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 …

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 …

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 …

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 …

The biggest challenge for symmetric cryptosystems is to replace their static substitution with
dynamic substitution, because static substitution S-boxes make the symmetric block ciphers …

S-boxes are usual targets of side-channel attacks and it is an open problem to develop
design techniques for S-boxes with improved DPA resistance. One result along that line is …

The known attacks on different cryptosystems lead to a number of criteria that the
implemented cryptographic algorithms (ciphers) must satisfy. The design of cryptographic …
