Chaotic Image Encryptio Nsystem Based On Genetic Algorithm

Information security always revolves around people's life.With the rapid development of multimedia and cloud computing technology in recent years,how to protect data privacy,especially image information,has become the most concerned,and urgent problem to be solved.Encrypting the transmitted image is an important technology to prevent data privacy from leaking.The study found that Chaotic characteristic has its unique pseudo-random orbits and topological transitivity,and it owes the sensitive dependence on primeval conditions and parameters.These characteristics can play an important role in image encryption application technology.Compared to the traditional encryption methods,an image encryption system combined with chaos theory can make image encryption better and has higher security.This analysis of the chaos theory,try to applychaotic theories to the image encryption,the corresponding image encryption program based on chaotic theories.The initial encryption algorithm for image is proposed in this paper,andthe research work can be stated as follows:(1)Firstly,the scrambling algorithm and the diffusion algorithm commonly used in image encryption algorithms are compared and analyzed,compare and analyze the related algorithms using common analysis indicators.(2)In order to improve the image encryption efficiency of different complexity levels,this paper proposes a chaotic digital image encryption scheme based on genetic algorithm.Through the feature of genetic algorithm optimization to optimize some parameters in the encryption process.The experimental results show that the encryption scheme combined with genetic algorithm can not only solve the ubiquitous image encryption efficiency problem,but also improve the security in the encryption process.(3)An image encryption algorithm that enhances key security is proposed.Compared with the traditional digital image encryption algorithm,the algorithm does not add additional technical operations,and can guarantee the efficiency of the original algorithm and reasonable encryption/decryption time.
