Sufficient conditions for finding the collision pairs of MD5 are about
600 conditions on internal variables, but the necessity of the
conditions has not been studied. We investigate their necessity by a
computer simulation, that is, check 1724 pairs of collision messages
generated with the collision finding algorithm. As a result, we found
that seven conditions are unnecessary. We also show the reason that
three conditions of them are unnecessary. The theoretical analysis on
the remaining four conditions is a future work. |
