摘　　要：文章提出一种非对称加密与细胞神经网络加密相结合的警务图像加密算法,采用细胞神经网络混沌系统产生的混沌随机序列对警务图像进行加密,并采用非对称加密算法对输入混沌系统的密钥初值进行加密保护。实验结果表明,文章算法设计简单、密钥空间大且敏感性强,对警务图像的加密保护有较高的安全性和鲁棒性,具有较好的应用前景。This paper proposes a police image encryption algorithm based on the combination of asymmetric encryption and the cellular neural networks encryption. It uses the chaotic random sequence generated by the chaotic system of cellular neural networks to encrypt the police image, and uses the asymmetric encryption algorithm to protect the input key value of the chaotic system. The experimental results show that this algorithm is simple,and have large key space with strong sensitivity. It has high security and high robustness for the encryption and protection of police images, and has a good prospect of utilization.
