摘要: Sybil攻击是一种对无线传感器网络(WSN)危害巨大的攻击方式,它破坏WSN中的数据融合、公平资源分配等机制。为此,提出一种基于HCRL的Sybil攻击检测方案。该方案基本思想是Sybil节点创建的多个身份只拥有同一个物理位置,通过对HCRL算法的优化检测出Sybil节点。Sybil攻击对网络性能影响严重,而加入检测方案后网络性能有较大提升。通过仿真实验和性能分析证明了该方案的有效性和低系统开销。

Abstract: Sybil attack is a particularly harmful attack against Wireless Sensor Networks(WSN). They defeat many functions of the WSN such as data fusion, fair resource allocation etc. So it is important to defense and detect Sybil attack. This paper presents a solution scheme for Sybil attack detection based on the Hop-Count-Ratio Localization(HCRL). The main idea of this scheme is that the identities the Sybil nodes created have the same physical location, so the Sybil nodes can be detected through the HCRL optimization algorithm. Sybil attack has a significant influence on the network performance and the network performance is obviously improved after the detection. Simulation experiment and performance analysis shows that the scheme is effective and low-overhead.

Key words: Wireless Sensor Network(WSN), Sybil attack, attack detection, Hop-Count-Ratio based Localization(HCRL) algorithm
