Image encryption is an essential method for ensuring confidentiality during transmission on
open channels. Digital images have a high correlation with large redundant data, requiring …

Image encryption protects visual information by transforming images into an
incomprehensible form. Chaotic systems are used to design image ciphers due to properties …

This paper introduces new simple and effective improved one-dimension (1D) Logistic map
and Sine map made by the output sequences of two same existing 1D chaotic maps. The …

The use of chaotic maps for cryptography is advantageous due to their desirable
characteristics, including complexity, unpredictability, sensitivity to initial values and control …

Digital chaotic maps are becoming increasingly popular in the area of cryptography due to
commonalities but have drawbacks which adversely effect security strength. Thus …

Chaotic maps that can provide highly secure key sequences and ease of structure
implementation are predominant requirements in image encryption systems. One …

Chaotic systems are broadly adopted to generate pseudo-random numbers used in
encryption schemes. However, when implemented on a finite precision computer, chaotic …

For recent decades, the increasing volume of multimedia data has been witnessed, and the
data is required technical methods to assure the security for storage and transmission …

Chaos maps are widely used in image encryption systems due to their intrinsic advantages
such as extreme sensitivity to initial values., ergodicity and pseudo-randomness. 1D Logistic …

In this study, an enhanced quadratic map (EQM) is proposed and has been applied in a new
colour image encryption scheme. The performance evaluations show that the EQM has …
