Abstract:

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 262.92, 266.20and 2119respectively. The results show that the attack was better than results before on the number of round and time complexity.

Key words: cryptanalysis, bock cipher, integral attack, HIGHT block cipher
