摘要
低功率低损耗网络路由(Routing Protocol for low power and Lossy network,RPL)是无线物联网的典型路由。由于未采用集中安全机制,RPL路由易受女巫攻击。为此,提出基于接收信号强度的防御女巫攻击的RPL路由(RSSI-based against Sybil attack RPL,RSPL)。RSPL路由通过统计接收信号的强度值,并结合邻居节点的观察,估算节点可信度,进而检测攻击节点。同时,利用链路的传输期望次数和链路信任值修改RPL路由中的目标函数,进而阻止攻击节点参与路由。性能分析表明,相比同类算法,提出的RSPL路由降低了检测攻击节点的误检率,提高了数据包传递率。
Routing Protocol for low power and Lossy network(RPL) is a popular protocol used in wireless Internet of Things(IoT) network.However,RPL routing is vulnerable to sybil attacks because it does not adopt a centralized security mechanism.Therefore,RPL routing against sybil attack by received signal strength index-based(RSPL) is proposed in this paper.In RSPL,the reliability of nodes is estimated through the statistics of RSSI,and the attack is detected by neighbor node through their observation.In addition,objective function in RPL is modified by Expected Transmission Count(ETX) and trust of link in order to protect the attack node from participating in the route.Simulation results show that RSPL improves the detection ratio of sybil node and packet delivery ratio compared with other schemes.
