基于新的超混沌系统的图像加密方案

提出了一个新的超混沌系统，分析了新系统的混沌吸引子相图、平衡点及其性质、工yapunov指数等非线性动力学特性，并用该超混沌系统对图像进行加密研究。给出了一种新的基于四维超混沌系统的图像加密算法。实验结果及安全性分析表明，该算法具有较强的抵御穷举攻击、统计攻击、已知明文攻击能力，因而具有较高的安全性。

Image Encryption Scheme Based on Novel Hyperchaotic System

Proposed a new hyperchaotic system, analyzed the new system, the phase diagram of the chaptic attractor, and the nature of the ectuilibrium 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.
