A Synergistic Approach for Enhancing Image Encryption by Implementing Double Random Permutation and Memristive Chaos

The growing academic interest in the secure transmission of optical digital images has led to a surge in awareness of information security within photonics circumstances. This work presents a hybrid encryption strategy based on the memristor hyperchaotic system and a double random transform for pictures in the frequency and spatial domains. This study presents a robust and secure picture encryption technique that combines compressed sensing, double random phase encoding (DRPE), and Lorenz map. We also make doublerandom-phase masks using Lorenz maps, which enhance the unpredictability and key sensitivity, thereby improving the security of the encryption method. Experimental studies utilize a range of performance metrics, such as the PSNR, NPCR, MSE, and SSIM, to show the value of the suggested approach.
