Digital encryption method based on Lorenz continuous chaotic system
With the development of networking and communications technology,data transmission has penetrated into all aspects of life.Such information security has become a problem we have to consider about,Secure transmission of data has become an important indicator of the exchange of information.As the chaotic system has good encryption features,so this paper describes a method of digital encryption based on Lorenz continuous chaotic system,combined with chaotic dynamics,continuous sequence of numbers generated by the Lorenz chaotic system.Discrete the continuous data through the Euler method.Image encryption as an example,verify the Lorenz chaotic system digital encryption features.MATLAB simulation shows that the method can achieve image encryption and decryption,ensure the security of data transmission.
