Abstract

Un sistema de seguridad o protección (2) que comprende: una pluralidad de divisiones (6, 8, 10) de primeras señales; una pluralidad de subsistemas de seguridad o protección (12, 14, 16) cada uno de los cuales recibe una división correspondiente de las mencionadas divisiones de las primeras señales y produce una pluralidad correspondiente de segundas señales (17A-C) de los mismos; caracterizado porque: cada subsistema de seguridad o protección comprende medios de memoria reflexiva (68) para comunicar las segundas señales entre ese subsistema de seguridad o protección y otro de los subsistemas de seguridad o protección; y porque el medio de memoria reflexiva de cada subsistema está adaptado para almacenar las representaciones de la segunda señal a partir de la división de las primeras señales que recibe y de al menos otra segunda señal, de otro de los subsistemas de seguridad o protección, derivada de la correspondiente división de las primeras señales que este otro mencionado subsistema de seguridad o protección recibe.
