A Fast and Secure Image Cryptosystem Based on New Row_Column Index Manipulator and Split_Join Algorithm

Securing image data during communication influences employing encryption, authentication, integrity reviews, and other protection measures to stop unauthorized access and tampering. Encryption methods contain confusion and diffusion to preserve the security of image data by intricately changing the relationship among original and encrypted data and distributing pixel effects across the entirety of the encrypted image. Therefore, by prioritizing security while also addressing computational resources, we have designed a system for encrypting images. This includes using the row and column index manipulator algorithm for initial scrambling and integrating the split and join algorithm for an added coating of confusion. To accomplish diffusion goals, a pseudo-random sequence generator is created, utilizing the logistic map for both diffusion and confusion processes. The results and estimation of the proposed technique highlight its strong randomness and resilience against entropy-based, statistical, differential, and brute-force attacks.
