基于RSSI无线传感网络的Sybil攻击检测技术研究

Research on RSSI-based Sybil Attack Detection for Wireless Sensor Networks

基于测距RSSI的定位原理,分析了Sybil攻击特点,提出了利用RSSI比率和设置门槛来检测Sybil攻击的安全定位技术。研究表明,由于RSSI的时间差异或者是由于传输率的非对称性引起的不可靠性,用RSSI从不同接收节点的比率值就可以解决这些问题。试验结果表明了本文提出的检测方法具有很好的安全性。

In the light of the detection technique based on RSSI and the attack characters of Sybil, this paper put forward a security location technique to measure Sybil attack by making use of RSSI ratio and setting a threshold. The research shows that although RSSI is time-varying au- thentic and ratio transmission is non-isotropic, using ratio of RSSL from different receivers is feasible to cope with these problems. The emulation result demonstrates the good secusity of the ex- amination method.
