Abstract

Métodos y aparatos para la gestión de contexto de seguridad flexible durante los cambios de AMF. Además un mecanismo para lograr la seguridad con versiones previas durante los cambios de AMF en modo inactivo. En lugar de pasar la clave NAS actual a la AMF diana, la AMF fuente deriva una nueva clave NAS, proporciona la nueva clave NAS a la AMF diana, junto con una indicación de cambio de clave que indica que la clave NAS se ha cambiado. La AMF diana envía la indicación de cambio de clave al equipo de usuario.
