Abstract:
Security key stream generation in a communication apparatus. The method includes using a count parameter and a bearer parameter as input, value of said count parameter being incremented as security key streams are generated and value of the count parameter having a finite maximum value; detecting value of the count parameter reaching a predetermined value; and responsive to the detecting, changing value of the bearer parameter into a new value, and resetting value of the count parameter to a value below the maximum value.
