An Improved Attack on WG Stream Cipher
WG is a synchronous stream cipher submitted to the hardware profile of eSTREAM project. The main feature of this stream cipher is the use of WG transformation. WG uses keys and initial vectors (IVs) of the same lengths 80, 96, 112 and 128 bits. Moreover, IVs of the length 32 and 64 bits are admitted. The most important key recovery attack on WG was presented by Wu and Preneel and uses the weakn...
متن کاملA Stream Cipher Based on Chaotic Permutations
In this paper we introduce a word-based stream cipher consisting of a chaotic part operating as a chaotic permutation and a linear part, both of which designed on a finite field. We will show that this system can operate in both synchronized and self-synchronized modes. More specifically, we show that in the self-synchronized mode the stream cipher has a receiver operating as an unknown input o...
متن کاملA New Attack on the LEX Stream Cipher
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, was selected to phase 3 of the eSTREAM competition. The suggested methodology seemed promising, and LEX, due to its elegance, simplicity and performance was expected to be selected to the eSTREAM portfolio. In this paper we s...
متن کاملDivide and Conquer Attack on ABC Stream Cipher
Abstract ABC is a synchronous stream proposed as a candidate to ECRYPT Project. ABC gets a 128-bit key and a 128-bit IV and produces 1195 bits as the internal state of the cipher. Using some statistical simulations we show that one of the ABC components, a key-IV dependent function over GF(2) called C which is chosen randomly from a family of functions, is slightly better than a randomly chosen...
متن کاملThe Cube Attack on Stream Cipher Trivium and Quadraticity Tests
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 Trivium and Grain128, reduced variants of the block ciphers Serpent and CTC and to a reduced version of the keyed hash function MD6. Independently a very similar attack named AIDA was introduced by M. Vielhaber. In this...
