[security] Introducing signing support to MySensors

Anticimex

@alexsh1 Can you please be a bit more elaborate on what "Compiling breaks" mean? @tbowmo a known issue?

alexsh1

@Anticimex @tbowmo OK, I take a default sensebenderserial.ino sketch and add one line for signing "#define MY_SIGNING_ATSHA204" and have the following errors (2.2.0-dev):

@alexsh1 Try to comment this line.
If it still fails to compile, also comment out this block and this block.

@Anticimex Commenting #include <drivers/ATSHA204/ATSHA204.cpp> did help, I can compile the sketch.

However, have a different issue now:

Anticimex

@alexsh1 That is a radio issue. You have NACK on !TSF:MSG:SEND.

Anticimex

@tbowmo We probably should conditionally include drivers/ATSHA204/ATSHA204.cpp based on the MY_SIGNING_ATSHA204 flag. Otherwise the ATSHA204.cpp file will be included in multiple places if ATSHA204 signing is enabled in the gw.

alexsh1

@Anticimex it says

Shall I try to increase timeout?

Anticimex

@alexsh1 First you have to resolve the NACKs. It will not help to increase the timeout if messages never arrive.

alexsh1

@Anticimex I think I have resolved it by changing this:

#define MY_RF24_PA_LEVEL RF24_PA_HIGH

to

#define MY_RF24_PA_LEVEL RF24_PA_LOW

@Anticimex

Do you think that I may have verification timeout due to having a mixture 2.1.1 and 2.2.0?

Anticimex

@alexsh1 Hm, it should not be a problem. Assuming your log snippet is from the GW, it basically says that it successfully transmit the nonce to your node as requested to, and then it expects the node to provide a signed message to the GW within a certain timeout. The node fails to do this within that time so the GW times out and will not accept the message if it arrives later on.
So there are two options;

The node takes too long to process the received nonce, sign the message and send it back (perhaps many repeater hops between node and gw, this can be resolved by increasing the signing timeout at the GW side).
The node does transmit the signed message but fails with a NACK. The GW will never see this message and therefore assumes the node did not send it and correctly times out.

@Anticimex On the node, changing nrf24l01+ orientation (I have two nrf24l01+ sockets) 90 degrees changed signing from

@alexsh1 Looks like RF performance was significantly improved by that change.

alexsh1

@Anticimex It seems to me that 90% of all issues is actually RF.
Very annoying!

Thanks for your help!

I am using latest beta (2.2.0b). Does anyone know what this means in the log:

!SGN:NCE:GEN

I think this is related to signing

Anticimex

@alexsh1 https://ci.mysensors.org/job/Verifiers/job/MySensors/job/development/Doxygen_HTML/group__MySigningDebugMessages.html

Anticimex

@alexsh1 to be more specific; the backend failed to generate a nonce. If you use the soft backed, it did not initialize properly (and you should have a log entry for that failure as well).
If using atsha204a, it either failed init like described above, or it failed to communicate properly (which should also be visible in other failures in the log)

alexsh1

@Anticimex Spot on -> there was a mistake :

#define MY_SIGNING_ATSHA204_PIN 3

and should have been

#define MY_SIGNING_ATSHA204_PIN 17

I was wondering why nonce was all zeros...

Anticimex

@alexsh1 excellent. Signing won't work well without proper communication with the chip :)
I considered just hanging if that happened but decided it was a bit too harsh and might disguise the problem in case UART debug isn't enabled.
