Chaotic System Based Modified Hill Cipher Algorithm for Image Encryption Using HLS

Lately, information has risen as an imperative asset, and henceforth information safety is of essential concern. A novel and secure image cryptographic system based on the hill cipher algorithm and incorporating a Nose Hoover Chaotic generator has been presented. In the proposed system, the transmission unit mixes an input image with chaotic noise produced by a Chaotic generator and then a bitwise XOR operation is performed to complete the encryption with higher degree of robustness which has been proved by using various measures like entropy and correlation. Moreover, a comparison has been made in the paper. The proposed algorithm includes a key generation system on board which provides an enhanced robustness as well as better computation speed. This makes the algorithm unique and novel since the traditional Hill Cipher has been modified to accommodate pixel values. In addition to the proposed algorithm, we have offered a way to implement the design on a SoC using Xilinx Vivado Design suite.
