Design Simulation and Analysis for Securing Medical Images Using Hybrid Algorithm

Abstract

This research is focused to use a hybrid encryption method. This hybrid system uses both the AES and RSA algorithms. To compare the efficacy of the four proposed algorithms, additional testing was done on both colour and grayscale photographs with varied text sizes. Our methods produced higher PSNR and MSE values than the reference data. When comparing 2D-DWT-3L with hybrid (AES and RSA) to other approaches, it was found that while text encryption increases the security of the text, it decreases the invisibility of the cover picture. To put it another way, text encryption exacerbates the distortion of the cover image, making it more visible to those who shouldn't. As a result, when compared to the reference methodology used in this study, our proposed methods were more effective in concealing hidden information.
