A Novel Image Encryption using Improved Chaotic Maps and Multiple Encryption Tables

This paper proposes a new symmetric cryptographic system using chaotic systems. The basic idea is that random strand generated from functions. developed merged with the obtained original image. researcher used tables called multiple encryption in composition of these strands. These are produced according to specific pattern. combination algorithm randomly selects table set and performs operation. will be replaced another under certain conditions. diversity their dynamic selection integration operation increase resistance attacks threats proposed system's efficiency. To prove efficiency, results have been evaluated by various tests such as entropy, correlation coefficient, pixel change rate. Our show cost-efficient, practical, resistant, yet further research required make final statement about its competence.
