摘要
由于物联网信息传输环境是多向传输环境,不同链路中文件的类型和内容都存在较大差异,传统方法采用单向密钥链的ID认证防御机制,只能对文件的类型进行识别,不能识别文件的内容,导致攻击者能轻而易举的获取系统的权限,随意篡改、泄露用户的隐私信息,出现传输数据精确性下降的问题,给物联网使用者带来极大的安全隐患。提出一种基于物联网信息的复数隐私保护差异数据融合计算方法 CNPD(Complex Number-based Privacy Data Aggregation),主要利用传输数据的复数代数表达方式,在物联网信息传输时以节点向节点发送和接收数据信息时运用数据隐藏进行融合,当数据被窃取时,立刻受到一点一密钥限制,有效保护了窃取数据被恢复敏感信息。保证了物联网信息传输数据的精确性。仿真结果表明,通过使用物联网信息的复数隐私保护差异数据融合计算方法 CNPD,数据融合的速度大大提高,保证了物联网信息传输数据精确性与机密性,具有良好的实用价值。
In the paper,a calculation method of Complex Number- based Privacy Data Aggregation( CNPD)based on the network information was proposed. The algebra expression of complex number of data transmission was used,and in network information transmission,when sending and receiving data information using the way of node to node,data hiding was used to make fusion. If the data are stolen,it is constrained immediately by the one point one key,to effectively ensure that the sensitive information of stolen data is restored,and the accuracy of information transmission data of Io T. Simulation results show that by using the calculation method of Complex Number- based Privacy Data Aggregation( CNPD) of Io T information,the speed of data fusion is greatly enhanced to ensure the accuracy and confidentiality of Io T information transmission data,which has good practical value.
