摘要: 针对视频数据实时性高，数据量大等特点，提出了一种基于细胞神经网络的视频加密新算法。该算法以五维CNN 作为密钥源，根据明文视频帧的尺寸和明文视频帧本身来选择加密密钥，依据扩散思想，对视频进行加密处理。该算法加/解密速度快，可对任何格式的视频数据实现保密通信，具备通用性，且密钥敏感性和明文敏感性强，密钥空间大，可有效抵抗穷举攻击、统计分析攻击、已知明文攻击、选择明文攻击和密文攻击，安全性更高，具有一定的实用价值。

Abstract: Aiming at video data high real-time performance,the characteristics of large amount of data, proposed a new video encryption algorithm based on cellular neural network.In the algorithm,five dimen-sional CNN hyperchaotic system have been used as key source,according to the plaintext video frame size and the plaintext video frame itself,selected the encryption key,based on diffusion theory,encrypted vid-eo.The encryption and decryption speed of the algorithm is fast,any format video data can achieve secure communications,has universality;the key sensitivity and plaintext sensitivity are strong,the key space is large.Can effectively resist brute attack,statistical attack,known plaintext attack,chosen plaintext at-tack and cipher text attack,has higher security and a certain practical value.
