摘　　要：为缓解相邻密钥组织间协议数据转存安全性过低的问题,设计基于同态映射的密钥协商协议加密系统。以密钥管理模块作为数据处置原点,借助信息传输信道,将该元件分别与协议处置结构及协商解密服务单元相连,完成加密系统的硬件运行环境搭建。在此基础上,分析密钥信息的实际协商需求,再根据加密处理的具体任务条件,建立完善的协议加密报文收发处置流程,实现加密系统的软件运行环境搭建,结合相关硬件执行设备,完成基于同态映射的密钥协商协议加密系统设计。对比实验结果表明,与OAuth型加密法则相比,应用新型协议加密系统后,协议数据单向存储极限值超过6.8×10^13 T,密钥组织间的信息转化匹配率也达到81%,大幅提升了相邻密钥组织间的协议数据转存安全性。In order to alleviate the problem of low security of data transfer between adjacent key organizations,a key negotiation protocol encryption system based on homomorphic mapping is designed.With the key management module as the origin of data processing,and with the help of the information transmission channel,the component is connected to the protocol processing structure and the negotiation and decryption service unit respectively to complete the hardware operation environment construction of the encryption system.On this basis,the analysis of the actual negotiation of key information needs,and then based on the specific task of encryption processing conditions,establish the perfect encryption protocol message sending and receiving the disposal process,realize the software running environment of the encryption system,combining with the relevant hardware equipment,complete the key agreement protocol encryption system design based on homomorphic mapping.The experimental results show that compared with OAuth encryption method,after the application of the new protocol encryption system,the one-way storage limit of protocol data exceeds 6.8×10^13 T,and the matching rate of information transformation between key organizations reaches 81%,which greatly improves the security of protocol data transfer between adjacent key organizations.
