认证密钥协商使得通信双方在共享一个安全会话密钥的同时实现相互认证。针对无线网络,基于口令认证的密钥协商算法也许能降低系统资源开销,但通常不能有效抵抗字典攻击。针对无线设备的资源有限性,文中提出一种可证安全的、基于身份的、认证的密钥协商方案,所提出方案需要计算量少,能够抵抗冒充攻击并且满足密钥协商协议所要求的其它安全属性。 Authentication key agreement enables both communication parties to share mutual authentication while sharing one secure session key. For wireless networks, the password-based key agreement algorithm may reduce system resource overhead, but usually can not effectively resist the dictionary attack. Aiming at the limited resources of wireless devices, a secure, identity-based and key agreement protocol is proposed in this paper. The proposed scheme needs less computation, can resist the impersonation attacks and satisfies the requirements of the key agreement protocol Security attributes.
