Abstract
A technique for mitigating excessive operations attacks in a wireless communication network includes receiving message requests from stations, detecting an excessive operation attack, checking if a received request is a first request or a retry request, and ignoring any first requests. The method can also include saving information about the first request, and wherein if checking reveals that the received request is a retry request, the method further confirms that the retry request and the saved information about the first request meet matching conditions, whereupon the retry request is further processed as normal. Since attacks rarely utilize retry requests, this technique effectively ignores attack messages.
