Abstract
A method for encrypted communications between a first transceiver and a second transceiver is provided. The method includes sending from a first transceiver to a second transceiver a request to initiate derivation of a new encryption key. The request to initiate a new encryption key derivation includes an exchange threshold indicative of when the new encryption key is to be used to encrypt communication packets.
