Abstract:
1. A method, comprising: receiving, by an access point (AP) after distribution of a pairwise master key, a probe request; transmiting, by the AP, in response to the probe request, a probe response including an AP nonce generated by the AP; and receiving, by the AP, a pairwise master key request information element as a reassociate request from a user station that received the transmitted AP nonce, the pairwise master key request information element including the AP nonce, a user station nonce, and a message integrity code, wherein the message integrity code was computed using a message integrity code algorithm with a key confirmation key, the AP nonce, and the user station nonce, and wherein the key confirmation key was computed using a psuedo-random function algorithm with the pairwise master key, a media access control address of the AP, and a media access control address of the user station.
