| Summary: | The security of HIGHT block cipher under integral attack was studied. Firstly, the flaw in the existing results on building the distinguisher was corrected. And a new 11-round integral distinguisher of HIGHT was built. Based on this new distinguisher, a 17-round multiple-integral distinguisher was built. By using the 17-round distinguisher, 25-round in-tegral attack on HIGHT was proposed based on the principle of time memory trade-off, with the data, time and memory complexity of 2<sup>62.92</sup>, 2<sup>66.20</sup>and 2<sup>119</sup>respectively. The results show that the attack was better than results before on the number of round and time complexity. |
