Abstract

Se establece una clave de seguridad, K_eNB, para proteger el tráfico de RRC/UP entre un UE (User Equipment, Equipo Usuario), (II) y un eNodeB sirviente (12), mediante un método y una disposicion en un MME (Mobility Management Entity, Entidad Administradora de la Movilidad) (13), MME, y en dicho UE (II), de un EPS (Evolved Packet System, Sistema Evolucionado de Paquetes). El MME y el UE deriva la clave de seguridad, K_eNB, a partir de al menos un numero de secuencia de enlace ascendente de NAS, NAS_U_SEQ, enviado desde el UE al MME, y a partir de una clave de la Entidad de Administracion de la Seguridad del Acceso (Security Management Entity-key), K_ASME, compartida entre el MME y el UE.
