基于数字签名的WLAN安全机制研究

WLAN Security Technique Based on Digital Signature

本文从WLAN安全的几个特点和要素出发,提出了一种新的基于数字签名的WLAN安全机制;该机制针对无线窃听、身份假冒和数据篡改这三个威胁WLAN的不安全因素,分为认证鉴别机制、加密传输机制和消息鉴别与完整性检测机制三个模块进行了研究。

For the main factor of the WLAN＇s security, a new WLAN Security Technique base on digital signature is presented in this thesis.This technique aims at the WLAN＇S three threats：wireless eavesdropping,counterfeiting identity and modifying data.This technique was divided into three module that certification,authentication mechanism, encryption mechanism and Message Authentication,complete examine mechanism to research.
