Abstract

La presente invención se refiere a métodos y aparatos para administración de contexto de seguridad flexible durante cambios de AMF. Un aspecto de la invención es un mecanismo para lograr la seguridad hacia atrás durante los cambios de AMF. En lugar de pasar la clave de NAS actual a la AMF de destino, la AMF de origen deriva una nueva clave de NAS, proporciona la nueva clave de NAS a la AMF de destino, y envía una indicación de cambio de clave al UE, ya sea directamente o a través de algún otro nodo de red. El UE puede entonces derivar la nueva clave de NAS de la antigua clave de NAS. En algunas modalidades, la AMF puede proporcionar un parámetro de generación de clave al UE para usarlo en la derivación de la nueva clave de NAS. En otras modalidades, la AMF de destino puede cambiar uno o más algoritmos de seguridad.
