英文摘要: This project focuses on the strength of random-like property of chaotic signal and its stability, which includes four parts:(1)Propose an algorithm to identify the strength of random-like property of chaos and construct corresponding theory.It can set up and optimize an algorithm which is fit for identifying the strength of random-like property of chaos.(2)Put forward a proposal to analyse the stability of random-like property of chaos and construct corresponding theory.It can build up and optimize an algorithm which is fit for analysing the stability of random-like property of chaos.(3)Campare the random-like property of chaos and its unpredictality, distinguish their difference,and analyse the random-like property and unpredicatability of chaotic signals generated from hareware circuit and chaotic system equations, so as to decide which signal is more suitable for encryption.(4)Carry out application study of random-like property of chaos in digital image encryption and give some security analysis from different aspects. This research achievement can promote the development of chaos theory and its technology, which makes chaos provide reliable function and practical value in formation encryption.
