摘要: Sybil攻击会破坏无线传感器网络的冗余备份、多路径路由等机制,基于INSENS路由协议中的路由建立机制,从事件观测区域到基站建立两条路径,建立第二条路径的同时,利用节点与邻居节点间的距离,以及第一条路径中节点的位置信息检测出Sybil攻击,从而建立绕过Sybil攻击的第二条路径,将事件区域观测到的数据传输给基站。实验表明提出的方法能够使路径有效地绕过Sybil攻击,并且建立的安全路由协议在节点计算量、存储量及能量消耗三方面的性能均低于采用共享密钥进行身份认证的防范和检测Sybil攻击方法中的开销。

Abstract: Sybil attacks can defeat many mechanisms of wireless sensor networks such as redundancy,multi-path routing etc.This paper proposes a scheme for constructing secure routing to bypass misbehavior nodes that launch Sybil attacks.Based on the routing mechanism used in INSENS,the method constructs two paths from the event region to base station,after the first path is built,uses the distances between the node and its neighbors and the location of the nodes in the first path to detect Sybil attacks,then constructs the second routing with bypassing misbehavior nodes which launch Sybil attacks.The simulation results show that the proposed method makes the routing bypass Sybil attacks,and computation,storage and energy consumption are lower than the method using keys sharing and identities certification.

Key words: Sybil attacks, multi-path, INSENS, secure routing
