摘要
Abstract
Traditional encryption systems based on chaos generally use fixed parameters,and the analysis and deciphering of the system orbit makes the algorithm less secure.To solve such problems,a new image encryption algorithm of variable parameter logistic system is proposed.A set of changing logistic system parameters were generated by dynamic transformation,and then a set of random sequences were generated by this system,which were used for position scrambling and Pixel transformation.Two-way diffusion was used to get the encrypted image.The algorithm was implemented through simulation and performance testing.The analysis shows that the algorithm can effectively deal with a variety of attack methods,and it is highly sensitive to keys,which shows that the algorithm has high security and relia-bility.关键词
