[security] Introducing signing support to MySensors

meddie

@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.

meddie

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

Anticimex

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:

2076 Will not sign message for destination 255 as it does not require it

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

Anticimex

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

alexsh1

@Anticimex No, straight at the beginning I got this:

Anticimex

@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?

alexsh1

@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.

Anticimex

@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.

alexsh1

@Anticimex After forcing all nodes to sign with #define MY_SIGNING_GW_REQUEST_SIGNATURES_FROM_ALL
got this:

RF issue?

Anticimex

@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.

alexsh1

@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...

Anticimex

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

alexsh1

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

Thank for your help

alexsh1

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

But it still throws many SIGN FAIL.

Anticimex

@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.

alexsh1

@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!

This is the second time I change AMS1117 in one year. Very odd
Anyway, very much appreciate your help on signing! Very helpful

Anticimex

@alexsh1 glad you got it working again :)

alexsh1

@Anticimex Last time, I took me moths to resolve it. AMS1117 has not failed completely, but was working intermittently. This had a major impact on how nrf24l01+pa+lna was working. Unfortunately, range and signing were affected.
My theory is that it is getting probably 45-50C in my GW - there are many wires and it is a very tight fit. This may contribute in such AMS1117 behavior. Or probably just a bad batch.

Anticimex

@alexsh1 sounds like it. I've always considered the AMS1117 to be a trustworthy part.
