Abstract

Sistema y método aleatorizador-encriptador autocorrector tal que suministradas secuencia de datos de entrada (X) y bloque de control (K), genera siempre secuencia de datos aleatorizados-encriptados (A) que es secuencia de números aleatorios. El generador-ensamblador de firma (601) con secuencia de datos (X) genera secuencia de texto claro firmado (XF) suministrada a aleatorizador-encriptador (102) donde es agrupada con bloque de control candidato (KC), generado por generador de bloques de control candidatos (801) a partir de bloque de control (K), generando secuencia de texto aleatorizado-encriptado propuesta (AP) suministrada a verificador de aleatoriedad (603) que valida aleatorización de la secuencia. Si secuencia de texto aleatorizado-encriptado propuesta (AP) es aleatoria se suministra como secuencia de texto aleatorizado-encriptado (A); si no es aleatoria, el generador de bloques de control candidatos (801) genera nuevo bloque de control candidato (KC) para aleatorizar-encriptar de nuevo la secuencia de texto claro firmado (XF). La iteración se repite hasta que se genera secuencia de texto aleatorizado-encriptado propuesta (AP) aleatoria.
