摘　　要：在Cat-Logistic模型的基础上提出一种安全网络编码方法。构造Cat-Logistic映射模型,根据该模型生成三级密钥信息,对密钥信息进行迭代处理,通过取余的方式将密文信息传送给随机数生成器,产生种子秘钥增强编码的安全性。加密数据经过混沌系统生成加密信息,运用信宿列表译码算法将接收到的数据信息整合成信源密文,利用混沌序列解密得到原始信息。理论分析与仿真实验结果表明,该方法对多种窃听和污染攻击具有较强的抵抗能力。This paper presents a secure network coding method which is based on Cat-Logistic model. A Cat-Logistic mapping model is given, three secret key information is generated by the model, the key information is processed iteratively,this paper takes the remainder of the encrypted information and transmits it to a random number generator which generates secret key of seeds to enhance security code. Encrypted data generates encrypted information through the chaotic system. List decoding algorithm is used to integrate the receiving data in order to obtain the encrypted information of sources. The original information is obtained by chaotic sequence decryption process. Theoretical analysis and simulation experimental result shows that this method has strong ability to resist on a variety of eavesdropping and pollution attack.
