Anonymous password-based authenticated key exchange (APAKE) protocols are a topic of ongoing research interest. However, the security of existing APAKE protocols is generally provided in the random oracle model, and in these protocols, passwords are stored in cleartext on the server. However, proofs of security in the random oracle model do not necessarily imply security in the real world. Recent...
Password-based authenticated key exchange (PAKE) is applied widely in modern communication because that password is easy to be remembered and system has good scalability. But most of the existing PAKE protocol cannot meet the proposed security attribute. In this paper, we propose a strongly password-based three-party authenticated key exchange (3PAKE) protocol based on the Diffie-Hellman key exchange...
Recently, several group password-authenticated key exchange (GPAKE) protocols have been proposed, Byun and Wang et al also proposed different passwords group PAKE protocols successively, and the clients in their protocols were all in the same realm. However, in practice we also need to establish a secure communication channel between groups who are in different realms. So, we proposed a cross-realm...
