移动通信中双向认证和密钥协商协议

Mutual Authentication and Key Agreement Protocol for Mobile Communications

移动通信增值服务的关键技术之一就是设计既满足较差计算性能又具有良好安全性的协议。文章在Lowe改进的BANconcreteAndrewSecureRPC协议的基础上引入带密钥的哈希函数,生成一个新的移动通信认证和密钥协商协议Advanced-RPC。该协议规避了原协议存在的密钥泄漏风险,增加了向前安全性,同时提高了执行效率;与其它同类协议相比,也具有明显的高效性和简洁性。

The key technology of mobile value-added services is to design protocols,which can meet the poor computing power as well as being security.This paper proposes an Advanced-RPC protocol by adding hash function with key to the Lowe modified BAN concrete Andrew Secure RPC.The new protocol mends some undesirable properties in the old one,enhances forward security,and improves the running efficiency.Possessing of both secure and efficient properties r~ akes the proposed protocol suitable for the low power wireless communications.
