【Abstract】 Chaos is a kind of behavior controlled by nonlinear dynamics law.This paper proposes a kind of digital image encryption algorithm based on Henon mapping,this algorithm uses Henon mapping to generate stochastic sequence,then rearranges this sequence according to certain order,conducts exclusive or operation with initial image after sequencing transformation,and then obtains encrypted image.Theoretical analysis and simulation experiment show that this scheme has good statistical property and encryption effect and is a kind of effective image encryption algorithm.更多还原
