摘要: 提出一种新的无线局域网认证密钥协商协议,可以提供双方相互认证及密钥确认。该协议在密钥设置上基于挑战响应协议和KAS方案,在密钥预分配上基于Diffie-Hellman协议,可以提供完美前向安全性,抵抗被动攻击、字典攻击、中间人攻击、假冒攻击等。并对协议的计算代价和通信代价进行分析。

Abstract: This paper puts forward a new authenticated key agreement protocol for Wireless Local Area Network(WLAN), which provides secure mutual authentication, key establishment and key confirmation. It can resist dictionary attacks by either passive or active networks intruder, man-in-the middle attack, and impersonate attack. It also offers perfect forward secrecy. The protocol combines techniques of challenge response protocols with symmetric key agreement protocols. Both computational and communication performance are analyzed.

Key words: key agreement protocol, Wireless Local Area Network(WLAN), challenge response protocol
