Cryptographically strong permutations from the butterfly structure
(Journal article; Peer reviewed, 2021)Boomerang connectivity table is a new tool to characterize the vulnerability of cryptographic functions against boomerang attacks. Consequently, a cryptographic function is desired to have boomerang uniformity as low as ... -
Differentially low uniform permutations from known 4-uniform functions
(Journal article; Peer reviewed, 2021)Functions with low differential uniformity can be used in a block cipher as S-boxes since they have good resistance to differential attacks. In this paper we consider piecewise constructions for permutations with low ... -
Generalized isotopic shift construction for APN functions
(Journal article; Peer reviewed, 2021)In this work we give several generalizations of the isotopic shift construction, introduced recently by Budaghyan et al. (IEEE Trans Inform Theory 66:5299–5309, 2020), when the initial function is a Gold function. In ... -
Partially APN functions with APN-like polynomial representations
(Journal article; Peer reviewed, 2020)In this paper we investigate several families of monomial functions with APN-like exponents that are not APN, but are partially 0-APN for infinitely many extensions of the binary field F2. We also investigate the differential ... -
Proposing an MILP-based method for the experimental verification of difference-based trails: application to SPECK, SIMECK
(Journal article; Peer reviewed, 2021)Searching for the right pairs of inputs in difference-based distinguishers is an important task for the experimental verification of the distinguishers in symmetric-key ciphers. In this paper, we develop an MILP-based ...
