Abstract: In this study, declared a new fangled methodology for image encryption using one of the cryptographic modes. The need for protection rises phenomenally with greater than before custom of internet and online communication. It is challenging and crucial to safeguard the information be it any multimedia file online and to check illegal entrée’. Naturally images play a huge role in doing so in so called cryptographic and steganographic techniques. The former is very primeval but interestingly is still in use and lends a helping hand to realize secret sharing. Of the various fruits of cryptographic techniques, image encryption is awe-inspiring having multiple proficiencies possessing countless platforms to explore. This paper paints yet another advantageous model to image encryption where the image undergoes exceptional echelon of shuffling, scrambling and encrypting customs with Cipher Block Chaining (CBC) cryptographic mode as the brain. The analytical results demonstrate that this proposal is unsurpassed in the grounds of Correlation, BER, UACI, NPCR, PSNR and MSSIM. The encrypted images and their corresponding histograms are publicized to prove the paper’s purpose creation.
