Algebraic Cryptanalysis of the Data Encryption Standard
In spite of growing importance of AES, the Data Encryption Standard is by no means obsolete. DES has never been broken from the practical point of view. The triple DES is believed ...

On the Twofish Key Schedule
Twofish is a new block cipher with a 128 bit block, and a key length of 128, 192, or 256 bits, which has been submitted as an AES candidate. In this paper, we briefly review the st...

Cube Attacks on Tweakable Black Box Polynomials
Almost any cryptographic scheme can be described by tweakable polynomials over GF(2), which contain both secret variables (e.g., key bits) and public variables (e.g., plaintext bit...

Algebraic Side-Channel Attacks on the AES: Why Time also Matters in DPA
Algebraic side-channel attacks have been recently introduced as a powerful cryptanalysis technique against block ciphers. These attacks represent both a target algorithm and its ph...
