Abstract

EL DISPOSITIVO (12) TIENE NUEVE ETAPAS DE CODIFICACION (61.1, 61.2, 69) DE LAS CUALES, LAS OCHO PRIMERAS SON IDENTICAS. TAMBIEN COMPRENDE UNA UNIDAD DE GENERACION DE BLOQUES PARCIALES DE CODIFICACION (63), UNA UNIDAD DE ENTRADA (21) Y UNA UNIDAD DE SALIDA (79). SE UTILIZA PARA LA CODIFICACION TIPO BLOQUES DE UN TEXTO SENCILLO (X) DE UNA FUENTE DE INFORMACION (11) EN UN TEXTO CODIFICADO (Y) QUE VA A SER LLEVADO A UNA LINEA DE TRANSMISION (13), PARA LO CUAL SE INTRODUCE PREVIAMENTE UN BLOQUE DE CODIGO SECRETO (Z) A TRAVES DE UN CANAL SECRETO (17). LA CODIFICACION SE LLEVA A CABO POR PASOS Y EN PARALELO PARA CUATRO BLOQUES PARCIALES (X SUB 1-X SUB 4; W SUB 11-W SUB 14; W SUB 21-W SUB 24; W SUB 81-W SUB 84; Y SUB 1-Y SUB 4) DE UNA VEZ. CON ESTE FIN, CADA ETAPA DE CODIFICACION (61.1, 61.2, 60) TIENE CUATRO PRIMERAS ENTRADAS (25-28; 35-38), SEIS O CUATRO SEGUNDAS ENTRADAS (29, 30, 32, 33, 49, 52; 129, 130, 132, 133) Y CUATRO SALIDAS (75-78). EN LAS SEGUNDAS ENTRADAS HAY UN TOTAL DE CINCUENTA Y DOS BLOQUES PARCIALES DE CODIFICACION (Z SUB 1-Z SUB 52) FORMADAS DESDE EL BLOQUE DE CODIGO (Z). EL DISPOSITIVO (12) SE PUEDE UTILIZAR TAMBIEN SIN CAMBIARLO PARA DESCODIFICAR UN TEXTO CIFRADO ENTRANTE (Y). PARA ESTO, BASTA CON APLICAR OTROS BLOQUES PARCIALES DE CODIGO A LAS SEGUNDAS ENTRADAS.
