Deniable authentication is derived from the Triple Diffie-Hellman algorithm presented in [Sys14]. Joining the room is a variation of the two-round mBD+P protocol presented in [ACMP10] where the authentication step has been made deniable. Leaving the room is the one-round mBD+S from [ACMP10].
The protocol computes a unified session key for all participants. This imposes, in particular, the necessity that all <math>plist_i</math>' is identical for all participants. -*++-H
