Block cipher has been one of the most reliable options by which data security is achieved.
The strength of block cipher against various attacks is purely dependent on its confusion …

Chaotic systems have been used to generate the substitutional box structures. The
existence of endless possibilities for the selection of the initial conditions and control …

Many cryptographic protocol have been realized using similarities between chaos and
cryptology. One of the most successful examples of these protocols has been s-box …

This paper presents a hybrid method for the construction of cryptographically strong bijective
substitution-boxes by utilizing the merits of chaotic map and algebraic groups. The hybrid …

Over the last few decades, different mediums of secure communication use chaos which is
demonstrated by some nonlinear dynamical systems. Chaos shows unpredictable behavior …

This work reports a novel chaos-based affine transformation generation method, which is
based on rotational matrices to design strong key-based S-boxes. Chaotic logistic map's …

Modern cryptographic systems use substitution boxes (S-boxes) throughout the encryption
process to enhance the security of the plaintext. The integrity of the communication process …

Block cipher has been a standout amongst the most reliable option by which data security is
accomplished. Block cipher strength against various attacks relies on substitution boxes. In …

The resistance of S-box-based cryptosystems to linear cryptanalysis is often determined by
the nonlinearity (NL) and the linear approximation probability (LAP) of the underlying S-box …

Gigantic data transfer over networks and internet turned in developing a large number of
encryption techniques. As a consequence, in parallel, it gave birth to new plans of attacks. In …
