| Abstract(in English) | 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. |
