摘要: Content protection is considered as an important issue in today’s world. Therefore, encryption of such contents a challenging task for researchers. They are focusing on valuable data image, video, and audio against different attacks from eavesdroppers. In this paper, we proposed enhanced version Fawad et al.’s scheme to fulfill essential needs secure image algorithm. The cryptosystem resistant many like brute force, differential statistical. To quantify the quality scheme, instead visual inspection, analyzed through various tests, correlation coefficient, information entropy, Number Pixel Change Rate (NPCR) Unified Average Intensity (UACI). Simulation results presented shows good diffusion characteristics when compared other traditional schemes.
