Abstract: Multimedia security is continuously trending in the digital era. Because of the heterogeneous form of multimedia data and requirement of secure access, the challenges are also increasing. In this paper, an image cryptosystem is proposed. The methodology is based on image decomposition and permutation-diffusion architecture. The novelty of the algorithm is the generation of different encryption keys . These keys are self-adapted in permutationdiffusion rounds. The cryptosystem is designed and implemented by software means.
