Abstract:
A method of key distribution includes generating, by a first system device (101), key material and forwarding the key material from the first system device (101) to a second system device (107). It is determined whether a mobile station (401), for which the key material is directed, is active on the system. When the mobile station is active, the key material is forwarded to a base station (115) where the mobile station (401) is active, and the base station (115) forwards the key material to the mobile station (401).

Abstract:
A method includes receiving an authentication request from a mobile station (401) and determining whether to forward the request to an authentication agent. When it is determined to forward the request, the request is forwarded to the authentication agent (107). A random number and a random seed are received from the authentication agent (107). The random number and the random seed are forwarded to the mobile station (401). A response to the random number and the random seed from the mobile station (401) is received and forwarded to the authentication agent (107). The authentication agent (107) compares the response with an expected response. When the authentication agent (107) authenticates the mobile station (401), a derived cipher key is received from the authentication agent (107).
Abstract:
Un método que comprende las etapas de: generar, por un primer dispositivo del sistema (101), una primera clave de cifrado (GCK) asociada con el cifrado del tráfico para comunicaciones de grupo; dirigir la primera clave de cifrado (GCK) desde el primer dispositivo del sistema (101) a un segundo dispositivo del sistema (107, 121) distinto que una estación móvil; almacenar la primera clave de cifrado (GCK) en el segundo dispositivo del sistema (107, 121), caracterizado por generar, por el segundo dispositivo del sistema (107, 121), una segunda clave de cifrado (MGCK) asociada con el cifrado del tráfico para comunicaciones de grupo combinando la primera clave de cifrado (GCK) con una tercera clave de cifrado (CCK); y dirigir la segunda clave de cifrado (MGCK) a un tercer dispositivo del sistema (115, 117, 129, 131) distinto que una estación móvil y distinto que los dispositivos del sistema primero y segundo.
Abstract:
Un método que comprende las etapas de: generar un número aleatorio, una respuesta esperada, y una clave de cifrado derivada asociada con la seguridad de las comunicaciones de la interfaz aire con una estación móvil (401, 403, 405); dirigir el número aleatorio y una semilla aleatoria a la estación base (115, 117) que está localizada en una primera pila de dispositivos, en el que la primera pila está asociada con una intra-clave para cifrar el material de claves que se distribuye dentro de la primera pila; recibir, desde la estación base (115, 117), una respuesta al número aleatorio y a la semilla aleatoria; comparar la respuesta y la respuesta esperada; y cuando la respuesta coincide con la respuesta esperada, cifrar la clave de cifrado derivada usando la intra-clave y dirigir la clave de cifrado derivada cifrada a las estaciones base (115, 117).
