PRESENT is an ultra-lightweight block cipher, proposed by A.Bogdanov et al. in CHES 2007 for extremely constrained environments such as RFID tags and sensor networks. Differential attack against 16 round PRESENT was given by Wang using 264 chosen plaintexts, 232 6- bit counters and 264 memory accesses and it was claimed to recover 32 sub-key bits by differential attack on 16 round PRESENT. In this paper, the authors have suggested rectifications in differential cryptanalysis of ultra-lightweight block cipher PRESENT reduced to 16 rounds.
