Abstract
Un método y un dispositivo asociado para obtener un valor aleatorio de referencia a partir de una senal de paginación transmitida entre una estaciónde red y una terminal de usuario de un sistema de comunicaciones radiotelefónicas, tal como unsistema de comunicaciones celular satelital.Cuando se ha de iniciar la comunicación, una estación de red transmite una senal de paginación a una terminal de usuario. Cuando la terminal deusuario detecta la senal de paginación, s e obtieneun valor aleatorio de referencia a partir de una porción de la senal de paginación, y se generay se transmite a la estación de red una senal de respuesta correspondiente al valor aleatorio de referencia. Cuando la estación de re d recibela senal derespuesta, la compara con un valor de respuesta esperado para autenticar la terminal de usuario.
