Rui Jing · Journal of Shanghai Second Polytechnic University · 2011
As the development of information technology,people need more security on image safety.Image encryption is an effective technology for the digital information protection.This thesis introduces a new image encryption algorithm based on Black-hole numbers and Logistic chaos sequence.By research the Black-hole number,it can have a chaos sequence and the chaos sequence which will be sent into Logistic algorithm as the initial parameters.Then the algorithm can generate chaotic key stream for image encryption.The result shows that the system runs fastly and security of the image encryption is very high.
