| Abstract: | Firstly the basic theory of differential cryptanalysis for MD4 is introduced briefly,and the detailed explanation of algorithm on the automatic search for differential path is presented.A deep study on this algorithm is made and then with the analysis of complicated relationship in some parts the original algorithm is improved.At last the truth that the new differential path generated by the improved algorithm is more effective than that generated by the original is proved. |
