摘要

针对无线局域网(WLAN)802.1X协议易受重放、拒绝服务等攻击的问题

采用非形式化方法

根据攻击者的能力

从攻击者扮演的协议角色

即模仿正常的协议行为和破坏正常的通信出发

分析了802.1X协议的安全性

并对攻击行为进行了分类

据此提出了一种基于攻击的无线局域网主动测试方法.通过构造协议报文序列、模拟攻击者的攻击行为对协议运行主体进行攻击

从而判断协议是否存在安全漏洞.测试结果表明

所提方法有效地结合了攻击者和测试者的特点

在一定程度上覆盖了针对802.1X协议的已知安全漏洞

并具有发现潜在问题的能力.

Abstract

Aimed at the problem that the vulnerable wireless local area network(WLAN)802.1X protocol is not susceptible to replay and DoS(denial of service)attacks

etc

an informal method is introduced to analyze the security properties of 802.1X protocol. The method classifies attack behaviors according to the ability of attackers

and from the aspect of the role which attackers can play in the protocols(i.e.

imitating normal protocol behavior or breaking normal communication). Then a new method

WLAN active testing

is proposed. Attacks to the protocol running mainbody are implemented by simulating the actions of the attacker which can be used to make up protocol messages. The results are used to determine whether the protocol security vulnerabilities exist or not. Testing results show that the method combines characteristics of both the attacker and the tester to cover some known protocol security vulnerabilities

and has the ability to reveal some potential problems.
