—Formal methods can be used to discover obscure denial of service (DoS) vulnerabilities in wireless network protocols. The application of formal methods to the analysis of DoS vul-nerabilities in communication protocols is not a mature research area. Although several formal models have been proposed, they lack a clear and convincing demonstration of their(More)
This paper proposes a highly efficient cryptographic denial of service attack against 802.11 networks using 802.11i TKIP and CCMP. The attacker captures one frame, then modifies and transmits it twice to disrupt network access for 60 seconds. We analyze, implement and experimentally validate the attack. We also propose a robust solution and recommendations(More)
Use of intermediary hosts as stepping stones to conceal tracks is common in Internet misuse. It is therefore desirable to find a method to detect whether the originating party is using an intermediary host. Such a detection technique would allow the activation of a number of countermeasures that would neutralize the effects of misuse, and make it easier to(More)
