A provably secure secret handshake with dynamic controlled matching

Abstract A Secret Handshake is a protocol that allows two users to mutually verify one another’s properties, and in case of simultaneous matching, to share a key used to secure subsequent communications. In this paper, we present the first Secret Handshake scheme that allows dynamic matching of properties under stringent security requirements: in particular, the right to prove and to verify is strictly under the control of an authority. This work merges characteristics of Secret Handshake with features peculiar to Secure Matchmaking.
