Focusing on maintaining the privacy of images stored in the cloud, this research introduces an innovative image encryption technique that is based on a modified Skew Tent chaotic map. The suggested modification to the chaotic map includes combining the Skew Tent map with both the sine trigonometric...

Extending the probabilistic approach, which is generally employed in asymmetric encryption, this paper proposes a new chaos-based probabilistic symmetric encryption scheme with customizable block-size suitable for image encryption. It employs a Random Bits Insertion phase followed by four rounds of two-st...
The complex structure of the traditional block ciphers makes them unsuitable for real-time encryption of digital images and videos. Real-time applications require fast algorithms with acceptable security strengths. This paper presents a simple chaosbased image encryption scheme using cryptographic ...
The subsequent phase of diffusion is based on pixel distortion, i.e., adding an additional layer of protection to the initial phase of confusion and thus improving overall security. In general, two principal components are necessary to design a secure scheme; the image encryption symmetric key ...

Secondly, by applying MCML chaos, we design a new key binding and distribution rule, the improved diffusion scheme to encrypt image. Furthermore, the novel bit Z-scan scrambling method also be used to enhance the security of the encryption scheme. Finally, a large number of experimental ...
In the permutation-only image encryption algorithm, the multi- media information is scrambled using a permutation mapping matrix generated by a PRBG. In previous studies [20–23], a chaos-based visual encryption mechanism, 2D chaos-based visual encryption scheme, C# based chaotic single map ...
