摘要
En 中文
In order to combine chaos with image encryption better, a composite hyperchaotic system is constructed by introducing a feedback controller, and then a new image encryption method based on hyperchaos and bit plane is proposed. Two images are scrambled into one through the method of bit plane decomposition. The image is divided into high-bit and low-bit planes, which are put into two matrices respectively, and then an auxiliary matrix is constructed with hyperchaotic sequence for encryption. After a round of scrambling diffusion algorithm, a picture is synthesized by bit plane, and then a round of modular diffusion encryption is carried out. The experimental results show that the proposed algorithm has high sensitivity and can resist several common attacks. It is proved that the combination of chaotic system and image encryption technology can effectively improve the security of this system.
