Abstract
In one embodiment, multiple keys are generated in user equipment of a communication system based at least in part on a designated key expansion multiplier. A key identifier is received in the user equipment from a base station of the communication system. The user equipment selects a particular one of the keys as a function of the received key identifier, and utilizes the selected one of the keys to secure data sent from the user equipment to the base station. For example, the keys may comprise respective portions of a key stream generated by the user equipment responsive to a message received from the base station, with the keys being shared by the user equipment and the base station through independent generation of the key stream in the base station. The base station may illustratively comprise an evolved Node B (eNB) of an Evolved Universal Terrestrial Radio Access Network (E-UTRAN).
