Paper: Testing Randomness in Ciphertext of Block-Ciphers Using DieHard Tests

ABSTRACT One of the important aspects of the security of block ciphers is the randomness of the cipher text. One criterion used to evaluate the Advanced Encryption Standard (AES) candidate algorithms was their demonstrated suitability as random number generators. In this paper, we introduced a new approach to interpret the results of tests of randomness.… Read More »

Paper: DES96 – Improved DES Security

ABSTRACT The Data Encryption Standard (DES) has shown noticeable signs of aging during the last two decades. In this paper we develop a system that is a DES-variant with more resistance towards the possible attacks against DES. The developed system has a sub-key generation algorithm that is completely different from the original DES. The developed… Read More »
