基于 Logistic 混沌映射的图像加密系统及 FPGA 实现
Image Encryption System Based on Logistic Chaotic Map and the Implementation Using FPGA
摘要
Abstract
Chaotic sequence is used in spread spectrum communication system, and has the advanta-ges of secure and diverse in form.After analyzing the definition of Logistic chaotic system, sensitivity, Lya-punov exponent and correlation properties, logistic chaotic sequence is used for image encryption, and the feasibility of the algorithm is verified by simulation and FPGA hardware implementation.The simulation re-sults show that the encryption system has good resistance to attack and it can fully recover the original image with correct keys.Besides, the FPGA hardware implementation system has characteristics of small volume, low power consumption and good image security.关键词
