KNX IP secure and KKNX data secure implementation
Hi @Supergiovane ,
just in case you are searching for existing implementation of those two secure layers, I would like to point you to my implementation of the KNX data secure layer in this Arduino KNX stack: https://github.com/thelsing/knx/blob/master/src/knx/secure_application_layer.cpp
Here are some learnings from my journey while implementing it: https://github.com/thelsing/knx/issues/57
The data secure implementation was inspired by this one: https://github.com/calimero-project/calimero-core/blob/master/src/tuwien/auto/calimero/secure/SecureApplicationLayer.java
The KNX IP secure layer has not been implemented yet in the above KNX stack. But maybe this helps? https://github.com/calimero-project/calimero-core/blob/master/src/tuwien/auto/calimero/knxnetip/SecureSessionUdp.java
You will definitely want to read the KNX specs. AN158 (Data secure) and AN159 (IP secure).
Hi Nanosonde! Thanks! Yes, i also saw the Calimero implementation and i bought the ISO for KNX Secure. Thank you for pointing me out your Arduino KNX stack, i'll take a look!! I'm working on KNX Secure and i hope to release the first secure implementation before the summer arrives.
Nanosonde seems an italian name.
Hey there!
In case you are looking for an additional IP-Secure implementation, I just got this working with Python in xknx - it's still a draft though. https://github.com/XKNX/xknx/pull/875
There is a file in examples/ that might be helpful. https://github.com/XKNX/xknx/blob/ce1cda0cf6caa30f7bf8d33004e8b37f5da3f7a1/examples/ip_secure_calculations.py
If you need help to test a secure implementation, please feel free to ping me. I tried to connect to my secure KNX router but failed currently (signature verification failed for keyring)
Hi We are working on that, but we need time. We work on that in our free time.
