Summary form only given. Along with the rapid development and wide application of Internet technique, the research about communication security becomes a very important topic in theory and the practice. For the explicitness and large information content of images, much attention has been paid to the security of image storing and transmission in communication. As one of the key technique of digital...
The Lorenz chaotic system is applied to the digital image encryption based on the thought of higher secrecy of high-dimension chaotic system in this paper. Firstly, the pretreatment to the real value chaotic sequences produced by the system is carried out. Secondly, the index matrix of pixel permutation is structured by this real value chaotic sequence. Finally, the spatial-domain encryption of digital...
