Abstract. In 2002, algebraic attacks using overdefined systems of equations have been proposed as a potentially very powerful cryptanalysis technique against block ciphers. However...
Abstract. In [6], Biryukov presented a new methodology of stream cipher design, called leak extraction. The stream cipher LEX, based on this methodology and on the AES block cipher...
Abstract. In this paper we compare systems of multivariate polynomials, which completely define the block ciphers Khazad, Misty1, Kasumi, Camellia, Rijndael and Serpent in the vie...
Most last-round attacks on iterated block ciphers provide some design criteria for the round function. Here, we focus on the links between the underlying properties. Most notably, ...
The AES block cipher has a 128-bit block length and a user key of 128, 192 or 256 bits, released by NIST for data encryption in the USA; it became an ISO international standard in ...
