Nowadays, the use of the Internet of Things has reached a commanding height in a new
round of economic and technological upsurge. Its data transmission security has attracted …

This article presents theLIGHTER-R'tool that aims at implementing a given 4-bit SBox using
reversible logic libraries. An SBox is a basic building block in the symmetric key …

We analyze five newly emerged cryptographic characteristics and a new notion of algebraic
immunity proposed by us of 16 best affine equivalence classes of 4× 4 S-boxes, as well as …

An optimized implementation of S-boxes has a significant impact on the performance of
cryptographic primitives. SAT-based methods can find optimal implementations for …

For many years, chaotic maps have been widely used in the design of various algorithms in
cryptographic systems. In this paper, a new model (compound chaotic system) of quantum …

In this paper, we propose several reduction rules to optimize the given implementation of a
binary matrix over F 2. Moreover, we design a top-layer framework which can make use of …

This paper reviews the state of the art of symmetric key block cipher designs and their
essential security role in several applications like IoT, low-power devices like motes, etc …

This paper presents four low-cost substitution boxes (S-boxes), including two 4-bit S-boxes
called S< sub> 1 and S< sub> 2 and two 8-bit S-boxes called SB< sub> 1 and SB< sub> 2 …

The substitution box (S-box) is an important nonlinear component in most symmetric
cryptosystems and thus should have good properties. Its difference distribution table (DDT) …

Substitution boxes (S-boxes) are essential components of many cryptographic primitives.
The Dijkstra algorithm, SAT solvers, and heuristic methods have been used to find bitsliced …
