A method and system for propagating mutual authentication data in both a first wireless communication network and a second wireless communication network is useful for unifying wireless communication networks. The method includes mutually authenticating a first node operating in the first network and a second node operating in the second network (step 205). A unification message is then transmitted from the first node to a third node operating in the second network, where the unification message indicates that the first node is authenticated with the second network (step 210). In response to the unification message, authentication messages from the third node and the second node are then relayed through the first node, for mutually authenticating the third node and the second node (step 215).
