In this paper, a new image encryption algorithm and its VLSI architecture are proposed. Based on a defined bit recirculation function and a binary sequence generated from a chaotic system, the gray level of each pixel in the image is transformed. The features of the algorithm are as follows: 1) low computational complexity, 2) high security, and 3) no distortion. In order to implement the system, its VLSI architecture with low hardware complexity, high computing speed, and high feasibility for VLSI implementation is also designed. Finally, two encrypted images are simulated and the fractal dimensions of the original and encrypted images are computed to demonstrate the effectiveness of the proposed algorithm
