提出了一种基于混沌幅相频模型（APFM）非线性自适应滤波器的彩色图像加密系统。通过设定9个参数、模拟时间间隔和初始值，使APFM非线性自适应滤波器产生混沌，并利用混沌特性设计了一种彩色图像加密算法。该方案可以对彩色图像（普通图像）进行加密，并将其转换为三分量直方图几乎均匀分布的彩色密码图像。该方案的密钥敏感度可以达到10的-10次方量级，能够获得足够的安全强度来保护彩色图像。此外，我们的加密算法可以成功地通过NIST SP 800- 22 a测试，这证明了所提出的方案是一个安全的密码系统。实验结果和安全性分析表明，该方法具有良好的安全性能。(C)2015 Elsevier B.

In this paper, a novel cryptographic system for color image security using chaotic Amplitude Phase Frequency Model (APFM) nonlinear adaptive filter is proposed. We set nine parameters, simulated time interval, and initial values for APFM nonlinear adaptive filter to generate chaos, and use the chaos property to design a color image encryption algorithm. The proposed scheme could encrypt the color image (plain image), and transform it into the color cipher image whose histograms of three components are almost uniformly distributed. The proposed scheme possesses a key sensitivity can reach the order of 10 to the power of -10 to get sufficient security strength to protect color image. Furthermore, our encryption algorithm can successfully pass the NIST SP 800-22a tests, which verifies the proposed scheme is a safe cryptographic system. The experimental results and security analyses demonstrate that the proposed method has a fine security performance. (C) 2015 Elsevier B.V. All rights reserved.
