technique to improve the performance of encryption algorithms. Compared to other chaotic …

In view of the problem that dissipative chaos has attractors and is easy to be attacked by
reconstruction, which leads to the security defects of encryption algorithm based on …

Due to the unpredictability and complexity properties, chaotic maps are widely applied in
security, communication, and system control. Existing one-dimensional (1D) chaotic maps …

In this paper, a digital image encryption algorithm is proposed based on the generalized
model of the chaos game. The chaos game is a well-known fractal, which acts as a pseudo …

Image encryption schemes can be vulnerable to a variety of cryptanalysis attacks. The use of
key-dependent dynamic S-boxes has been shown to improve security. Threats of chosen …

Objective In order to avoid the unauthorized access to private images and make a secure
communication, an asymmetric image encryption algorithm based on SHA-3 and …

This paper presents a novel lossless image encryption algorithm based on edge detection
and generalized chaotic maps for key generation. Generalized chaotic maps, including the …

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 …

Symmetric encryption has been considered as one of the essential means of ensuring
security of end to end communication. The robustness and strength of modern day block …
