Four chaotic maps are used herein as case study to design an embedded cryptosystem
based on a pseudo-random number generator (PRNG). The randomness of the sequences …

Chaotic systems are widely used in image encryption due to their sensitivity to initial values,
ergodicity, and other properties; many image encryption algorithms based on chaotic …

This paper proposes a lightweight image encryption scheme that is based on 3 stages. The
first stage incorporates the use of the Rössler attractor for the Rössler system, the second …

The expansion of worldwide networking has created new possibilities for management,
development, and presentation in the form of digital data. The uncomplicated accessibility to …

The need for image encryption schemes that are of low computation complexity is ever
increasing. Meanwhile, the use of chaotic functions and mathematical sequences to …

Protection of data transmitted over the network from illegal access is one of the major
challenges being posed by exponential growth of data in online digital communication …

In this article, we present an encryption technique that can encrypt any digital data. The
proposed scheme basically depends on a substitution-permutation network. Two separate …

Efficient multiple pseudo-random number sequences (PRNS) and substitution boxes (S-
boxes) are one of the most significant building blocks, which are jointly adopted normally for …
