Methods of parallel hashing infeasible to generic attacks

Abstract

The given paper contains the analysis of modern state-of-art of hash functions and the attacks on them. As a result of the carried out analysis, it is determined that one of the most dangerous are generic attacks, based on multicollisions. To improve the infeasibility of constructions, providing paralleling a number of hashing constructions and algorithms have been suggested. Reduction functions of hashing methods on the base of these constructions are determined. Experimental research, carried out enabled to confirm the improvement of infeasibility of the given hashing method to generic attacks on the base of multicollisions.
