Abstract

In this paper, we cryptanalyze the compression functions of MD4, MD5 and 4-, 5-pass HAVAL in encryption mode. We exploit the recently proposed related-key rectangle and boomerang techniques to show non-randomness of MD4, MD5 and 4-, 5-pass HAVAL and to distinguish them from a randomly chosen cipher. The attacks are highly practical and have been confirmed by our experiments.
