Abstract The Internet of Things is a resource-constrained device that demands lightweight
cryptographic solutions to achieve high performance and optimal security. In lightweight …

Substitution Boxes (S-Boxes) play an important role in many modern-day cryptographic
algorithms, more commonly known as ciphers. Without carefully chosen S-Boxes, such …

Substitution boxes are the main nonlinear component of block ciphers. The security of these
ciphers against linear, differential, or side-channel attacks is dependent on the design of …

This work investigates the development of an improved cost function specifically designed
for the rapid generation of highly nonlinear substitution or S-boxes, a key component in …

In this paper, we consider the multi-bit Differential Power Analysis (DPA) in the Hamming
weight model. In this regard, we revisit the definition of Transparency Order (TO TO) from the …

Side-channel attacks represent a powerful category of attacks against cryptographic
devices. Still, side-channel analysis for lightweight ciphers is much less investigated than for …

The property of nonlinearity has high importance for the design of strong substitution boxes.
Therefore, the development of new techniques to produce substitution boxes with high …

The boomerang uniformity measures the resistance of block ciphers to boomerang attacks
and has become an essential criterion of the substitution box (S-box). However, the S-box es …

In this paper, we explore a heuristic method called the bee waggle dance to construct
cryptographically strong S-boxes. The S-boxes exhibit good cryptographic properties such …

We revisit the definition of transparency order (TO) and that of modified transparency order
(MTO) as well, which were proposed to measure the resistance of substitution boxes (S …
