Abstract

Se proporciona un aparato para autenticar la informacion utilizando una funcion de eleccion arbitraria de elementos de doble correccion anticipante para proporcionar complementacion en la implementacion de un algoritmo de encripcion. Un procesador criptográfico tiene una primera entrada para recibir texto sencillo, una segunda entrada para recibir una clave y una salida para emitir texto codificado generado al procesar de manera criptográfica el texto sencillo y la clave. Un primer elemento de circuito responde al texto codificado y al texto sencillo para emitir un primer derivado de texto codificado. Un segundo elemento de circuito responde a cuando menos una porcion del primer derivado de texto codificado y la clave para emitir un segundo derivado de texto codificado. El primer y segundo elementos de circuito pueden ser compuertas de XOR. De manera alternativa, estos elementos pueden proporcionarse utilizando tablas de busqueda. Pueden proporcionarse etapas de procesador criptográfico subsecuentes que tiene una primera entrada para recibir un segundo texto sencillo, una segunda entrada para recibir el segundo derivado de texto codificado como una clave, y una salida para emitir el segundo texto codificado generado al procesar de manera criptográfica el segundo texto sencillo y el segundo derivado de texto codificado. En una modalidad ilustrada, el procesador criptográfico es un procesador de los DES.
