An Image Encryption Algorithm Based on Five-dimension Chaotic System
Guangyi Wang · Journal of Hangzhou Dianzi University · 2011
A new image encryption algorithm based on five-dimension chaotic system is proposed in this paper.First,five chaotic sequences are generated by the modified five-dimension Lu system.One of those five chaotic sequences is used to scramble the image,and then divide the scrambled image into four parts,the pixels of every part will be changed using the other four chaotic sequences.At last,the encryption effect and security are analyzed.Simulation experimental results show that this algorithm is of high security and good encryption effect because the key space of this algorithm is large and the cipher image pixels value distributes uniformly.
