无线传感器网络中的Sybil攻击与检测

Sybil Attacks and Detects in Wireless Sensor Networks

无线传感器网络中Sybil攻击是一种常见的攻击方式。在Sybil攻击中，一个恶意节点对外的表象是多个传感器节点，即具有多个身份，比如通过冒充其他节点或简单的对外声称伪造的身份。本文系统分析了传感网中Sybil攻击所带来的危害，重点讲述了当前针对Sybil攻击的检测手段，最后给出结论。

Sybil attacks is a harmful threat to wireless sensor networks. In Sybil attacks, a malicious node behaves as if it were a large number of nodes, for example by impersonating other nodes or simply by claiming false identities. This paper first systematically analyzes the threat posed by the Sybil attack to wireless sensor networks,and then describes the detection methods which uses to defeat the Sybil attacks. In the end, we make a conclusion.
