A Novel Image Encryption Technique Using Multi-Coupled Map Lattice System with Generalized Symmetric Map and Adaptive Control Parameter

Abstract Image and video data make up a significant portion of the content shared over Internet social media. The use image communication allows more information to be while simultaneously presenting higher risks in terms security. traditional encryption schemes are general purpose; however, encrypt data, application-specific solutions needed. An or frame comprises two-dimensional matrix where pixel intensity values integers range [0,255], leading redundancy problems. Moreover, bulk amount adds another challenge when deploying security primitives. In this paper, novel coupled map lattice system-based cryptosystem has been proposed that uses generalised symmetric maps for generation pseudo-random sequences. generalization user choose source sequence by varying single control parameter. Other adaptive parameters ensure an adequate degree randomness generated system relies on three independent sources generators, which further re-randomized before final process. Comprehensive experimentation performed test against various attack models publicly available datasets. A detailed comparative analysis also conducted with existing state-of-the-art techniques. Results show algorithm provides high entropy, negative correlation, large key space, sensitivity variations, is resistant types attacks, including chosen-text, statistical, differential attacks.
