ABSTRACT:
In a communication system, an authentication ciphering offset (ACO) is generated as a function of one or more parameters, wherein at least one of the one or more parameters is derived from earlier-computed values of the ACO. This enables each device to avoid generating an ACO value that is out of synchronization with a counterpart ACO value generated in another communication device.
