无线局域网安全策略分析与应用研究

Research on the Analysis and Application of the Security Strategies of Wireless Local Area Network

无线局域网以无线介质在自由空间传送数据,相比有线网络更加方便,但是安全性面临更大风险,为保障数据机密性、可认证和完整性,防范未知的攻击风险,应当采用适当的安全保障措施。本文认真分析安全加密算法、安全加密协议以及不同的安全策略,比较WEP、WPA和WPA2应用场景,分析WPA2安全策略的认证和加密流程,给出相应安全策略的配置命令,为用户实施无线局域网安全保护提供理论和实际应用指导,对无线局域网安全保障实施具有一定的指导意义和应用价值。

WLAN(wireless local area network)transmits data in free space by wireless medium,which is more convenient than wired network,but the security is facing greater risks.In order to guarantee data confidentiality,authentication and integrity,and to guard against unknown attack risks,appropriate security measures should be used in practical applications.This paper analyzes the security encryption algorithm,security encryption protocol and different security strategies in detail,and compares the application scenarios of WEP,WPA and WPA2.The authentication process and encryption process of WPA2 security policy are analyzed,and the configuration commands are given.This paper provides theoretical and practical guidance for users to implement WLAN security protection,and has certain guiding significance and application value for the implementation of WLAN security protection.
