基于802.11的无线接入网络的便利性已经在消费者、工业和军事部门得到了广泛的部署。但是，这种使用是基于隐式的保密性和可用性假设。虽然802.11基本保密机制中的安全漏洞已被广泛宣传，但对网络可用性的威胁却远没有得到广泛的重视。事实上，有人建议802.11非常容易受到针对其管理和媒体访问协议的恶意拒绝服务（DoS）攻击。本文提供了对这种802.11特定攻击的实验分析——它们的实用性、有效性和潜在的低开销实现变化，以减轻潜在的漏洞。
The convenience of 802.11-based wireless access networks has led to widespread deployment in the consumer, industrial and military sectors. However, this use is predicated on an implicit assumption of confidentiality and availability. While the security flaws in 802.11’s basic confidentially mechanisms have been widely publicized, the threats to network availability are far less widely appreciated. In fact, it has been suggested that 802.11 is highly susceptible to malicious denial-of-service (DoS) attacks targeting its management and media access protocols. This paper provides an experimental analysis of such 802.11-specific attacks – their practicality, their efficacy and potential low-overhead implementation changes to mitigate the underlying vulnerabilities.
