高性能正弦超混沌构造及红外图像安全保护
High performance hyper-chaotic system constructed with sine function and its application in infrared image security protection
摘要
Abstract
Aiming at infrared image security protection in early warning detection system, an image encryption and steganography method based on high performance hyperchaotic system is proposed.Firstly,a high performance 2D hyper-chaotic system is constructed by combination sine function with close-loop modulation technique. Secondly, the weak structure random sequence is generated by the proposed hyperchaotic system with larger lyapunov index,and it is applied to control the pixel diffusion operation with feedback structure to realize image encryption,which is combined exclusive-or operation,include-or operation,with adding operations in finite field.In the end,the pixel location information is embedded into the pixel value of cipher image, and cipher image is camouflaged as texture image with some significance. Experi-mental results show that the proposed image encryption method has high security,and the steganography method of cipher image is simple and effective.关键词
