Crossword Puzzle Attack on NLSsful on 90.3% of . among 2. possible values. We extend the CP attack to NLSv2 which is a tweaked version of NLS. In result, we build a distinguisher which has the bias of around 2.. Even though this attack is below the eSTREAM criteria (2.), the security margin of NLSv2 seems to be too low.

Improved DST Cryptanalysis of IDEA significantly in performance. The improvements presented reduce the attack’s plaintext, memory, precomputation time, and key search time complexities. These improvements also make a practical implementation of the attack on reduced versions of IDEA possible, enabling the first experimental verifica

Related-Key Rectangle Attack on the Full SHACAL-1ect and was accepted as a finalist for the 2nd phase of the evaluation..In this paper we devise the first known attack on the full 80-round SHACAL-1 faster than exhaustive key search. The related-key differentials used in the attack are based on transformation of the collision-producing differential

Cryptanalysis of Achterbahn-Version 2on, denoted Achterbahn-Version 2, was proposed. This paper demonstrates an attack on this second version. In the attack, a quadratic approximation of the output function is considered. The attack uses less keystream bits than the upper limit given by the designers and the computational complexity is

Cryptanalysis of the Stream Cipher ABC v2 are about 2. weak keys in ABC v2. The complexity to identify a weak key and to recover the internal state of a weak key is low: identifying one weak key from about 2. random keys requires 6460 keystream bytes and 2. operations for each random key. Recovering the internal state of a weak key require

Efficient Implementations of Multivariate Quadratic Systemsquations appear in several multivariate cryptosystems such as the signature schemes ., Rainbow, the encryption scheme .., or the stream cipher .. We describe various implementation strategies. These strategies were combined to implement the public computations of three asymmetric schemes as well as
