摘要
利用混沌系统敏感依赖于初始条件的特性,迭代Lorenz三维混沌系统生成的三组伪随机序列,设计算法加密真彩色图像的红绿蓝三个分量。采用多个衡量指标的测试结果表明,该算法具有较大的密钥空间,加密效果令人满意。
Use the characteristics of chaotic system sensitive depending on the initial conditions of, iterative the three dimensional Lorenz chaotic system to generate three groups of pseudo random sequence, design algorithm to encrypt true color image of red, green and blue components. Use each indicator test results show that this algorithm has large key space, and can get the ideal effect of encryption.
