摘　　要：针对原有加密方法解密后信息完整度较低的问题,提出基于动态密钥选择的网络隐私信息双重加密方法。设计动态密钥协议工作过程,利用网络通信中常见攻击类型构建网络隐私信息数据库。采用动态密钥选择技术结合混沌加密算法,设计网络隐私信息双重加密算法。选取DSP芯片,构建网络隐私信息双重加密平台,为加密算法提供硬件基础,完成网络隐私信息双重加密。仿真实验结果表明,此加密方法解密后信息完整度更高,可靠性更好。In order to solve the problem of low information integrity after the original encryption method is decrypted,a dual encryption method of network privacy information based on dynamic key selection is proposed.According to the working process of dynamic key protocol,the network privacy information database is constructed by using common attack types in network communication. The double encryption algorithm of network privacy information is designed by using dynamic key selection technology and chaos encryption algorithm. The DSP chip is selected to build the double encryption platform of network privacy information,which provides the hardware foundation for encryption algorithm and realizes the double encryption of network privacy information. Simulation results show that the encryption method has higher information integrity and reliability after decryption.
