Michael Klein,Birgitta König-RieseometricXL algorithm, termed the EGHAM process, also use polynomials of a much smaller degree than a Groebner basis or an XL algorithm for certain equation systems. Furthermore, the paper gives a criterion which generally makes a Groebner basis or standard XL algorithm more efficient in many cryptographic situations.

The Handbook of Environmental Chemistryear-time, quasi-constant-space integer set equality test..An interesting advantage of the proposed algorithm is its ability to compare .s without sorting them. This can prove useful when comparing very large files which are read-only or otherwise hard to sort (. on tapes, distributed across web-sites etc).

Codes as Modules over Skew Polynomial Ringsons for the Euclidean scalar product. We found new [56, 28, 15], [60,30,16], [62,31,17], [66,33,17] Euclidean self-dual skew codes and new [50,25,14], [58,29,16] Hermitian self-dual skew codes over .., improving the best known distances for self-dual codes of these lengths over ...

Bivium as a Mixed-Integer Linear Programming Problemombinatorial optimization in order to find a solution for the problem and recover the initial state of Bivium. In particular this gives us an attack on Bivium B in estimated time complexity of 2. seconds. But this kind of attack is also applicable to other cryptographic algorithms.

On Higher Weights and Code Existencerch to prove that there are exactly two inequivalent [36,8,16] codes. The technique can also be used to gain new information about the weight hierarchy of the putative [72,36,16] code, but not yet enough to say if it exists or not.

On Linear Cryptanalysis with Many Linear Approximationsn also been used to measure the entropy of the key for other statistical attacks. Moreover, we present a realistic attack on the full DES with a time complexity of 2. for 2. pairs what is a big improvement comparing to Matsui’s algorithm 2 (2.).
