Differential Cryptanalysis of PRESENT

Meiqin Wang

Abstract: PRESENT is proposed by A.Bogdanov et al. in CHES 2007 for extremely constrained environments such as RFID tags and sensor networks. In this paper, we find out the differential characteristics for r-round($5 \leq r \leq 15$), then give the differential cryptanalysis on reduced-round variants of PRESENT. We attack 16-round PRESENT using $2^{64}$ chosen plaintexts, $2^{32}$ 6-bit counters, and $2^{65}$ memory accesses.
