Hi Carsten, Some more loose thoughts about the secure discovery topic you raised in T2TRG today, er … yesterday. Part of the reasoning seems similar to that of which party in an authenticated key exchange should reveal its identity first. And one party has to go first, compare SIGMA-I vs. SIGMA-R [1]. It seems to me that a similar setting can be mapped to this domain, so secure discovery can be supported by a set of AKE-like protocols. Which variant to use depends on what is most sensitive, the identity/intent of the party that wants to discover or the resource being discovered. Perhaps one and the same protocol can be used in different directions, so only the initiating party of the security protocol differs between deployments. My 2 cents.
