一种基于代理签名机制的改进认证协议的设计与研究

Design and research of improved delegation-based authentication protocol

Lee提出了一种适用于便携式通信系统的代理认证协议。该协议在在线认证过程的基础上提出了一种离线认证过程来优化本地服务器的性能。研究表明该离线认证协议存在安全隐患。本文提出了一种改进协议,解决了不法分子恶意伪造离线消息的问题,提高了协议的安全性。

Lee proposed a delegation-based authentication protocol for portable communication systems.A kind of off-line authen-tication process was presented aimed at optimizing the performance of local server on the base of on-line authentication process.But the research has shown that a few potential safety hazard still exist.In order to solve the safety problem of forging off-line information,an improved protocol is put forward in this paper,which enhanced the security performance of protocol.
