SDT安全方案在无线传感器网络的运用研究

Research on SDT Security Scheme for Wireless Sensor Network

克服无线传感器范围限制的方法是依靠中继节点进行数据聚合,关键问题是如何保证点到点的安全传输.提出分段数据传输(Subsection Data Transport,SDT)安全方案,依靠多条路由确保数据能安全地聚合.通过仿真实验,证明该方案具有良好的安全性,即使存在妥协节点,也能有效地抵御偷听、数据篡改和拒绝服务(Denial of Service,DoS)攻击.

A common approach to overcome the limited of sensor networks is to aggregate data relying on intermediate nodes.The pivotal issue is to guarantee end-to-end secureity transmitsion.In the paper,Subsection Data Transport security scheme is presented.Data are safely aggregated relying on multipath routing.The scheme has better security in the simulation.A sensor network can protection against availably eavesdropping,data tampering and Denial of Service attacks even in the presence of compromised nodes.
