Abstract

Existen métodos para determinar la o las claves utilizadas por el módulo que analiza los datos que entran o salen de él en el momento de la utilización del módulo de encriptación-desencriptación. Para paliar este defecto, el método multi-módulos propuesto consiste en que el módulo corriente abajo comience sus operaciones para encriptar-desencriptar cuando esté disponible una parte de los resultados del módulo corriente arriba.
