基于身份认证的无线安全密钥交换

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。

ID Authentication-based Key Exchange for Wireless Security

Authenticated key exchange （AKE） protocols are designed to allow mutual authentication and generation of a cryptographically-secure session key. For wireless security, the password-based authentication scheme is usually vulnerable to dictionary attack though might have a low system cost. This paper proposes an ID authentication-based key exchange scheme for wireless security, which has light computational overhead, is resistant to impersonation attack, and also of other security attributes.
