Objectives: To design a fast and efficient color image encryption technique using 2D Duffing, Henon and Tinkerbell maps. Methods: The presented work employs the confusion-diffusion-confusion structure for encryption. Pixellevel scrambling is undertaken in the first phase of confusion, and the scrambled image is diffused using the Exclusive-OR operation. Finally, bitlevel permutation is used for improved security. This work makes use of the 44 samples from the USC-SIPI image database. Findings:

Novelty: This work employs a confusion-diffusion-confusion framework which increases algorithmic security by 47.8%. Further, a novel key generation scheme is designed to generate dynamic and input image-sensitive keys. Applications/Improvements: The simple Exclusive-OR operation-based diffusion that is devised significantly minimizes encryption time, thereby making it ideal for real-time applications.
