针对L i‐L ee协议通信开销大、计算复杂性高等缺陷,提出一种改进的高效匿名认证密钥协商协议。在保留原协议安全属性基础上,重新设计原协议中本地代理与外地代理通信会话密钥建立机制,支持会话密钥更新功能。性能分析结果表明,与L i‐L ee协议相比,改进协议具有通信成本低、计算开销小等优势,更适用于无线通信应用环境。
針對L i‐L ee協議通信開銷大、計算複雜性高等缺陷,提齣一種改進的高效匿名認證密鑰協商協議。在保留原協議安全屬性基礎上,重新設計原協議中本地代理與外地代理通信會話密鑰建立機製,支持會話密鑰更新功能。性能分析結果錶明,與L i‐L ee協議相比,改進協議具有通信成本低、計算開銷小等優勢,更適用于無線通信應用環境。

An improved efficient anonymous authentication protocol with key agreement was proposed to overcome large commu‐nication overhead and high computational complexity of Li‐Lee’s protocol .By maintaining security attributes of the original pro‐tocol ,the session key establishment mechanism between the home agent and the foreign agent was redesigned in the improved protocol .Furthermore ,session key update function was supported by the improved protocol .The performance analysis shows that ,compared with the Li‐Lee’s protocol ,the improved protocol has advantages of low communication cost and computational complexity ,and it is more applicable for wireless communications .
