Cryptography often involves substituting (and converting) the secret information into dummy
data so that it could reach the desired destination without leakage. Within symmetric key …

In EUROCRYPT 2018, Cid et al. introduced a new concept on the cryptographic property of
S-boxes: boomerang connectivity table (BCT for short) for evaluating the subtleties of …

This paper introduces a new variant of the metaheuristic algorithm based on the naked mole
rat (NMR) algorithm, called the Q-learning naked mole rat algorithm (QL-NMR), for …

This paper introduces a new variant of a metaheuristic algorithm based on Agent Heroes
and Cowards Algorithm (AHC), called Adaptive Agent Heroes and Cowards Algorithm …

Often the S-boxes are the only nonlinear components in a block cipher and as such play an
important role in ensuring its resistance to cryptanalysis. Cryptographic properties and …

This paper introduces a new variant of a recent metaheuristic algorithm based on the Social
Network Search algorithm (SNS), which is called the Roulette Wheel Social Network Search …

S-boxes play an important role in ensuring the resistance of block ciphers against
cryptanalysis as often they are their only nonlinear components. The cryptographic …

The existence of almost perfect nonlinear (APN) permutations operating on an even number
of variables was a long-standing open problem, until an example with six variables was …

Motivated by recent works on the butterfly structure, particularly by its generalization
introduced by Canteaut et al.(IEEE Trans Inf Theory 63 (11): 7575–7591, 2017), we first …

The security of the block cipher largely depends upon the cryptographic strength of the S-
Boxes resistance to the existing cryptanalytic attacks. The nonlinearity and differential …
