摘　　要：针对无线传感器网络数据汇聚中存在的安全威胁问题,提出一种基于多路由传输的安全数据汇聚机制。该机制将传感器节点感知数据分解到不同的维数上,在数据传输过程中采用多路由传输,且在数据传输过程中不必执行解密-加密操作,并从外部攻击和内部攻击对新机制的安全性进行了分析。分析结果表明,该机制能有效抵御侦听、数据分组丢弃、路由分组丢弃等类型的攻击。Aiming at the threats in the process of data aggregation, a secure data aggregation mechanism based on multi-routing transmission for wireless sensor networks is proposed. The data is divided into different dimensions before transmission, and then the divided data are transmitted by means of multi-routing. Meanwhile, the encrypted data do not need to be decrypted in the process of data transmission. The security of the new mechanism is analysed from the aspects of external attacks and insidious attacks. Analysis results show that the wireless sensor networks by means of the new mechanism can effectively protect against eavesdropping, routing packet discarding and data packet discarding.
