Abstract: Efficiency and safety can’t all take into account in normal authentication protocol. Aiming at the problem in heterogeneous integrated network, this paper proposes an efficient authentication protocol which includes full authentication procedure and fast re-authentication procedure. This paper reduces the authentication delay by reducing the number of message interactions in full authentication and reducing the number of authentication entities in fast re-authentication. And this paper uses hash chain method to ensure the safety and freshness of information. Using a formal analysis tools of AVISPA to analyze the security of protocol, and compared with the existing authentication protocols to analyze the efficiency, the analysis results show that the proposed protocol improves the authentication efficiency while ensuring the security, and improves the performance of heterogeneous integrated network.
