This paper is to design substitution boxes (S-Boxes) using innovative I-Ching operators
(ICOs) that have evolved from ancient Chinese I-Ching philosophy. These three operators …

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 …

One-dimensional (1-D) chaotic maps have been considered as prominent pseudo-random
source for the design of different cryptographic primitives. They have the advantages of …

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 …

Substitution boxes (S-Boxes) are essential elements of modern block ciphers, serving as
non-linear characteristics that enhance the resistance of these ciphers against cryptanalysis …

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 …

Logic encryption has recently gained interest as a countermeasure against IP piracy and
reverse engineering attacks. A secret key is used to lock/encrypt an IC such that the IC will …

When studying the DPA resistance of S-boxes, the research community is divided in their
opinions on what properties should be considered. So far, there exist only a few properties …

Cryptosystems are commonly deployed to secure data transmission over an insecure line of
communication. To provide confusion in the data over insecure networks, substitution boxes …

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 …
