Abstract

Se proporciona una criptografía simétrica para encriptar y desencriptar información, que puede implementarse eficientemente en hardware o en software. La criptografía simétrica utiliza un generador de claves, de manera tal que la criptografía no es dependiente de una sola clave de criptografía estática. El generador de claves es un valor o conjunto de valores a partir de los cuales se genera la clave. El generador de claves incrementa significativamente la complejidad de cálculo del criptoanálisis diferencial y otros ataques criptográficos. En una modalidad, el generador de claves se actualiza con funciones unidireccionales que presentan el efecto de avalancha, el cual genera una secuencia imprevisible de claves utilizadas durante el proceso de encriptación o desencriptación. En una modalidad, la actualización del generador de claves ayuda a crear una secuencia de permutaciones imprevisibles que difunde la información a través de uno o más bloques. En una modalidad, un generador de claves diferente ayuda a crear una secuencia de permutaciones imprevisibles que actúan como una serie de cajas de sustitución.
