This paper presents a new way of image encryption scheme, which consists of two
processes; key stream generation process and one-round diffusion process. The first part is …

In this paper, the Chen chaotic system is proposed as a pseudorandom sequence
generator. A new algorithm is created to solve the problem of non-uniform distribution of the …

Robust chaotic systems, due to their inherent properties of mixing, ergodicity, and larger
chaotic parameter space, constitute a perfect candidate for cryptography. This paper reports …

Many cryptographic schemes have been implemented, using the connection between chaos
and cryptography. However, the present study introduces a new algorithm that, as a …

Cryptography deals with designing practical mathematical algorithms having the two
primitive elements of confusion and diffusion. The security of encrypted data is highly …

A generalized method is proposed to compose new orbits from a given chaotic map. The
method provides an approach to examine discrete-time chaotic maps in a “deep-zoom” …

In this study, the authors use a non‐symmetric partition to generate N‐phase pseudorandom
sequences using the logistic maps. The theoretical analysis shows that this N‐phase logistic …

A new byte-shuffling based enhancement of chaotic maps is proposed. The enhancement,
applied to the two-dimensional Henon map, results in another two-dimensional map-Byte …

The newly introduced family of complex chaotic maps has different behavior concerning the
well-known complex chaotic maps. These complex maps have excellent properties such as …

Recently, a novel pseudorandom number generator scheme based on the Chen chaotic
system was proposed. In this study, we analyze the security weaknesses of the proposed …
