Title:
Flaws in Differential Cryptanalysis of Reduced Round PRESENT

Authors: Manoj Kumar, Pratibha Yadav, Meena Kumari

Abstract:

In this paper, we have presented flaws in differential cryptanalysis of reduced round variant of PRESENT given by M.Wang in [3] [4] for 80 bits key length and we have shown that it is not possible to recover 32 subkey bits by differential cryptanalysis of 16-round PRESENT as claimed in [3] [4].We have also shown that at the most 30 subkey bits can be recovered by the attack given in [4] after some modifications in the algorithm presented in [3][4].
