Dear all, after the last call we would like to close the security section in minimal. We wrapped up all comments from the previous days and from the meeting and here is our proposal:
This draft assumes the existence of two cryptographic keys, K1 and K2. EBs SHOULD be authenticated with key K1. DATA, ACKNOWLEDGEMENT, and MAC COMMAND frame types SHOULD be authenticated and encrypted with key K2. For early interoperability, K1 MAY be set to "6TiSCH minimal15". K2 SHOULD be a randomly generated high entropy cryptographic key. Key distribution is out of scope. I would like to encourage everybody to see if this texts covers all what we want for minimal, and provide consensus. We need to move forward. kind regards, Xavi
