Abstract

Existen metodos para determinar la o las claves utilizadas por el modulo que analiza los datos que entran o salen de el en el momento de la utilizacion del modulo de encriptacion-desencriptacion. Para paliar este defecto, el metodo multi-modulos propuesto consiste en que el modulo corriente abajo comience sus operaciones para encriptar-desencriptar cuando este disponible una parte de los resultados del modulo corriente arriba.
