Abstract

La presente invencion se refiere a un método para procesar una señal digital de dimension k, en uno de los llamados sistemas de comunicacion de seguridad, tal que, la señal (y) digital a la salida, no pueda ser deducida de la señal (x) digital en la entrada, que consiste en despachar la señal (x) digital a un dispositivo que efectua una funcion de una vía. El método incluye las siguientes etapas: - despachar la señal (x) digital de la entrada a un circuito C (1, 2) que da como salida una señal (x") digital de dimension n aceptable a la funcion de una vía; - despachar la señal (x") de circuito C (1, 2) al circuito que efectua la funcion de una vía para dar como salida la señal (y) digital. La invencion se aplica en particular a los llamados sistemas de conmutacion de seguridad. Figura 2.
