Title:
Automatic Search of Differential Path in MD4
Authors: Pierre-Alain Fouque, Gaetan Leurent, Phong Nguyen
Abstract:In 2004, Wang et al. obtained breakthrough collision attacks on the main hash functions from the MD4 family. The attacks are differential attacks in which one closely follows the inner steps of the underlying compression function, based on a so-called differential path. It is generally assumed that such differential paths were found ``by hand’'. In this paper, we present an algorithm which automatically finds suitable differential paths, in the case of MD4. As a first application, we obtain new differential paths for MD4, which improve upon previously known MD4 differential paths. This algorithm could be used to find new differential paths, and to build new attacks against MD4.
