Rectified Differential Cryptanalysis of 16 round Present
In this paper, we have suggested rectifications in differential cryptanalysis of ultra-lightweight block cipher PRESENT reduced to 16 rounds. We have shown that proposed differential attack by Wang [3] on 16 round PRESENT can recover at the most 30 subkey bits, although the author has claimed to recover 32 bits of subkey for last two rounds. We have also computed data complexity and success pro...
متن کاملDifferential Cryptanalysis of the Full 16-Round DES
In this paper we develop the first known attack which is capable of breaking the full 16 round DES in less than the complexity of exhaustive search. The da ta analysis phase computes the key by analyzing about 2% ciphertexts in 237 time. The 2% usable ciphertexts are obtained during the data collection phase from a larger pool of 247 chosen plaintexts by a simple bit repetition criteria which d...

of n, if p > 2 ?40:2 then the number of analyzed plaintexts is two and the complexity of the data analysis phase is 2 32. However, using about four times as many chosen plaintexts, we can use the clique algorithm (described in 1]) and reduce the time complexity of the data analysis phase to less than a second on a personal computer. The known plaintext attacks need about 2 32 p ?0:5 known plain...
متن کاملFlaws in Differential Cryptanalysis of Reduced Round PRESENT
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 s...
متن کاملDifferential Cryptanalysis of PRESENT
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 ≤ r ≤ 15), then give the differential cryptanalysis on reduced-round variants of PRESENT. We attack 16-round PRESENT using 2 chosen plaintexts, 2 6-bit counters, and 2 memory accesses.
