Block ciphers are used to encrypt data and provide data confidentiality. For interoperability reasons, it is desirable to support a variety of block ciphers efficiently. Of the bas...
Abstract. ESSENCE is a family of cryptographic hash functions, accepted to the first round of NIST's SHA-3 competition. This paper presents the first known attacks on ESSENCE....
In 2008 I. Dinur and A. Shamir presented a new type of algebraic attack on symmetric ciphers named cube attack. The method has been applied to reduced variants of stream ciphers T...
Matsui’s one-dimensional Alg. 2 can be used for recovering bits of the last round key of a block cipher. In this paper a truly multidimensional extension of Alg. 2 based on estab...
Contrarily to Kerckhoffs’ principle, many applications of today’s cryptography still adopt the security by obscurity paradigm. Furthermore, in order to rely on its proven or e...
