Abstract

LA INVENCION SE REFIERE A LOS CIRCUITOS Y PROCESOS DE ENCRIPTADO, PARTICULARMENTE PARA TARJETAS DE MICROCHIP. PARA REALIZAR DE MANERA MUY SIMPLE UNA AUTENTIFICACION DE TARJETAS DE MEMORIA QUE NO COMPRENDEN MICROPROCESADOR, SE UTILIZA UN ENCRIPTADO MEDIANTE UNA TABLA DE DATOS SECRETOS DE LA TARJETA, TABLA SOBRE LA QUE SE EJECUTAN LOS CICLOS RECURRENTES; A CADA CICLO SE LEE EN LA TABLA UNA PALABRA SITUADA EN UNA DIRECCION DEFINIDA EN PARTE POR A PALABRA LEIDA EN EL CICLO PRECEDENTE. LA NUEVA DIRECCION ESTA PREFERENTEMENTE CONSTITUIDA POR VARIOS BITS DE LA PALABRA PRECEDENTE Y POR UN BIT PROCEDENTE BIEN DE UN DATO INTERNO DE LA TARJETA, BIEN POR UN DATO EXTERNO ENVIADO POR UN LECTOR DE TARJETAS, BIEN TODAVIA POR UN REGISTRO QUE CONTIENE YA UN RESULTADO DE ENCRIPTADO PARCIAL.
