A Low Computational Cost RGB Color Image Encryption Scheme Process based on PWLCM Confusion, ℤ/퐧ℤDiffusion and ECBC Avalanche Effect

avalanche effect; chaos enhancement; cipher block chaining enhancement; color image encryption; confusion; diffusion; ring-homomorphic operation

In this work, three sub-processes are serially integrated into just one process in order to construct a robust new image encryption scheme for all types of images, especially color images. This integration architecture aims to create a robust avalanche effect property while respecting the constraints of confusion and diffusion that have been identified by Claude Shannon as properties required of a secure encryption scheme. The performance of the proposed encryption scheme is measured and discussed with several analyses, including computational cost analysis, key space analysis, randomness metrics analysis , histogram analysis, adjacent pixel correlation and entropy analysis. The experimental results demonstrated and validated the performance and robustness of the proposed scheme
