Multiple Differential Cryptanalysis: Theory and Practice

Céline Blondeau, Benoît Gérard

چکیده

Differential cryptanalysis is a well-known statistical attack on block ciphers. We present here a generalisation of this attack called multiple differential cryptanalysis. We study the data complexity, the time complexity and the success probability of such an attack and we experimentally validate our formulas on a reduced version of PRESENT. Finally, we propose a multiple differential cryptanalysis on 18-round PRESENT for both 80-bit and 128-bit master keys.

    Recent block ciphers have been designed to be resistant against differential cryptanalysis. Nevertheless it has been shown that such resistance claims may not be as accurate as wished due to recent advances in this field. One of the main improvements to differential cryptanalysis

    Midori is a family of SPN-based lightweight block ciphers designed to optimize the hardware energy consumption per bit during the encryption and decryption operations. At ASIACRYPT 2015, two variants of the cipher, namely Midori128 and Midori64, which support a 128-bit secret key

    Statistical analyses of multiple differential attacks are considered in this paper. Following the work of Blondeau and Gérard, the most general situation of multiple differential attack where there are no restrictions on the set of differentials is studied. We obtain closed form

    Immunity against differential cryptanalysis is an important measure in designing symmetric ciphers. Practical security is a measure to evaluate this immunity by estimating the minimum number of differential active s-boxes. A cipher with more sboxes is said to have better immunity

    Midori128 is a lightweight block cipher proposed at ASIACRYPT 2015 to achieve low energy consumption per bit. Currently, the best published impossible differential attack on Midori128 covers 10 rounds without the pre-whitening key. By exploiting the special structure of the S-box
