Block ciphers are widely used in modern cryptography. Substitution boxes (S-boxes) are
main elements of these types of ciphers. In this paper we propose a new method to create S …

Finding cryptographic primitives satisfying certain properties is a difficult problem. In this
domain, besides the algebraic constructions, researchers often use heuristics. There exists a …

In this paper, we presented a low-power, less area architecture of S-Box used in advanced
encryption standard (AES) using programmable cellular automata (PCA). The proposed …

In this study we propose a new design method for fast S-box construction. Its security is
dependent upon the length of pseudorandom numbers generated by two communication …

With the emergence of the Internet of Things and lightweight cryptography, one can observe
a gradual shift of interest in the design of block ciphers. Naturally, security is still of …

We propose a new set of benchmark problems that come from the field of cryptography.
These problems are often easy to define, they are relevant in practice, and some of them …

Quantum Cellular Automata (QCA) represents an emerging technology at the nano
technology level. Nowadays, many applications of QCA technology are introduced and …

Arama uzayının büyüklüğünden dolayı sezgisel ve evrimsel arama algoritmaları, güçlü
kriptografik özelliklere sahip S-kutularını elde etmek için literatürde genellikle sekiz ve daha …

In the paper we use recently proposed cellular automata (CA)-based methodology [9] to
design 6x4 S-boxes functionally equivalent to S-boxes used in current cryptographic …
