基于单证人节点的分布式节点复制攻击检测

Single-witness-based distributed detection for node replication attack

在无线传感网络中,现有的节点复制攻击检测方法存在检测率低、通信消耗高、存储消耗高等问题。该文提出一种基于单证人节点的分布式节点复制攻击检测(singlewitness-based distributed detection,SWDD)方法。SWDD方法分为选择证人节点、生成声明信息、发送声明信息、验证证人节点和检测复制节点5个步骤。SWDD方法中引入单证人节点选择机制,采用随机数作为位置声明信息,利用多重映射机制进行证人节点验证,并由最终证人节点完成对复制节点的检测。在OMNeT++平台上进行仿真实验,结果表明:SWDD方法在检测率、通信消耗和存储消耗方面均优于SDC(single deterministic cell)和P-MPC(parallel multiple probabilistic cells)方法。

Existing approaches for detecting node replication attacks in wireless sensor networks have low detection rates, high communication costs and high memory costs. This paper presents a single-witness-based distributed detection （SWDD） method to node replication attacks. This method consists of 5 steps： selecting a witness node, generating the declaration information, sending the declaration information, verifying the witness nodes, and detecting the replication node. The method has a single witness node selection mechanism, uses random numbers to describe the node location, verifies the witness nodes using a multiple mapping mechanism and finally detects the replication nodes by the ultimate witness node. Simulations on OMNeT ＋＋ comparing this method with the single deterministic cell （SDC） and parallel multiple probabilistic cells （P-MPC） methods show that the SWDD method has a better detection rate, less communications and less energy consumption.
