A secure group signature is required to be anonymous, that is, given two group signatures generated by two different members on the same message or two group signatures generated ...
This paper presents an efficient password-based authenticated encrypted group key agreement protocol immune to dictionary attack under the computation Diffie-Hellman (CDH) assumpt...
Abstract—Password-authenticated key exchange (PAKE) protocols are designed to be secure even when the secret key used for authentication is a human-memorable password. In this pa...
Abstract Traditionally, research in secure group key agreement focuses on minimizing the computational overhead for cryptographic operations, and minimizing the communication overh...
Users often wish to participate in online groups anonymously, but misbehaving users may abuse this anonymity to disrupt the group's communication. Existing messaging protocol...
