Abstract

EN UN PROCEDIMIENTO PARA PROPORCIONAR UNA COMUNICACION SEGURA ENTRE DOS DISPOSITIVOS, UN PRIMER DISPOSITIVO GENERA UNA CLAVE ALEATORIA (CI) Y TRANSFIERE ESTA CLAVE A UN SEGUNDO DISPOSITIVO DE UN PRIMER MENSAJE CODIFICADO CON EL USO DE UNA CLAVE PUBLICA. EL SEGUNDO DISPOSITIVO DECODIFICA EL PRIMER MENSAJE CODIFICADO POR MEDIO DE UNA CLAVE SECRETA CORRESPONDIENTE A FIN DE OBTENER LA CLAVE ALEATORIA (CI) Y ESTA CLAVE ALEATORIA SE UTILIZA PARA CODIFICAR Y DECODIFICAR TODAS LAS TRANSMISIONES ENTRE ESTOS DISPOSITIVOS. EN UN DECODIFICADOR PARA UN SISTEMA DE TV DE PAGO, QUE COMPRENDE UN MODULO DE ACCESO CONDICIONADO Y UNA TARJETA INTELIGENTE, ESTE PROCEDIMIENTO SE APLICA A FIN DE PROPORCIONAR UNA COMUNICACION SEGURA ENTRE EL MODULO DE ACCESO AL CONTROL Y LA TARJETA INTELIGENTE Y/O ENTRE EL DECODIFICADOR Y EL MODULO DE ACCESO CONDICIONADO.
