An ad hoc network includes a first node, a second node, and a third node. The first node and second node share a first shared secret key, and the first node and third node share a second shared secret key. The second node and third node share a temporal key. The first node generates a unique key, encrypts the unique key with a first shared secret key to generate a first encrypted unique key and transmits the first encrypted unique key to the second node. The first node encrypts the unique key with a second shared secret key to generate a second encrypted unique key and transmits the second encrypted unique key to the third node. To establish the temporal key, the second node decrypts the first encrypted unique key and the third node decrypts the second encrypted unique key thereby each generating the unique key. |
