An improved bit plane image encryption technique using RC4 and quantum chaotic demeanour

To compete with the rising apprehension of data/image security, corporations are endorsing cryptography for protection. A high-quality image encryption scheme must ensure high Entropy, high key sensitivity, ability to resist known and chosen-plaintext attack, large keyspace, high randomness, and resistance towards differential attack. To accomplish this need, an improved bit plane image encryption scheme using RC4 and Quantum Chaotic behavior is proposed. In the projected mechanism, to ensure less bandwidth usage and efficient transmission of data over the network, YCbCr format is used. The keys are generated using the s- logistic map due to its high randomness, non-periodic behavior, and large keyspace to resist brute-force attacks. This contemporary encryption process includes confusion and diffusion stages. For the confusion stage, the Channel transformation process is employed, which helps in attaining randomness. A multilevel diffusion stage is implemented using CBC (Cipher Block chaining block), Zigzag permutation, and Inter bit plane permutation process. Additionally, the technique's randomness and complexity are strengthened by utilizing RC4 to generate S-box for byte substitution. The projected framework is implemented in MATLAB and assessed using various performance metrics like mean square error (MSE), Peak Signal to noise ratio (PSNR), Entropy, and others referenced in writing. Result analysis illustrates that the proposed model reveals its capacity to conceal the confidentiality of information of the transmitted image and is more efficient than its classical counterpart. Its security is verified by the statistical, key-space, and key analysis.
