Randomizing encryption mode
Yi‐Shiung Yeh, I-Te Chen, Chan-Chi Wang · Journal of Discrete Mathematical Sciences and Cryptography · 2005
We investigate the mode of block cipher encryption which a random number is added into the process of an encryption. Many manners to add a random number are examined for the capabilities to defeat brute-force, differential and linear attacks. Then, we claim that if the underlying block cipher withstand brute-force attack, some manners will be secure even though the underlying block cipher is vulnerable to differential and linear attacks.
