【Abstract】 The chaotic sequence is pseudo-random,and it can be used to compose encryption system.This paper gives a multistage chaotic encryption algorithm.Because chaos is extremely sensitive to error,we use the neural network which can spread error to improve the algorithm.The simulation reveals that the algorithm is more security and easier to implement.更多还原
