Abstract: We propose a non-cascaded and crosstalk-free multi-image ... patterns as encryption keys at the pupil, multiple samplings can be achieved and ultimately the holographic cyphertext can be ...

This code provides various encryption and scrambling techniques for digital images, including the Logistic map, Henon map, AES encryption, Arnold transform, and Hyper Chaotic Chen system.

A Python GUI tool for learning classical encryption & decryption. Supports Caesar, Playfair, Rail Fence, ROT13, Substitution & Vigenère ciphers. Includes file ...

In this paper is studied middle square method and then a logistic chaotic map is introduced with its specific features and its improved weaknesses via using these characteristics. Finally the NIST ...

In this work, a data encryption technique using a three-dimensional chaotic map and highly nonlinear substitution boxes for the encryption of secret images, followed by a data hiding scheme based on ...
