Image Encryption Scheme Based on Novel Hyperchaotic System
Yan Ping Sun · 2011
Proposed a new hyperchaotic system,analyzed the new system,the phase diagram of the chaptic attractor,and the nature of the equilibrium point,Lyapunov exponent,nonlinear dynamics properties and so on,proposed a novel image encryption scheme based on a four dimensional hyperchaotic system.The experimental results and security analysis show that the new scheme has stronger resistance for the exhaustion attack,count attack and known-plaintext attack,and it is of high security.
