Weaknesses of the Boyd-Mao Deniable Authenticated key Establishment for Internet Protocols
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
