Flaws in Differential Cryptanalysis of Reduced Round PRESENT

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