 security is implemented 'correctly' and an observer will not be able to decode your messages.
|
|
||||||
- Warning: If an attacker is able to get one of the radios in their possession, they could either a) extract the channel key from that device or b) use that radio to listen to new communications.
|
|
||||||
- Warning: If an attacker is able to get the "Channel QR code/URL" that you share with others - that attacker could then be able to read any messages sent on the channel (either tomorrow or in the past - if they kept a raw copy of those broadcast packets)
|
|
||||||
|
|
||||||
The current implementation provides optional confidentiality to members of a configured network:
|
|
||||||
|
|
||||||
- Encryption is implemented in devices/nodes with network-wide encryption keys.
|
|
||||||
- Encryption is optional and is turned off when devices are in 'Ham mode'.
|
|
||||||
- There is no encryption supported in the clients (iOS, Android) to facilitate distribution as mass market software.
|
|
||||||
- Pairing from client-to-device is by:
|
|
||||||
- direct USB cable
|
|
||||||
- BT pairing
|
|
||||||
- Devices are 'promiscuous' and will pair with any near-by client. Network confidentiality requires physical protection of all nodes.
|
|
||||||
|
|
||||||
Always keep in mind [xkcd's note on encryption](https://xkcd.com/538).
|
|
||||||
|
|
||||||
|
|
||||||
- If you are a cryptography expert, please review these notes and our questions below. Can you help us by reviewing our notes below and offering advice? We will happily give as much or as little credit as you wish ;-).
|
|
||||||
- Consider our existing solution 'alpha' and probably fairly secure against a not particularly aggressive adversary (but we can't yet make a more confident statement).
|
|
||||||
|
|
||||||
|
|
||||||
### Notes for reviewers
|
|
||||||
|
|
||||||
If you are reviewing our implementation, this is a brief statement of our method.
|
|
||||||
|
|
||||||
- We do all crypto at the SubPacket (payload) level only, so that all Meshtastic nodes will route for others - even those channels which are encrypted with a different key.
|
|
||||||
- Mostly based on reading [Wikipedia](<https://en.wikipedia.org/wiki/Block_cipher_mode_of_operation#Counter_(CTR)>) and using the modes the ESP32 provides support for in hardware.
|
|
||||||
- We use AES256-CTR as a stream cypher (with zero padding on the last BLOCK) because it is well supported with hardware acceleration.
|
|
||||||
- Our AES key is 128 or 256 bits, shared as part of the 'Channel' specification.
|
|
||||||
- The node number concatenated with the packet number is used as the NONCE. This nonce will be stored in flash in the device and should essentially never repeat. If the user makes a new 'Channel' (i.e. picking a new random 256 bit key), the packet number will start at zero.
|
|
||||||
- The packet number is sent in cleartext with each packet. The node number can be derived from the "from" field of each packet. (Cleartext is acceptable because it merely provides IV for each encryption run)
|
|
||||||
- Each 16 byte BLOCK for a packet has an incrementing COUNTER. COUNTER starts at zero for the first block of each packet.
|
|
||||||
- The IV for each block is constructed by concatenating the NONCE as the upper 96 bits of the IV and the COUNTER as the bottom 32 bits. Since our packets are small counter portion will really never be higher than 32 (five bits).
|
|
||||||
|
|
||||||
### Comments from reviewer #1
|
|
||||||
|
|
||||||
This reviewer is a cryptography professional, but would like to remain anonymous. We thank them for their comments ;-):
|
|
||||||
|
|
||||||
I'm assuming that meshtastic is being used to hike in places where someone capable is trying to break it - like you were going to walk around DefCon using these. I spent about an hour reviewing the encryption, and have the following notes:
|
|
||||||
|
|
||||||
- The write-up isn't quite as clear as the code.
|
|
||||||
- The code is using AES-CTR mode correctly to ensure confidentiality.
|
|
||||||
- The comment for initNonce really covers the necessary information.
|
|
||||||
- I think the bigger encryption question is "what does the encryption need to do"? As it stands, an attacker who has yet to capture any of the devices cannot reasonably capture text or location data. An attacker who captures any device in the channel/mesh can read everything going to that device, everything stored on that device, and any other communication within the channel that they captured in encrypted form. If that capability basically matches your expectations, it is suitable for whatever adventures this was intended for, then, based on information publicly available or widely disclosed, the encryption is good. If those properties are distressing (like, device history is deliberately limited and you don't want a device captured today to endanger the information sent over the channel yesterday) we could talk about ways to achieve that (most likely synchronizing time and replacing the key with its own SHA256 every X hours, and ensuring the old key is not retained unnecessarily).
|
|
||||||
- Two other things to keep in mind are that AES-CTR does not itself provide authenticity (e.g. an attacker can flip bits in replaying data and scramble the resulting plaintext), and that the current scheme gives some hints about transmission in the size. So, if you worry about an adversary deliberately messing-up messages or knowing the length of a text message, it looks like those might be possible.
|
|
||||||
|
|
||||||
I'm guessing that the network behaves somewhat like a store-and-forward network - or, at least, that the goal is to avoid establishing a two-way connection to transmit data. I'm afraid I haven't worked with mesh networks much, but remember studying them briefly in school about ten years ago.

- The IV initialization only use 31 random bits per reboot, it then increment messages sequentially. This is not high, it makes duplicate unlikely but probable given the complete scale of the network. Thankfully IV include lower 32 bits of the MAC address which should be unique per node, so each node is it's own birthday paradox, we aren't looking for network wide birthday paradox which would be easy to hack. See [`#4031`](https://github.com/meshtastic/firmware/issues/4031).

Could be fixed.
|
|
||||||
- The lack of [integrity wasn't properly considered](https://github.com/meshtastic/firmware/issues/4030), the remote administration module implements priviliged RPC calls over AES-CTR without any MAC or AEAD.
|
|

Could be fixed.
|
|
||||||
- The AES-CTR implementation looks like it protects Confidentiality assuming IVs are not duplicated.
|
|
||||||
- The lack of Forward Secrecy is a bit worrying for a chat messenger when new users lack the paranoid and annoying key management practice that would be required for safe operation.
|
|
||||||
- IMO the clients should have a big red box the first time you open a Direct-Message indicating theses are not private and not E2E. This was not clear to me without reading the code.
|
|
||||||
- This project is completely fine for chatting with strangers, using the default key and understanding everything is public, I would not trust it with anything private without some other layer or significant reworks. For example I would consider SSH or Signal over Meshtastic safe. Yet Meshtastic does not choose to have worse crypto for bad reasons, they make the network significantly more usable over the unreliable slow LoRa backhaul it is using.

This page compiles community feedback and expert reviews on Meshtastic's encryption approach. We value these insights and aim to improve our encryption implementation where feasible. Explore key details, practical tips, and understand the strengths and potential limitations of Meshtastic's AES256 encryption.

## Comments
|
||||||
|
|
||||||
|
Cryptography is tricky, so we've tried to 'simply' apply standard crypto solutions to our implementation. However, the project developers are not cryptography experts.
|
||||||
|
|
||||||
|
Based on comments from reviewers (see below), here are some tips for using these radios, so that you may know the level of protection offered:
|
||||||
|
|
||||||
|
- It is likely that the AES256 security is implemented 'correctly' and an observer will not be able to decode your messages.
|
||||||
|
- **Warning:** If an attacker is able to get one of the radios in their possession, they could either a) extract the channel key from that device, or b) use that radio to listen to new communications.
|
||||||
|
- **Warning:** If an attacker is able to get the "Channel QR code/URL" that you share with others, that attacker could then be able to read any messages sent on the channel (either tomorrow or in the past - if they kept a raw copy of those broadcast packets).
|
||||||
|
|
||||||
|
The current implementation provides optional confidentiality to members of a configured network:
|
||||||
|
|
||||||
|
- Encryption is implemented in devices/nodes with network-wide encryption keys.
|
||||||
|
- Encryption is optional and is turned off when devices are in 'Ham mode'.
|
||||||
|
- There is no encryption supported in the clients (iOS, Android) to facilitate distribution as mass-market software.
|
||||||
|
- Pairing from client-to-device is by:
|
||||||
|
- Direct USB cable
|
||||||
|
- BT pairing
|
||||||
|
- Devices are 'promiscuous' and will pair with any nearby client. Network confidentiality requires physical protection of all nodes.
|
||||||
|
|
||||||
|
Always keep in mind [xkcd's note on encryption](https://xkcd.com/538).
|
||||||
|
|
||||||
|
- If you are a cryptography expert, please review these notes and our questions below. Can you help us by reviewing our notes below and offering advice? We will happily give as much or as little credit as you wish ;-).
|
||||||
|
- Consider our existing solution 'alpha' and probably fairly secure against a not particularly aggressive adversary (but we can't yet make a more confident statement).
|
||||||
|
|
||||||
|
## Notes for reviewers
|
||||||
|
|
||||||
|
If you are reviewing our implementation, this is a brief statement of our method.
|
||||||
|
|
||||||
|
- We do all crypto at the SubPacket (payload) level only, so that all Meshtastic nodes will route for others - even those channels which are encrypted with a different key.
|
||||||
|
- Mostly based on reading [Wikipedia](<https://en.wikipedia.org/wiki/Block_cipher_mode_of_operation#Counter_(CTR)>) and using the modes the ESP32 provides support for in hardware.
|
||||||
|
- We use AES256-CTR as a stream cypher (with zero padding on the last BLOCK) because it is well supported with hardware acceleration.
|
||||||
|
- Our AES key is 128 or 256 bits, shared as part of the 'Channel' specification.
|
||||||
|
- The node number concatenated with the packet number is used as the NONCE. This nonce will be stored in flash in the device and should essentially never repeat. If the user makes a new 'Channel' (i.e. picking a new random 256 bit key), the packet number will start at zero.
|
||||||
|
- The packet number is sent in cleartext with each packet. The node number can be derived from the "from" field of each packet. (Cleartext is acceptable because it merely provides IV for each encryption run)
|
||||||
|
- Each 16 byte BLOCK for a packet has an incrementing COUNTER. COUNTER starts at zero for the first block of each packet.
|
||||||
|
- The IV for each block is constructed by concatenating the NONCE as the upper 96 bits of the IV and the COUNTER as the bottom 32 bits. Since our packets are small counter portion will really never be higher than 32 (five bits).
|
||||||

### Comments from reviewer #1

|
||||||
|
This reviewer is a cryptography professional, but would like to remain anonymous. We thank them for their comments ;-):
|
||||||
|
|
||||||
|
I'm assuming that meshtastic is being used to hike in places where someone capable is trying to break it - like you were going to walk around DefCon using these. I spent about an hour reviewing the encryption, and have the following notes:
|
||||||
|
|
||||||
|
- The write-up isn't quite as clear as the code.
|
||||||
|
- The code is using AES-CTR mode correctly to ensure confidentiality.
|
||||||
|
- The comment for initNonce really covers the necessary information.
|
||||||
|
- I think the bigger encryption question is "what does the encryption need to do"? As it stands, an attacker who has yet to capture any of the devices cannot reasonably capture text or location data. An attacker who captures any device in the channel/mesh can read everything going to that device, everything stored on that device, and any other communication within the channel that they captured in encrypted form. If that capability basically matches your expectations, it is suitable for whatever adventures this was intended for, then, based on information publicly available or widely disclosed, the encryption is good.

description: "Understand Meshtastic's encryption: optional network-wide AES256 security for off-grid communication, ensuring confidentiality against passive eavesdropping."
|
||||||
|
---
|
||||||
|
|
||||||
|
## Explanation
|
||||||
|
|
||||||
|
Meshtastic provides AES256-CTR encryption for the payload of each packet when sending via LoRa, with a different key for each [channel](/docs/configuration/radio/channels/). The [packet header](/docs/overview/mesh-algo/#layer-1-unreliable-zero-hop-messaging) is always sent unencrypted, which allows nodes to relay packets they can't decrypt as well. One can disable this by setting a different [rebroadcast mode](/docs/configuration/radio/device#rebroadcast-mode).
|
||||||
|
|
||||||
|
By default, you have one primary channel, which is encrypted with a simple known key ("AQ=="), so to use proper encryption, you **must change** this key first, or create a new channel and share it with the ones you want to communicate with. However, if you don't have the default key, it means you will not be able to communicate with devices that don't have your key.
|
||||||
|
|
||||||
|
Direct messages to a specific node are now encrypted using Public Key Cryptography (PKC). Each node is equipped with a unique public/private key pair, and direct messages are encrypted with the recipient's public key. This ensures that only the recipient can decrypt the message using their private key. Additionally, messages are signed with the sender's private key, allowing the recipient to verify the sender's identity and ensuring the message's integrity.
|
||||||
|
|
||||||
|
All periodic broadcasts (position, telemetry, traceroutes, etc.) the device sends out itself are sent over the primary channel and thus encrypted with that key.
|
||||||
|
|
||||||
|
The device will decrypt the payload before sending it to a client app via BLE, serial, Wi-Fi/Ethernet. For MQTT, you can [specify](/docs/configuration/module/mqtt#encryption-enabled) whether you want to send an encrypted or unencrypted payload.
|
||||||
|
|
||||||
|
## Is it as secure as Wi-Fi WPA3, HTTPS TLS1.3, or Signal?
|
||||||
|
|
||||||
|
**No**.
|
||||||
|
|
||||||
|
[WPA3](https://en.wikipedia.org/wiki/WPA3), [TLS1.3](https://en.wikipedia.org/wiki/TLS1.3), [Signal](https://en.wikipedia.org/wiki/Signal_Protocol), and Meshtastic can all use AES256. Yet AES is one of the many cogs required in a modern encryption system. Below are the main features "missing" in Meshtastic.
|
||||||
|
|
||||||
|
### Perfect-Forward-Secrecy
|
||||||
|
|
||||||
|
[**P**erfect-**F**orward-**S**ecrecy, also known as **PFS**](https://en.wikipedia.org/wiki/Forward_secrecy), means _previous_ communications and more generally anything _passively captured_ cannot be decrypted **_even when the key is compromised_**.
|
||||||
|
|
||||||
|
This means Meshtastic is vulnerable to [**« Harvest now, Decrypt later »**](https://en.wikipedia.org/wiki/Harvest_now,_decrypt_later) attacks. **This attack itself is not enough to decrypt messages**; it relies on another failure leaking the channel key, such as:
|
||||||
|
|
||||||
|
- Accidentally sharing the channel key with the wrong person.
|
||||||
|
- One of your nodes being stolen.
|
||||||
|
- Any unknown bug revealing the channel key to an attacker.
|
||||||
|
|
||||||
|
Other protocols, such as _misconfigured TLS1.2_, are far more impacted by Harvest now, Decrypt later attacks because their keys will be broken by near-future Quantum-Computers, yet they do not provide PFS.
|
||||||
|
|
||||||
|
Meshtastic's AES256 encryption is considered quantum-resistant[^1], but the public/private key exchange for DMs is not, as current quantum-resistant cryptography schemes don't fit in LoRa packets or our IoT hardware; realistic attack vectors include accidental mishandling of channel keys, nodes being lost, and potential future quantum attacks on DM key exchanges.
|
||||||
|
|
||||||
|
[^1]: On the Quantum-Resistance of AES256, see [this stackoverflow question, containing a bit of debate and two good answers](https://crypto.stackexchange.com/q/6712) and the [NIST's Post-Quantum FAQ](https://csrc.nist.gov/projects/post-quantum-cryptography/faqs) section "To protect against the threat of quantum computers, should we double the key length for AES now? (added 11/18/18)"
|
||||||
|
|
||||||
|
#### Recommendations for users using private channels
|
||||||
|
|
||||||
|
- **Do not configure private channels on unattended nodes**. Nodes will relay Meshtastic traffic even if they are not able to decrypt it. Your unattended routers should not have the private PSK configured as it is easy to gain physical access and extract the channel key.
|
||||||
|
- Keep in mind that everything sent on a channel can be stored and decrypted later by anyone who gains access to the key, even if you locally delete the messages.
|
||||||
|
- Change your Channel Keys from time to time.
|
||||||
|
|
||||||
|
#### Changes since 2.5.0 Firmware release
|
||||||
|
|
||||||
|
- Direct Messages are now protected with PKC when messaging between devices on v2.5.0 or newer and key exchange has taken place, messaging to legacy 2.4.3 or older firmware versions are not protected.
|
||||||
|
- Admin Messages between two v2.5.0 or newer nodes are now protected and additonal relay attack protection in place.
|
||||||
|
|
||||||
|
### Integrity
|
||||||
|
|
||||||
|
Integrity means ensuring messages cannot be modified without the key.
|
||||||
|
|
||||||
|
Meshtastic does not verify the integrity of channel messages to check if they have been tampered with (see [issue #4030](https://github.com/meshtastic/firmware/issues/4030) for details).
|
||||||
|
|
||||||
|
#### Recommendations
|
||||||
|
|
||||||
|
- Keep in mind that by applying a known plaintext attack, anyone _could_ send messages on a channel even if the channel key is private and secure.
|
||||||
|
- For developers of third-party applications integrating Meshtastic, include a cryptographic MAC over the message content and PSK. We are also considering an [AEAD secured channel mode which would provide this natively](https://github.com/meshtastic/firmware/issues/4030).
|
||||||
|
|
||||||
|
#### Changes since 2.5.0 Firmware release
|
||||||
|
|
||||||
|
- Message integrity is checked for Direct Messages or Admin Control when communication is between v2.5.0 or newer firmware.
|
||||||
|
|
||||||
|
### Authentication
|
||||||
|
|
||||||
|
Authentication means nodes say who they are on the network. Meshtastic does not implement this, so it is trivial to impersonate anyone else if you have access to the channel key
|
||||||
|
|
||||||
|
This is because node IDs are based on hardware [MAC address](https://en.wikipedia.org/wiki/MAC_address), which are hardcoded by the manufacturer.
|
||||||
|
|
||||||
|
Some other networks like [Yggdrasil](https://yggdrasil-network.github.io/), [cjdns](https://github.com/cjdelisle/cjdns), or [libp2p](https://libp2p.io/) use [public/private key pairs](https://en.wikipedia.org/wiki/Public-key_cryptography), and the Public Key becomes the Node Identity. This makes all messages bigger and/or requires an interactive handshake process.
|
||||||
|
|
||||||
|
#### Recommendations
|
||||||
|
|
||||||
|
- Keep in mind that the sender field is indicative, and anyone with access to the channel key can trivially lie.
|
||||||
|
|
||||||
|
#### Changes since 2.5.0 Firmware release
|
||||||
|
|
||||||
|
- The above now only relates to group chats/channels as DM's are protected when messaging between devices on 2.5 or newer, messaging to legacy 2.4 or older devices are not afforded this addition authentication.
|
||||||
|
|
||||||
|
## Direct Messages
|
||||||
|
|
||||||
|
Direct Messages (DMs) are now implemented using Public Key Cryptography (PKC). This provides a significant upgrade in security compared to the previous channel-based encryption:
|
||||||
|
|
||||||
|
- **Message Encryption:** Each DM is encrypted using the recipient's public key, ensuring that only the recipient can decrypt the message with their private key.
|
||||||
|
- **Digital Signatures:** Messages are signed with the sender's private key, allowing the recipient to verify the sender's identity and ensuring the integrity of the message.
|
||||||
|
|
||||||
|
### Prior to 2.5.0 Firmware Release
|
||||||
|
|
||||||
|
Previously, DMs were implemented as channel messages with a `to` protobuf field set. This meant anyone in the channel could read all your direct messages. With PKC, this issue is resolved, as only the intended recipient can decrypt and read the message.
|
||||||
|
|
||||||
|
### Recommendations
|
||||||
|
|
||||||
|
- While PKC significantly enhances the security of DMs, it's still advisable to avoid sharing sensitive information in direct messages without proper verification of the recipient's public key.
|
||||||
|
|
||||||
|
## Admin Messages
|
||||||
|
|
||||||
|
Admin Messages/Control are now protected by enhanced security features, making sure that critical operations within the network are more secure than ever before.
|
||||||
|
|
||||||
|
- **Stronger Encryption:** Admin Messages now use advanced encryption methods to ensure that only the intended recipients can access and read them.
|
||||||
|
- **Session IDs:** Each administrative session is assigned a unique Session ID, which helps prevent unauthorized access and ensures that messages are not tampered with or replayed.
|
||||||
|
|
||||||
|
### Prior to 2.5.0 Firmware Release
|
||||||
|
|
||||||
|
Previously, admin messages were not as secure, but with these updates, they are now much better protected against potential attacks and replay attacks.
|
||||||
|
|
||||||
|
### Recommendations
|
||||||
|
|
||||||
|
- Always ensure that your devices are using the latest firmware to benefit from these improved security features.
|
||||||
|
- Regularly monitor your network for any unusual activity to maintain a high level of security.

### OK to MQTT
|
||||||
|
|
||||||
|
Acceptable values: `true`, `false`
|
||||||
|
|
||||||
|
Default is `false`. When set to `true`, this configuration indicates that the user approves the packet to be uploaded to MQTT. If set to `false`, remote nodes are requested not to forward packets to MQTT.
|
||||||
|
|
||||||
|
**Important:** This is not a cryptographic solution but a polite request that is enforced in the official firmware.

The security config options are: Public Key, Private Key, Admin Key, Is Managed, Serial Console, Debug Logs, and Admin Channel.
|
||||||
|
|
||||||
|
## Security Config Values
|
||||||
|
|
||||||
|
### Public Key
|
||||||
|
|
||||||
|
Acceptable values: `bytes`
|
||||||
|
|
||||||
|
The public key of the device, shared with other nodes on the mesh to allow them to compute a shared secret key for secure communication.
|
||||||
|
|
||||||
|
### Private Key
|
||||||
|
|
||||||
|
Acceptable values: `bytes`
|
||||||
|
|
||||||
|
The private key of the device, used to create a shared key with a remote device for secure communication.**This key should be kept confidential.**
|
||||||
|
|
||||||
|
### Admin Key
|
||||||
|
|
||||||
|
Acceptable values: `repeated bytes`
|
||||||
|
|
||||||
|
The public key(s) authorized to send administrative messages to this node. Only messages signed by these keys will be accepted for administrative control.
|
||||||
|
|
||||||
|
### Managed Mode
|
||||||
|
|
||||||
|
Acceptable values: `true` or `false`
|
||||||
|
|
||||||
|
Enabling Managed Mode restricts access to all radio configurations via client applications. Radio configurations will only be accessible through the Admin channel. Ensure the Admin channel is functioning properly before enabling this mode to avoid being locked out.
|
||||||
|
|
||||||
|
### Serial Console
|
||||||
|
|
||||||
|
Acceptable values: `true` or `false`
|
||||||
|
|
||||||
|
Disabling this will prevent the Serial Console from initializing the Stream API.
|
||||||
|
|
||||||
|
### Debug Log
|
||||||
|
|
||||||
|
Acceptable values: `true` or `false`
|
||||||
|
|
||||||
|
By default, logging is disabled when an API client connects to keep the shared serial link quiet. Set this to true to continue outputting live debug logs over serial or Bluetooth when the API is active.
|
||||||
|
|
||||||
|
### Admin Channel Enabled
|
||||||
|
|
||||||
|
Acceptable values: `true` or `false`
|
||||||
|
|
||||||
|
Allows incoming device control over the insecure legacy admin channel. Enabling this option permits control messages to be received through the older, less secure admin channel.

|
||||||
|
|
||||||
|
## PSK for Channels, PKC for Direct Messages (DMs) and Admin Messages
|
||||||
|
|
||||||
|
Starting with firmware version 2.5.0, which introduces Public Key Cryptography (PKC) for Direct Messages (DMs) and additionally incorporating the use of Session IDs for Admin Messages, the security architecture of Meshtastic has reached a new level of robustness.
|
||||||
|
|
||||||
|
Below is a detailed overview of how PSK, PKC, and Session IDs are integrated into your system to secure Channels, Direct Messages, and Admin Messages.
|
||||||
|
|
||||||
|
### 1. Chat Channels Using Pre-Shared Key (PSK)
|
||||||
|
|
||||||
|
- **PSK Overview:**
|
||||||
|
|
||||||
|
- Chat Channels continue to utilize a Pre-Shared Key (PSK) for encrypting communications.
|
||||||
|
- All participants share the same PSK for their Channels, which is used for both encryption and decryption within the channel.
|
||||||
|
|
||||||
|
- **Security Considerations:**
|
||||||
|
- **Confidentiality:** Only participants with the correct PSK can access messages within the Chat Channel.
|
||||||
|
- **Key Management:** Secure distribution and regular rotation of the PSK are essential to maintaining the channel's security.
|
||||||
|
|
||||||
|
### 2. Direct Messages (DMs) Now Using PKC
|
||||||
|
|
||||||
|
- **PKC Implementation for DMs:**
|
||||||
|
|
||||||
|
- **Public/Private Key Pairs:** Each node is equipped with a unique public/private key pair. The private key is securely stored on the node, and the public key is shared with other nodes, allowing for secure, authenticated communication.
|
||||||
|
- **Encryption and Signature:**
|
||||||
|
- **Encryption:** DMs are encrypted using the recipient’s public key, ensuring only the recipient with the corresponding private key can decrypt the message.
|
||||||
|
- **Digital Signatures:** Messages are signed with the sender’s private key before encryption, allowing the recipient to verify the sender’s identity and the message’s integrity using the sender’s public key.
|
||||||
|
|
||||||
|
- **Security Enhancements with PKC:**
|
||||||
|
- **Message Confidentiality and Integrity:** With PKC, each DM is encrypted and signed, ensuring that only the intended recipient can read the message, and verifying that it has not been tampered with.
|
||||||
|
|
||||||
|
### 3. Admin Messages: Enhanced Security with PKC and Session IDs
|
||||||
|
|
||||||
|
- **Key Exchange with DH Curve25519:**
|
||||||
|
|
||||||
|
- **Initial Key Exchange Setup:**
|
||||||
|
|
||||||
|
- **Key Generation:** A Diffie-Hellman (DH) key exchange occurs using Curve25519 upon first communication between nodes. This generates a shared secret for establishing a symmetric encryption key.
|
||||||
|
- **Hardware Support:** Curve25519 is supported in hardware, ensuring efficient and secure key exchanges.
|
||||||
|
- **Shared Secret:** The derived shared secret is used for all subsequent communications between the nodes.
|
||||||
|
|
||||||
|
- **Use of Shared Secret for Encryption:**
|
||||||
|
- **Symmetric Encryption:** Following the key exchange, messages are encrypted and decrypted using the shared secret with symmetric encryption algorithms like AES-CTR or AES-CCM.
|
||||||
|
- **Efficiency:** Symmetric encryption, especially when based on a secure DH exchange, balances security and performance, making it ideal for real-time applications.
|
||||||
|
|
||||||
|
- **Session ID for Admin Messages:**
|
||||||
|
|
||||||
|
- **Session ID Usage:** Session IDs are generated for each admin session and used as an additional value inside the encrypted packet. This ensures that each session is secure and unique.
|
||||||
|
- **Session Duration:** The session ID is valid only for a short duration (e.g., 300 seconds) and is discarded once the session ends or after the next control message is sent.
|
||||||
|
|
||||||
|
- **Security Enhancements with PKC and Session ID:**
|
||||||
|
- **Replay Attack Mitigation:** By utilizing session IDs, replay attacks are effectively mitigated. Old session IDs cannot be reused, ensuring that intercepted packets are invalidated.
|
||||||
|
- **Isolated Impact:** The use of session IDs confines any issues related to session management to admin messages, without affecting broader communication functions like DMs or Chat Channels.
|
||||||
|
|
||||||
|
### 4. Overall Security Architecture
|
||||||
|
|
||||||
|
- **Integration of PKC with Existing Systems:**
|
||||||
|
|
||||||
|
- **Direct Messages:** PKC enhances the security of DMs by providing encryption, authentication, and integrity through the use of asymmetric encryption and digital signatures.
|
||||||
|
- **Admin Messages:** The combination of PKC and session IDs secures admin-related operations, providing an additional layer of protection for critical functions.
|
||||||
|
|
||||||
|
- **Use of PSK with Existing Systems:**
|
||||||
|
|
||||||
|
- **Channels:** PSKs continue to be used for group communication, ensuring secure message exchanges within the channel.
|
||||||
|
|
||||||
|
- **Scalability and Performance:**
|
||||||
|
- **Efficient Use of Resources:** PKC for DMs leverages asymmetric encryption for secure communication, while PSKs for Chat Channels and session IDs for admin messages optimize resource consumption on the platform.
|
||||||
|
- **Memory Management:** The selective use of PKC, PSKs, and session IDs ensures that memory and computational resources are effectively managed, allowing the system to scale while maintaining high security.
|
||||||
|
|
||||||
|
## Conclusion
|
||||||
|
|
||||||
|
PSKs and the expanded use of PKC and session IDs across different MCU architectures—ESP32, nRF52, and ARM—demonstrates a tailored approach to security that balances performance, power consumption, and memory management. Each architecture's strengths are leveraged to ensure that secure communications are maintained without compromising the efficiency or scalability of the system. This approach provides robust security for a wide range of applications, from low-power wearable devices to more powerful, feature-rich systems.
