Now I got Soft Signing to work, although I'm not yet sure why it works now:
/** SOFT SIGNING **/
#define MY_SIGNING_SOFT_RANDOMSEED_PIN 7
#define MY_SIGNING_SOFT
#define MY_SIGNING_REQUEST_SIGNATURES
/** END SOFT SIGNING **/
I think the problem was that "the simple password flag is mutually exclusive" (thanks @Anticimex).
Now everything works as expected!
@anticimex I think I got it working. The problem was that i used #define MY_SECURITY_SIMPLE_PASSWD instead of #define MY_SIGNING_SIMPLE_PASSWD (did I read the wrong docs? https://www.mysensors.org/apidocs-beta/group__SigningSettingGrpPub.html#gaedf8ec407fbde609a520ea0d95da2aac)
With that, only nodes with that password are able to communicate. Still needs some testing, but seems to work.
That's for the SIMPLE_PASSWD part. Next step would be getting Soft Signing to work, I will try that now and then send the debug logs.
Thanks already, if everything else fails, I'm now able to use at least the SIMPLE_PASSWD.
@anticimex I think it's the GW:
11607 SGN:PRE:NSUP,TO=42
11613 SGN:PRE:XMT,TO=42
But I can't find what I've done wrong:
// Enable debug prints to serial monitor
#define MY_DEBUG_VERBOSE_SIGNING
// Enables and select radio type (if attached)
#define MY_RADIO_NRF24
/** SIGNING AND ENCRYPTION **/

#define MY_PORT X

@anticimex what I've now done is I'm just using the MY_SECURITY_SIMPLE_PASSWD flag.
This is my sensor nodes output:
2154 SGN:PRE:SGN NREQ
2158 SGN:PRE:WHI NREQ
2166 SGN:PRE:XMT,TO=0
2170 SGN:PRE:WAIT GW
2205 SGN:PRE:NSUP
The sensor node can send messages to the GW, but the GW also accepts messages from nodes without signing, which is not yet what I wanted.
I'm now checking if GW and Sensor agree on Nonce and HMAC
@b1ackra1n
Okay got the signing debug prints (sensor node)

currently I'm trying it with these settings:

Still trying to get those signing debug logs to work, but I hope these logs already help
Hey guys,
so encryption and signing seems to be exasperating. I've tried it over and over, read the documentation and some forum posts and tried to make it work.
My goal is to have all my nodes to communicate encrypted and signed, so that nothing else but my nodes can read the sensor data and send sensor data to the Gateway.
I do not have an ATSHA so I want to go with soft signing. What I've done so far:
/** SIGNING AND ENCRYPTION **/
// Setup Soft Signing
#define MY_SIGNING_SOFT
#define MY_SIGNING_SOFT_RANDOMSEED_PIN 7
#define MY_SIGNING_REQUEST_SIGNATURES
#define MY_SECURITY_SIMPLE_PASSWD "XXXXXXXXXXXXXXXX"
//#define MY_RF24_ENABLE_ENCRYPTION
/** END SIGNING AND ENCRYPTION **/
I've tried this out with and without Simple Password enabled, but as I understand it correctly, using the Personalizer is more secure so I want to go with the personalizer.
What I get:
I can't get behind this security and signing thing as I can't get it running. Can you guys help me?
Thanks in advance
Tom
