ABSTRACT:
A system is provided in which a client/server
etwork can implement a key management session when the server initiates the key management session utilizing a nonce. The nonce allows a wakeup or trigger message to be conveyed to the client such that a service attack on the server can be avoided when a false nonce is received by the server with an AP request message. Thus the server can disregard AP request messages that are not accompanied by a nonce stored by the server. The method can be implemented through circuitry, electrical signals and code to accomplish the acts described in the method.
