Aimed at the problems that the identity authentication protocol in the wireless network is vulnerable to forgery attack,replay attack,user imitation attack,with high computational overhead,and can not provide anonymity,an identity authentication key agreement protocol based on three factors(password,smart card and biometric)is proposed.The mutual authentication between communication entities was proved by BAN logic,and the scheme was simulated by AVISPA tool.Security analysis shows that the authentication protocol can realize anonymity,mutual authentication,session key negotiation and resist common attacks.Performance analysis shows that the authentication protocol has the lowest communication overhead and higher efficiency.
