| 摘 要： | 针对基于PKI认证的有线网络与基于IBE认证的无线网络混合组网时,因安全策略、密码体制的不同而导致节点间身份认证困难的问题,设计了一种基于零知识证明的跨PKI/IBE域的身份认证方案,在两个异构信任域之间设置一个零知识证明承诺值代理节点,在此基础上,设计了一个异构信任域身份认证协议,实现域间实体的身份认证,并分析了该协议的正确性、安全性和效率,结果表明其可行有效.

| Abstract: | In a hybrid network system which combines a wired network adopting PKI authentication and a wireless net- work adopting IBE authentication, it is difficult to authenticate other nodes in view of the different security polices and crypt- osystem. To solve this problem, a cross-domaia authentication scheme based on zero knowledge proof is proposed. An agen cy node is settled between the two heterogeneous trustworthy domains to certificate nodes＇ commitments in the zero knowl edge proof. Then a authentication protocol between heterogeneous trustworthy domains is designed to realize the authentica- tion between nodes in different domains, and the correctness, security and efficiency of the protocol are analyzed. The results show that the proposed protocol is feasible and effective. |
