Abstract
Method for detecting an attack on a broadcast key shared between an access point and its wireless clients. Upon detection of the attack, actions are implemented to react to the attack as defined in one or more security policies. Detection of the attack is achieved by examining both a link message integrity check and an infrastructure management frame protection (IMFP) message integrity check contained in a broadcast management frame.
