Abstract

Abstract: 3G-WLAN interworking is a research hotspot now，and EAP-AKA is its authentication and key agreement protocol.This paper analyzes the protocol in detail，and modifies the vulnerability and possible attack to this protocol.With hash chain technology and CPK algorithm，this paper realizes the localized re-authentication.Finally，an analysis of the amended scheme has been made.

Key words: Wireless Local Area Network（WLAN）, Extensible Authentication Protocol-Authentication and Key Agreement（EAP-
AKA）, key agreement, re-authentication, hash chain, Combined Public Key（CPK）

摘要： 3G与WLAN互连是当前研究的一个热点，EAP-AKA是其对应的认证与密钥协商协议。详细分析该协议，修正其中的安全缺陷；并利用哈希链技术和CPK算法实现重认证本地化；最后对该改进方案进行安全性分析。

关键词: 无线局域网（WLAN）, 基于认证和密钥协商机制的可扩展认证协议（EAP-AKA）, 密钥协商, 重认证, 哈希链, 组合公钥
