摘要
针对无线传感器网络数据汇聚与传输过程面临的安全威胁,文中提出一种基于安全数据汇聚与信息重构的多路由数据传输算法——MDT.该算法允许网络中存在妥协节点,也允许丢失部分数据.通过理论分析与仿真实验,证实该算法在不增加网络整体能耗的前提下,能有效地抵御侦听、数据篡改和拒绝服务攻击,全面提高系统的安全性和可靠性.
In order to solve the problem of data aggregation and data transmission in wireless sensor network, a Mul- tipath Data Transport （MDT） algorithm based on secure data aggregation and data reconstruction was proposed in the paper. The algorithm allows the network nodes exist in a few compromises, but also allows the loss of part of the data. The theory analysis and simulation result showed that the sensor network with the MDT algorithm could protect against availably eavesdropping, data tampering and Denial of Service attacks. The security and reliability of the network were improved.
