[security] Introducing signing support to MySensors



  • @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 🙂



  • @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.


  • Contest Winner

    @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)



  • @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/


  • Contest Winner

    @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.


  • Admin

    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.



  • This tutorial is up to date for 2.0 release ?


  • Contest Winner

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



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



  • 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?


  • Contest Winner

    @NiklasO @marceloaqno is working on this.



  • 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?


  • Contest Winner

    @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.



  • @Anticimex said:

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


  • Contest Winner

    @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.



  • 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


  • Contest Winner

    @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.

    @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.


  • Contest Winner

    You can read about personalization here.



  • 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!


  • Contest Winner

    @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.



  • @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!


  • Contest Winner

    @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.

    @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.



  • @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!

  • Contest Winner

    @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.



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

    * 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)
    *

    @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.


  • Contest Winner

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


  • Contest Winner

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



  • @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.


  • Contest Winner

    @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.



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


  • Contest Winner

    @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.



  • @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.
    😞


  • Contest Winner

    @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.



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


  • Contest Winner

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



  • @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!

    --------------------------------
    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


  • Contest Winner

    @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.



  • @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

  • @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


  • Contest Winner

    @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.



  • @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.


  • Contest Winner

    @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.


  • Admin

    @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


  • Contest Winner

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



  • @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


  • Contest Winner

    @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.

    and this is the serial output:

    This key will be stored in EEPROM as AES key:

  • Contest Winner

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


  • Contest Winner

    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.



  • @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


  • Contest Winner

    @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.


  • Contest Winner

    @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.



  • @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


  • Contest Winner

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


  • Contest Winner

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



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


  • Contest Winner

    @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.



  • 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


  • Contest Winner

    @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.



  • @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.


  • Contest Winner

    @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?



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


  • Admin

    @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)



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


  • Contest Winner

    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:

    * 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 ArduinoGateway prints data received from sensors on the serial link.
    * The gateway accepts input on seral which will be sent out on 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)
    *

    The gateway sketch include a test of the atsha which I don't think belong there. You can probably remove the include and the test function.



  • @tbowmo it compiles with this:

    #include <drivers/ATSHA204/ATSHA204.h>

    However, I cannot confirm that the singing is working - I need more time to set-up a node to test it.


  • Admin

    @Anticimex

    It's the default sketch, that itead is putting in the gateway, including a simple hardware self-test routine.

    I would like to keep it there, in case people run into troubles.. Then they can go back to factory stock firmware...



  • @Anticimex You suggest to remote it? It compiles fine if I remove it. I will set-up a node tomorrow to test signing with #include <drivers/ATSHA204/ATSHA204.cpp> removed.


  • Contest Winner

    @tbowmo may I suggest an update which would switch out the include of the cpp file and the test if atsha based signing is enabled? Or is it too late to ship firmware updates to iTead?


  • Admin

    @Anticimex

    Such a change won't affect the firmware that is put into the sensebender GW per se, as we don't use signing in the default sketch. I was about to suggest the same 🙂


  • Contest Winner

    @tbowmo then we have a way forward 🙂



  • @Anticimex
    sorry i didnt let hear anything from me for the last few days.
    i had the same problems with compiling the sketch. It depends on the signing. When you remove the #define MY_SIGNING_ATSHA204 the you can compile but when the singning is defined you get an error until you remove this line:
    #include <drivers/ATSHA204/ATSHA204.cpp>

    i have removed the line and defined the signing and for me works the singing and encryption.

    but i have an another problem, i dont know if i am right here or i better have to post in the sensebender micro forum, i posted that i had some troubles with the space on the sb micro, i have removed the #define my_debug that solved my space problem, but now i have observed that the node is starting and sends few times the temp and humidity but after the few times nothing happens anymore.



  • i observed, when i hold the sensor in the fingers so that it will be worm, and start the node then it sends all minute the temp, but when the temp goes donw to the room temperature the the node sends only when the humidity or temp changes over the threshhold, but in the room i dont have much changes and i think that when the node does not send about longer time, that the the problem comes up.
    I tested it in some different distances, on another floor but in very short distance too. I dont think that is a radio problem.
    What do you think about?
    The Problem is, that i cant debug the node because i disabled it because of space problems.
    Thank you

    Please post these kind of things in the sensebender thread, they are not signing related.



  • @Anticimex I have a quick question. I have the following in the node log:

    both the GW and the node have #define MY_SIGNING_REQUEST_SIGNATURES
    Am I missing anything? Why signing is skipped?


  • Contest Winner

    @alexsh1 has the node and gateway successfully exchanged their signing preferences? It is done at node startup.

  • Contest Winner

    @alexsh1 is that all? It looks like it has not reached the signing setup part yet. Is node and gw alive or are one of them hanging?



  • @Anticimex Yes, I am afraid. The GW is showing
    "0;255;3;0;9;Message is not signed, but it should have been!
    0;255;3;0;9;!TSF:MSG:SIGN VERIFY FAIL"

    Yes, both node and GW are fine, but messages are not reaching the GW as signing is required.


  • Contest Winner

    @alexsh1 at startup of the node, it sends its signing preferences to the GW (assuming you have selected a signing backend, atsha204a or soft signing). The GW will then reply with its own preference to inform the node that it should sign messages. If the GW said that it rejects messages because they are unsigned, it suggests that the GW require signatures from that node, but the node does not realize that it needs to sign them. So either the node is not properly configured to sign messages or there have been a radio issue preventing message exchange during startup.



  • @Anticimex After forcing all nodes to sign with #define MY_SIGNING_GW_REQUEST_SIGNATURES_FROM_ALL

    RF issue?


  • Contest Winner

    @alexsh1 I think the problem is that you use the GW you reported was malfunctioning where the self test reported that the atsha204a did not answer as expected. And that you now try to use that device. Since the log said that a message failed to be signed.



  • @Anticimex No, the GW I am using is Mega 2560 with W5100 not the sensebender GW.
    It has been working for many months after I resolved a power issue. However, signing is a different thing...


  • Contest Winner

    @alexsh1 seeing your latest log it appears you have rf issues. You have NACKs.



  • @Anticimex It seems that the legacy of nrf24l01+ RF communication is still chasing me ...
    :((((((

    Thank for your help



  • @Anticimex I did manage to make it after swapping a radio module:

    But it still throws many SIGN FAIL.


  • Contest Winner

    @alexsh1 the log still looks like you sometimes don't get the nonce you requested so signing times out and fails. I am still quite sure that if you looked in the log on the other side, it would show NACKs on some nonce transmissions. Signing won't work when those fail.



  • @Anticimex This is what we discussed before, this is not a signing issue. Guess what? I did notice that RF is much better with non-amplified nrf24l01+. Given my experience in the past with nrf24l01+ pa+lna, I have just soldered out and replaced AMS1117-3.3V (Mega 2560 works on 5V so I need a stable 3.3V source, which I cannot take from Mega's 3.3V pin for a hungry nrf24l01+pa+lna) and signing started working!
