title = "Linear cryptanalysis on SPECTR-H64 with higher order differential property",
abstract = "In this paper, we find linear equations of SPECTR-H64 using the property of controlled permutation boxes. Also, we construct the fourth-order differential structure using the property that the algebraic degree of the function G is 3, which is the only non-linear part of SPECTR-H64. These linear equations and structures enable us to attack the reduced 6 round SPECTR-H64. So, we can recover the 6-th round subkey with about 244 chosen plaintexts and 2229.6 steps which are lower than the exhaustive search 2256.",
