ABSTRACT:
In a network access point, a method of processing encrypted communication. In one embodiment, the method comprises receiving from a wireless client a first message comprising first values for a first random number and information identifying the wireless client and the access point. In one embodiment, the method further comprises generating a second message comprising second values for a second random number and information identifying the access point and the wireless client. In one embodiment, the method further comprises sending the first values and the second values to an access point server, and subsequently the access point server generates a session key using the first and second values and third values provided by the access point server, such that the processes are shared by the access point and the access point server. The method further comprises distributing the session key to the wireless client and the access point.
