An Implementation of Hyperchaotic Encryption Based Steganography with XOR Operation in Wireless Transmission

Abstract

Steganography is the art of employing digital graphics to conceal a message such that only the sender and the intended recipient can find out about its existence. The hyperchaotic encryption algorithm, which minimizes the computational complexity of the chaotic encryption technique and the foundation of the proposed system in this project to improve bit insertion. The suggested bitwise operation based on encryption changes the encryption phases from permutation to XOR and XOR to bit insertion. The next step is to create a four-dimensional hyperchaotic system that uses the chaotic system’s discrete time signal as the key generator and its necessary mapping. This result demonstrates how steganography may be used to increase security by monitoring the speed and quality of data sources. Additionally, an acceptable PSNR is obtained, which is higher than MSE (Mean-Square Error) and improves the quality of the steganosource.
