[security] Introducing signing support to MySensors

Anticimex

Thanks @duovis,
Yes, I welcome anyone who has the HW to provide a IO routine for I2C-variants of ATSHA204A. I don't have the hw myself though.

duovis

@Anticimex Ok, I'll try to play with it and see if I can come up with something that works on I2C.

Anticimex

@duovis Great. I'll happily review any code. You should only need to worry about the low level stuff.

Soloam

Hello all!

Two fast question! Can I have nodes working with ATSHA204A chip and others with software?

And, can I have nodes with signing on and others off? Or if I add signing to my network, all nodes must have it?

Thank you all!

Anticimex

@Soloam
You can mix nodes with soft signing and ATSHA signing as you like.
You can mix nodes with signing on and off as well. The GW will only sign messages to nodes that require it, and it will also only check signatures from nodes that require signatures. So you can have one node which support/require signing and another which don't. The GW will be able to exchange messages with both nodes.

Soloam

Great work indeed!

Thank you @Anticimex

Anticimex

@Soloam thanks

alexsh1

Slightly silly question, but did anyone manage to get signing working (MySigningAtsha204Soft signer;) on Arduino Uno on MS 1.5.4 on the Ethernet gateway please? I am going out of memory and really hate to upgrade it to Mega

Anticimex

@alexsh1 if you feel adventurous try 2.0.0-beta2, or if you are patient, go to 2.0.0 in a few months and redesigns will have made space available for you.

alexsh1

@Anticimex Thanks - I am currently trying an Ethernet GW and a node (Sensebender Micro) with dev branch. I am stuck at personalisation. I cannot lock data. Any idea what I am doing wrong?

This is Sensebender (with ATSHA204):

Anticimex

@alexsh1 actually, I have never actually locked data. Could be a bug there. But I also highly recommend that you don't. If you do, you will never be able to change hmac key in that device.

alexsh1

@Anticimex So this is no problem if the key is not locked? I was just following the manual

On a separate note, I cannot get soft_serial written into the EEPROM:

#define LOCK_CONFIGURATION
//#define LOCK_DATA
//#define SKIP_KEY_STORAGE
//#define USER_KEY
//#define SKIP_UART_CONFIRMATION
#define USE_SOFT_SIGNING
#define STORE_SOFT_KEY
#define USER_SOFT_KEY
#define STORE_SOFT_SERIAL
#define USER_SOFT_SERIAL
#define STORE_AES_KEY
#define USER_AES_KEY```

I have defined the key under #define MY_SOFT_SERIAL [key]

Personalization sketch for MySensors usage.
-------------------------------------------
This value will be stored in EEPROM as soft HMAC key:
#define MY_SOFT_HMAC_KEY [deleted]
Using this user supplied AES key:
#define MY_AES_KEY [deleted]
EEPROM configuration:
SOFT_HMAC_KEY | [deleted]
SOFT_SERIAL   | FFFFFFFFFFFFFFFFFF
AES_KEY       | [deleted]
--------------------------------
Personalization is now complete.

Anticimex

@alexsh1 Hopefully the manual informs about the risks with locking data (that you cannot change the key afterwards). Atmel is somewhat vague on the security implications; they say that you can not read the key anyway but it is "more secure" to lock data. But personally, I have not found a way to read it, and I prefer to be able to change my HMAC key in my devices if it should be compromised.

Strange that you don't get the soft serial. I see nothing obviously wrong with your config. But I do see that you probably sensored your uart log a bit too hard because there are other lines missing there.
You should have seen this

Using this user supplied soft HMAC key:
#define MY_SOFT_HMAC_KEY [deleted]

if you have enabled this:

#define STORE_SOFT_KEY
#define USER_SOFT_KEY

You are sure you have no #undef or some accidental comment or similar. As you see in the personalizer code, it is not that complicated. If the flags are enabled, you should at least get some printouts. But since (if your UART dump is correct) you get nothing, I suspect the flags are not really "on".

OK, it was Arduino glitch - any changes in the sketch were not reflected on the compilation. Rebooted my PC and restarted Arduino and all works as expected.

A few questions: Mixing ATSHA204 and soft signing - Does HMAC key (one stored in ATSHA204 of say a node and another one in GW's EEPROM) have to be the same? Also I understand one can store HMAC key on both ATSHA204 and EEPROM of one device (say, Sensebender)? I understand that SOFT_KEY has to be unique for every device?

Anticimex

@alexsh1 Ok, well Arduino IDE sucks totally.

You can mix ATSHA204A and soft signing as much as you like. But for any two nodes to exchange signed data the HMAC keys have to be identical.
Yes, you can store a HMAC key in both ATSHA204A and EEPROM. These can be different if you like (and I recommend they are as the EEPROM can be dumped if the node falls into the wrong hands).
However, if you want that node to communicate signed data to another node, that node must use a matching HMAC key.
SOFT_KEY is the HMAC key stored in EEPROM, it must not be unique for every device. If it is, no device will be able to sign data to any other node and expect that node to accept that data.
SOFT_SERIAL on the other hand, must be unique to serve any useful purpose for whitelisting. If you use the ATSHA204A, the serial fused in the device will be used and that cannot be changed, and is according to Atmel, unique.

alexsh1

@Anticimex Ok, but is there a reason why one would have HMAC key in both ATSHA204a and EEPROM?

Anticimex

@alexsh1 no, not really. If you have a atsha204a the only reason to not use it would be performance. Software signing executes slightly faster due to the single write protocol of the atsha.

alexsh1

@Anticimex Thanks very much for your help - I must admit it was a bit of a challenge to jump straight away from a stable 1.5.4 to 2.0 beta

Anticimex

@alexsh1 yes there have been a lot of changes but hopefully they are perceived as improvements. Feedback on signing usability is always welcome

alexsh1

@Anticimex BTW, is signing compatible between 1.5.4 and 2.0b?

Anticimex

@alexsh1 no, it is not

alexsh1

@Anticimex Right, this is why I am not able to sign 1.5.4 nodes with 2.0b GW.
In fact when I inserted #define MY_SIGNING_REQUEST_SIGNATURES into the GW code, some nodes stopped working and I think it has to be with signing as GW is throwing a lot of messages that signing failed.

Bottom line is that I need to upgrade pretty much all sensors

Anticimex

@alexsh1 yes, Unfortunately. But it is a huge release upcoming. And a major version step, hence the incompatibilities. Hopefully, the changes made will make it easier to do future maintenance.

cingolanifede

Hi. Is there any difference in using RFM69? Signing is supported using that radio? Thanks

Anticimex

@cingolanifede signing has nothing to to with which radio you choose so yes. It supports any transport, but to my knowledge it has only been actually tested with nrf24 and rfm69.

alexsh1

@Anticimex I must admit that signing is working really-really nicely on my custom made nodes (Soft sign and ATSHA204A)

Apart from a small issue with the sensebender, which I believe is not a signing issue, it is working like a charm. All credit to you! Thank you

@alexsh1 I'm really glad to hear that. Thank you! Glad that signing is being used and is perceived as something not to complicated to bother with. It sets us apart from many other projects dealing with the same thing

alexsh1

@Anticimex I did not say it was not complicated
Just kidding - speaking just for myself, it did require some time investment to understand the concept and then upgrading my gateway and my nodes (I am still in the process of rolling signing across the rest of my nodes) to MySensors 2.0b. I probably spent more time upgrading MySensors lib and breaking some hardware in the meantime (the SMA connector on the nrf24l01+ PA+LNA) than the actual signing.

Anticimex

@alexsh1 yeah, well if there is room for improvement in the documentation then feel free to help put with suggestions if there is anything unclear about that I use doxygen to document signing features, and a link is available on the GitHub "front-page" (the readme.md)

alexsh1

@Anticimex I think a noob's section would be good. Having said that, the point is that signing is not something beginners should touch. What do you think?

How about a section on the web-site? Somewhere here - https://www.mysensors.org/build/

Anticimex

@alexsh1 hm, yeah, perhaps something for @hek to consider. At least a link to the signing section of the doxygen docs could be placed there. I have tried to make the documentation as step-by-step friendly as I can. That said, as I also did the actual implementation, I may well be blind for certain aspects I take for granted that a "novice" does not.

hek

The next release of the main site will be much more flexible and integrated with openhardware-added projects. The idea is to allow community members to maintain their projects and/or "articles" themselves. The how-to for signing is a good example of an article.

Fabien

This tutorial is up to date for 2.0 release ?

Anticimex

@Fabien Yes, top post is now updated for 2.0.0. Documentation is in doxygen.

Fabien

Thank you @Anticimex I will update my network soon and had RFM69 Encryption too.

NiklasO

Trying this:
https://www.mysensors.org/build/raspberry

How do I enable signing and give the gateway the serial, hmac and aes-key when running on Linux? (rPi).

Edit: Pin 7 as random number generator maybe need some change?

Anticimex

@NiklasO @marceloaqno is working on this.

executivul

Hi,
I have about 100 ATSHA204 I2C variant to be used in a MySensors project.
Do you think that by modifying the personalizer sketch to disable the I2C bit in the configuration (0x03 word address) the chips can be set to be used as single-wire, or are they hardcoded to use only one protocol, but then why having the config bit?

Anticimex

@executivul The bit is readonly. You cannot change it. It is used to determine the variant of chip, not to select mode of operation.
From the documentation:
0_1478094689558_upload-93242040-4814-4ad6-8951-4ad4d1e99a23
But you are welcome to submit a pull request for adding support for I2C variants of ATSHA204a. I have none myself so I have not bothered looking into that and currently I am out of time to spend on it I am afraid.

Please excuse my noobish ignorance: How and where do I submit one?

Anticimex

@executivul By forking the MySensors core repository and create a local git branch, do your code, push it back to your fork on GitHub and then create a pull request from that. There are good guides on GitHub for how do do it.

meddie

ok, thank you, but do you know why the sketch didnt generate the keys, and instead of random i get only keys ffffffffffff ?
thank you

Anticimex

@meddie Without actually seeing your sketch it is pretty hard for me to help with anything
My guess is, you did not enable the proper defines to instruct it to generate and store any keys.

Anticimex

@meddie Sorry, missed that post.
You have SKIP_KEY_STORAGE defined so no keys will be stored. This is the default and intentional, to avoid people just executing the sketch and accidentally overwrite existing keys.
Furthermore, you have selected to personalize a ATSHA device, and have it generate the keys. That means that you have to define LOCK_CONFIGURATION or the ATSHA random number generator will not work.

Anticimex

You can read about personalization here.

meddie

Ah, thank you very much, yes now i get generated a key. But one more question the AES key will not be generated? I got only the HMAC Key, do i have to put the AES Key at myself?
Thank you very much!

Anticimex

@meddie Please read the documentation and the sketch carefully. It quite clearly states in both documentation and code that you need to define STORE_AES_KEY to generate and store an AES key.

meddie

@Anticimex
sorry sorry for so many questions, i have read the how to use already some times, but maybe its my bad english or the fear to do something wrong or to destroy the chip. I get a little bit unsure.

Now i get both keys. If i understood correctly, the keys are now stored, i have now to put the shown keys to the sketch as HMAC and AES Key, and run this sketch on the sensor nodes.
On the gateway on which i generated the keys i dont need to do anything more as to upload the gateway sketch ?
Thank you very much for your support!

Anticimex

@meddie assuming you locked the configuration of the atsha, no you should not need to do more.

@Anticimex
sorry i have one more question, because i didnt fully understand this. In the gettings started how to you wrote:

Pick a “master” device with serial debug port.
Set the following sketch configuration of the personalizer:
...

Enable SKIP_KEY_STORAGE
...

Execute the sketch on the “master” device to obtain a randomized key. Save this key to a secure location and keep it confidential so that you can retrieve it if you need to personalize more devices later on.
Now reconfigure the sketch with these settings:
...
Disable SKIP_KEY_STORAGE
...
Put the saved key in the user_key_data variable.
Now execute the sketch on all devices you want to personalize with this secret key.

on the first run i have to enable SKIP_KEY_STORAGE so i removed the comments.
But here in forum you write i have to disable this. After i has disabled it wroked fine for me.

But now i have to run the sketch on my node, and i think i have to disable the SKIP function too, because i need that the keys will be stored in the node.

So if i am right, the on both runs the SKIP function has to be commented out? Or i am wrong?
Thank you.

Anticimex

@meddie If your read the text carefully it says:
Set the following sketch configuration of the personalizer:
...
Execute the sketch on the “master” device to obtain a randomized key. Save this key to a secure location and keep it confidential so that you can retrieve it if you need to personalize more devices later on.
Now reconfigure the sketch with these settings:
...
Now execute the sketch on all devices you want to personalize with this secret key.

So in other words; you first use the settings described in the first setting, execute that once. Follow the instructions carefully. Write down the key you got. Then you reconfigure the sketch and execute it on all devices you want to personalize. That is, you execute it twice on the first device.
I wrote that you need to undefine SKIP_KEY_STORAGE if you want to store a key. But the first set of instructions in the documentation is not saying that you are supposed to store a key. It says "Execute the sketch on the “master” device to obtain a randomized key."

So the documentation is correct, and describe a flow where you personalize nodes and gateways with the minimum amount of changes needed. First you generate a key, and this step can actually be skipped altogether if you just make your own random key or password to use for HMAC/AES.
Then you reconfigure the personalizer to use your generated (or selected) key and write it to all your devices.

meddie

@Anticimex
but as i runned the sketch with SKIP_KEY_STORAGE defined, so no keys were generated.

i did not like to say that the documentation is incorrect, i like your documentation and your work very well! i just didnt understand it!

Thank you very much!
Greets Eddie

Anticimex

@meddie are you sure you ran with the exact settings described for generating the keys? The SKIP_KEY_STORAGE flag does not prevent the keys from being generated. They are still printed in the serial log. It prevents the keys from being stored to the atsha204a device.

meddie

i fear to write again, but my fail story goes on
i have uploaded on the gateway this sketch:

/**
* The MySensors Arduino library handles the wireless radio link and protocol
* between your home built sensors/actuators and HA controller of choice.
* The sensors forms a self healing radio network with optional repeaters. Each
* repeater and gateway builds a routing tables in EEPROM which keeps track of the
* network topology allowing messages to be routed to nodes.

*
* DESCRIPTION
* The EthernetGateway sends data received from sensors to the ethernet link.
* The gateway also accepts input on ethernet interface, which is then sent out to the radio network.
*
* This GW code is designed for Sensebender GateWay / (Arduino Zero variant)
*
* Wire connections (OPTIONAL):
* - Inclusion button should be connected to SW2
*
* LEDs on board (default assignments):
* - Orange: USB RX/TX - Blink when receiving / transmitting on USB CDC device
* - Yellow: RX  - Blink fast on radio message recieved. In inclusion mode will blink fast only on presentation recieved
* - Green : TX  - Blink fast on radio message transmitted. In inclusion mode will blink slowly
* - Red   : ERR - Fast blink on error during transmission error or recieve crc error
* - Blue  : free - (use with LED_BLUE macro)

please help me once again
Thank you

Anticimex

@meddie if you want your node to sign messages to the gateway you have to tell the gateway to require it. The log says that it does not require it and it is clear from your gateway sketch that you have disabled the requirement.
Is that your problem?
EDIT: I see that the messages are broadcasts, those will never be signed. So the "will not sign messages" are perfectly normal no matter how you configure your gateway in this case.
The problem, at least based on the node log is that your node cannot find a parent to communicate with for some reason.

Anticimex

@meddie for parsing the log file you can use this tool

Anticimex

@meddie I also see that you fail to find parent. Have you verified that you had working node-gateway communication before you enabled signing?

meddie

@Anticimex
Hi, i have just uploaded the GatewayW5100 Sketch to the Gateway and the HumidtyTemp Sketch to the Node and it works fine, but without signing and encryption.

Anticimex

@meddie You had encryption enabled when it failed? That could explain the failure of the broadcast if you did not have a matching setting between the nodes/gateway.

meddie

@Anticimex
yes the encryption was enabled. Should i upload the personalized sketch again with my keys?

Anticimex

@meddie You can just run an unmodified personalizer to have it read the EEPROM contents. That way you can verify that all devices share the exact same AES key. Assuming a mismatch in the AES key was the reason for the problem.
But I strongly encourage you to just enable one security feature at a time if you are not sure what you are doing or it will be hard to debug what is going wrong.

meddie

@Anticimex
yes, i try to activate one feature and when it works the next. So i decided to activate the encryption and then when it works then i try to activate the signing. But first i would to check the keys like you said and when i now upload the securitypersonalization sketch unmodified i dont get any output on the serial monitor.

Anticimex

@meddie Well, you have to make the patch to the baud rate and the changes we discussed earlier. I presume you did something necessary since you got output previously.

meddie

@Anticimex
when i run the personalizer sketch i see in all keys FFFFFF....... What does it mean that no keys are stored?

Anticimex

@meddie yes, that mean eeprom is in default state. The node has not been properly personalized.

meddie

@Anticimex
ok, i think i know what went wrong! But i dont know how to fix it. On the first run when i tried came the prompt to sens space to lock configuration i did it.
Now when i upload the modified personalization sketch with my keys i get this output on serial monitor:
of course i removed my keys with xx!

Device serial:   {0xXX,0xXX,0xXX,0xXX,0xXX,0xXX,0xXX,0xXX,0xXX}

Writing key to slot 0...
Data not locked. Define LOCK_DATA to lock for real.
--------------------------------
Personalization is now complete.
Configuration is LOCKED
Data is UNLOCKED

i thin this is the reason:

Skipping configuration write and lock (configuration already locked).

and what i find very interestin that the first two signs of AES Key are correct the rest of them are FFFFF

AES_KEY       | XXFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF

is it possible to unlock the configuration or did i kill the chip?
Thank you
Greets Eddie

Anticimex

@meddie you cannot undo a lock, and you have to lock the chip in order to use it. And it is not an error that it reports chip is already locked since you have locked it already.
Furthermore, AES key and eeprom has nothing to do with the atsha204a chip so the lock state of the chip is irrelevant.
Now, why your AES key is only partially stored, I am not sure. But my bet would be that you have an error in the line where you define it in the sketch. A space or something like that.
Finally, as long as you don't lock the data zone, and you don't tamper with the configuration bits for the atsha204a device, you cannot destroy the chip. You can always replace the hmac key, which is the only thing you program to the atsha using the personalizer. Except for the chip configuration bits, and those the sketch handles for you and once config is locked they are fixed in place.

meddie

@Anticimex
i checked the sketch already few times but i dont see an error.
here is the code i have only change my key with XX

meddie

@Anticimex
the interesting thing is when i upload the same sketch to the sensebender micro it works the AES Key will be stored correctly.
But on the Sensebender Gateway only the first two digits

Anticimex

@meddie sorry, I cannot see anything out of the ordinary. What hardware do you run on? SAMD? I know the personalizer to work on AVR.
Have you executed a sketch between personalizer rounds? Perhaps it overwrite parts of the eeprom.

meddie

@Anticimex
the troubles i have on sensebender gateway its a samd. On the micro (avr based) works fine.
On the gateway i didnt upload a sketch between. I have uploaded the personalizer sketch and after them i tried the unmoded personalizer.

Anticimex

@meddie ok, so samd hardware. @tbowmo is eeprom handling on samd fully compatible with avr? It would appear something is not quite right with eeprom writes (or reads) on samd.

tbowmo

@Anticimex

eeprom on samd is handled differently, than avr, since it's an external I2C eeprom. So the normal avr commands for read/write to the eeprom doesn't work.

the pieces that handle eeprom is located in MyHwSAMD.cpp between line 45 and 100
https://github.com/mysensors/MySensors/blob/development/core/MyHwSAMD.cpp#L45

Anticimex

@tbowmo
That may be, but I would still expect hwReadConfigBlock and hwWriteConfigBlock to be chip agnostic.

meddie

@tbowmo
sorry can you say me please what i have to add to the sketch that will store my aes key on the sensebender gateway?
I am a very very noob
thanks

Anticimex

@meddie could you please try an experiment?
Configure the personalizer to use soft signing and store a soft hmac key and serial to eeprom? Just make up some numbers as keys and see if the same problem happen with those or if it is just the AES key that fail.

meddie

yes of course!!!

@Anticimex
and this is the serial output:

This key will be stored in EEPROM as AES key:
#define MY_AES_KEY 0x6A,0x2B,0xF7,0xFB,0x03,0x8D,0x03,0x85,0x4D,0xDA,0x2D,0x89,0x9F,0xAD,0x8B,0x4F
EEPROM configuration:

SOFT_SERIAL   | 10FFFFFFFFFFFFFFFF
AES_KEY       | 6AFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF
--------------------------------
Personalization is now complete.

Anticimex

@meddie ok, clearly there is some issue with eeprom storage on samd then.

Anticimex

We will investigate this further. Thanks for identifying the issue. Perhaps you could test signing with atsha on the gateway. That should work since it does not depend on eeprom.

meddie

@Anticimex
thank you very much for your support and for your patience with me!!!!
i just tried and the signing is working fine!!!!
i look forward to try the encryption! i

Anticimex

@meddie you are so welcome! Glad that signing works for you. That is actually more complicated than encryption. We (the core team) have confirmed a problem with the write routine to the I2C eeprom on the SenseBender gateway. So people are investigating.

Anticimex

@meddie the development branch has been updated with a bug fix for the eeprom problem on samd based boards. If you pull the latest changes you should be able to properly personalize the AES key so that encryption will work.

meddie

@Anticimex
Hi, i just tried it out and now it and it has worked! The Aes key is stored correctly! BUT i get now an error on compile the gateway sketch

C:\Users\meddie\Documents\Arduino\SenseebnderGW_LAN_NRF24\SenseebnderGW_LAN_NRF24.ino\SenseebnderGW_LAN_NRF24.ino.ino: In function 'bool testEEProm()':

i could use the stable lib again then it should compile, but i think you would like to know that an error occours.
Greets Eddie

Anticimex

@meddie thanks for reporting! @tbowmo something that slipped through the Jenkins filter?

Anticimex

@meddie the sketch you compile, is it from the MySensors library examples tree, the external examples repository, or a local sketch?

meddie

@Anticimex
its combined from two example sketches sensebendergateway and gatewayw5100 example sketch

Anticimex

@meddie ok, if it is a local construction, it might be an expected error due to api changes in the library, in which case you need to update locally. The examples from the repository should compile ok.

meddie

i used the stable lib and comiled the sketch both features are now working encryption and signing! Thank you very much!!!!! I will try to update the example lib and try again.

I got just the next problem the space from sensebender micro is not enought to use all three features signing, encryption and ota. When i use AES and Signing i get over 109%, when i use the example sketch temp and humidty meassure.

Greets Eddie

Anticimex

@meddie you could consider using a conversion board (@tbowmo has published one at openhardware.io) and use rfm69 radios which do AES encryption in hw. It should put less strain on memory resources.

alexsh1

@Anticimex I am using a default SensebenderGatewaySerial sketch and get the following error when compiling:

Error compiling for board Sensebender Gateway.

If I delete "#include <drivers/ATSHA204/ATSHA204.cpp>", it compiles just fine.
Any ideas please?

I am using Mysensors 2.1.1, Arduino IDE 1.8.1 and latest SAMD board def.

Anticimex

@alexsh1 That is because the sketch has this line

#include <drivers/ATSHA204/ATSHA204.cpp>

@tbowmo Is it intentional to include the cpp and not the header in the sketch?

alexsh1

@Anticimex Thanks! I can confirm it compiles fine with the header included rather than the cpp. I suppose it was not an intention

tbowmo

@alexsh1

What environment are you building in? platform.io ? Or?

I know it's awkward to include the cpp file, but it must have been done intentional at some point in time, and arduino way of doing things are very weird at times..

Btw it does compile fine for me (even with the .cpp as include)

alexsh1

@tbowmo No, I am just using Arduino IDE in Windows 10

Anticimex

I tried building the sketch in Arduino 1.8.1 on Windows 10. Worked fine here. In your log, the sketch name looks changed. It does not end with -2.1.1 here.

@Anticimex Sorry, my bad I forgot to mention that the sketch compiles OK as is.
Only when I add signing:

//#define MY_SIGNING
#define MY_SIGNING_ATSHA204
#define MY_SIGNING_REQUEST_SIGNATURES
#define MY_SIGNING_ATSHA204_PIN 17

It fails to compile:
