This paper is devoted to the analysis of the impact of chaos-based techniques on block
encryption ciphers. We present several chaos based ciphers. Using the well-known …

This paper proposes a new adaptive least-significant-bit (LSB) steganographic method
using pixel-value differencing (PVD) that provides a larger embedding capacity and …

The processing of simple least-significant-bit (LSB) substitution embeds the secret image in
the least significant bits of the pixels in the host image. This processing may degrade the …

We discuss the relationship between cryptography and chaos theory, and similarities of their
crucial concepts such as mixing property and sensitivity to changes in initial conditions and …

In this paper, some of the mathematical properties relevant to the use of chaotic dynamical
systems in cryptography are identified and reviewed. We evaluate these properties for some …

In this paper, a capacity promoting technique is proposed for embedding data in an image
using pixel-value differencing (PVD). The PVD scheme embeds data by changing the …

Difference expansion and histogram shifting methods are two popular hiding strategies that
have been widely used in many researches. For example, Hong and Chen developed a …

In this paper, we shall propose a novel image-hiding scheme. Our new scheme classifies
the host image pixels into two groups of pixels according to the pixel values. For each group …

In this paper, a novel steganographic method is proposed employing an immune
programming strategy to find a near-optimal solution for the pair-wise least-significant-bit …

Taking the Lorenz chaotic system as an example, FPGA (Field Programmable Gate Array)
technology is applied to obtain chaotic sequence in this paper, the Xilinx system generator …
