Abstract
SISTEMA CRIPTOGRAFICO. EL SISTEMA CRIPTOGRAFICO OBJETO DE LA INVENCION TIENE POR FINALIDAD OFRECER LA MAXIMA FLEXIBILIDAD EN EL ENTORNO DE REDES DE ORDENADORES Y ESTACIONES DE TRABAJO MEDIANTE LA UTILIZACION DE ALGORITMOS DE CLAVE PUBLICA Y PRIVADA COMO MEDIDAS DE ENCRIPTACION EN SERVICIOS DE CONFIDENCIALIDAD Y AUTENTIFICACION DE LA INFORMACION, FIRMAS DIGITALES Y DISTRIBUCION DE CLAVES. EL SISTEMA ESTA CONSTITUIDO POR UNA TARJETA CRIPTOGRAFICA (1), EN ASOCIACION FUNCIONAL CON UNA UNIDAD DE PROCESO DE DATOS (2) Y UNA RED DE COMUNICACIONES (3), CON LA POSIBILIDAD DE CONEXION A UN PERIFERICO (4) TIPO MODEM, LECTOR DE TARJETAS INTELIGENTES, ETC., CON LA PARTICULARIDAD DE QUE LA CITADA TARJETA CRIPTOGRAFICA (1) SE INSTALA EN UNO DE LOS ALOJAMIENTOS DISPONIBLES A TAL EFECTO EN EL INTERIOR DE LOS ORDENADORES, SIN QUE ESTA AFECTE A LA OPERATIVIDAD NORMAL DEL MISMO.
