Abstract: In 2003, Boyd and Mao proposed two deniable authenticated key establishment protocols using elliptic curve pairings for Internet protocols, one is based on Diffie-Hellman key exchange and the other is based on Public-Key Encryption approach. For the use of elliptic curve pairings, they declared that their schemes could be more efficient than the existing Internet Key Exchange (IKE), nowadays. However in this paper, we will show that both of Boyd-Mao??s protocols suffer from the key-Compromise Impersonation attack.
