Abstract

Existen métodos para determinar la o las claves utilizadas por el modulo que analiza los datos que entran o salen de él en el momento de la utilizacion delmodulo de encriptacion-desencriptacion. Para paliar este defecto, el método multi-modulospropu esto consiste en que el modulo corriente abajo comience susoperaciones para encriptar-desencriptar cuando esté disponible una parte de los resultados del modulo corriente arriba.
