Digital steganography has a long history, starting to be developed in the 90s until now. The
main aspects of early steganography are security, imperceptibility, and payload. Security is …

In the contemporary landscape, where a huge amount of data plays a vital role, the
importance of strong and robust cybersecurity measures has become increasingly …

In the research of multi-image encryption (MIE), the image type and size are important
factors that limit the algorithm design. For this reason, the multi-image (MI) hybrid encryption …

A multiple-image encryption algorithm based on single-channel scrambling, diffusion and
chaotic system is presented in this paper. The initial values of the chaotic system are …

A two-dimensional cross-mode hyperchaotic map based on logistic and sine maps (2D-
CLSS) is presented. The hyperchaotic map consists of a logistic map and two sine maps …

In this paper, a novel triple-image encryption and hiding algorithm is proposed by combining
a 2D chaotic system, compressive sensing (CS) and the 3D discrete cosine transform (DCT) …

Visually meaningful image encryption may keep the data security and appearance security
of the digital images. However, there are still security and efficiency shortcomings existing in …

A new meaningful image encryption algorithm based on compressive sensing (CS) and
integer wavelet transformation (IWT) is proposed in this study. First of all, the initial values of …

Some existing image encryption schemes based on chaotic systems have various security
defects, such as non-uniform distribution of the chaotic system's phase trajectory, narrow …

A new improved three-dimensional continuous chaotic system (ImproBsys) is designed in
this paper. It can achieve from an ordinary chaotic state to a hyperchaotic state, that is …
