Abstract

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.

一种新的图像加密算法及其VLSI结构

本文提出了一种新的图像加密算法及其VLSI结构。基于定义的位循环函数和混沌系统生成的二值序列，对图像中每个像素的灰度进行变换。该算法具有以下特点:1)计算复杂度低;2)安全性高;3)不失真。为了实现该系统，设计了硬件复杂度低、计算速度快、VLSI实现可行性高的VLSI架构。最后，对两幅加密后的图像进行了仿真，计算了原始图像和加密后图像的分形维数，验证了算法的有效性。
