基于策略的高校自调节无线网络安全模型研究

Policy-Based Universities Self-Regulation Wireless Network Security Model Study

本文先简要阐述无线网络的定义、安全隐患及一般安全技术。为了确保无线网络的安全，详细介绍了无线网络的802．11系列安全机制，并介绍了增强的安全机制802．1X。在对数据传输的研究中，对WEP加密解密算法进行深入研究，并在对RC4算法的分析中，发现弱密钥的安全隐患，同时提出了改进策略。

First of all,this paper describes the defmition,security risks and general security technology in wireless network briefly.In order to ensure the security of wireless network,this thesis demonstrates the series of security mechanisms in wireless network named 802.11 and enhanced security mechanisms called 802.IX.In the research on data transmission,the algorithms of WEP encryption,decryption and RC4 are analyzed in order.Improvement strategies are proposed after weak security key risks are found.
