Abstract

La presente se refiere a una solucion para administrar el cifrado de mensajes de control en una red de telecomunicaciones inalámbrica. La generacion de la clave se basa en numeros de secuencia y la presente reduce el acceso a los dispositivos de la red del nucleo para actualizar numeros de secuencia que se refieren a eventos de la red al separar la generacion de numeros de secuencia a diferentes partes de la red y diferentes tipos de eventos de la red. Esto se hace al proveer una solucion donde los eventos de seguimiento de los numeros de secuencia y los eventos de transferencia están separados entre sí en proveer entrada al cifrado mensaje de control de recursos de radio. Se pueden usar tres contadores diferentes para diferentes tipos de eventos y los tres pueden ser usados como entrada a un algoritmo de cifrado.
