Redundancy of the Wang-Yu Sufficient Conditions

Yuto Nakano, Hidenori Kuwakado, and Masakatu Morii

Abstract

Wang and Yu showed that MD5 was not collision-resistant, but it is known that their sufficient conditions for finding a collision of MD5 includes some mistakes. In this paper, we examine the sufficient conditions by computer simulation. We show that the Wang-Yu conditions include 16 unnecessary conditions for making a collision. Sasaki et al. claimed that modifying one condition made it possible to remove eleven conditions. However, the result of our computer simulation shows that their conditions does not make a collision.
