摘要
Abstract
This paper proposes a new composite structure for generating 1D chaotic system.Two new 1D chaotic systems are designed by using this structure.Through plotting Lyapunov exponent diagram and bifurcation diagram we studied the performance of two new chaotic systems,study results showed that the new 1D chaotic system generated by this structure had the advantages of large and continuous chaotic range,uniform chaotic sequence distribution,high system Lyapunov exponent and more controllable parameters,etc.In order to further improve the uniformity of chaotic sequence distribution,we designed a transformation process.After the transformation the chaotic sequence satisfied the uniform distribution.At last,in order to demonstrate its applications in information security,we designed a simple image encryption and decryption algorithm.The new systems were simulated and tested their performances on Matlab,results showed that after the transformation the chaotic sequence had higher encryption characteristic.关键词
