Research on Wireless Local Area Network Security

分析了现有的无线局域网(WLAN)标准IEEE 802,11 b的WEP安全机制及其在加密和认证上的漏洞,SPRNG协议用同步伪随机码发生器产生认证变量,并为每帧数据加密,是基于双向认证和加密,并分析了其实现技术的复杂性和安全性。

This paper analyzes WEP (Wired Equivalent Privacy) in IEEE 802.11 WLAN stan- dard and its weakness on encryption and authentication. SPRNG uses synchronized pseudo random number generation to generate authenticator variables and fresh encryption keys per frame. In this paper, the implementation complexity and security of the protocol based on mutual authentication and encryption is presented.
