ZigBee网络按需干扰攻击检测方案

针对ZigBee网络中存在按需干扰攻击破坏网络正常通信的问题,提出一种按需干扰攻击检测方案,通过设计多级序列分配机制和错误比特检测算法,在确定接收信号强度(RSSI)异常错误比特的基础上,对错误比特RSSI进行序贯概率比检验,进而完成按需干扰攻击检测。实验结果表明,该方案可实现95%以上的检测成功率,并具有较小的通信开销和能量消耗。该方案避免了测量网络报文投递率(PDR)、网络拓扑变化等网络参数,实现了对按需干扰攻击的有效检测,增强了ZigBee网络安全性能。

Detection scheme of reactive jamming in ZigBee network

In this work, a reactive jamming detection scheme is proposed to solve the problem that reactive jamming attack disrupts the legal communication of ZigBee network. Multiple class sequence distributing scheme and error bits detecting algorithm are proposed, which could obtain a set of abnormal received signal strength indication (RSSI) of error bits that would be subsequently identified by sequence probability ratio test (SPRT). An evaluation of the proposed scheme is validated experimentally and the results show that the solution is able to detect reactive jamming at success rate above 95% with relatively fewer communication and energy overheads. The measurement of packet delivery ratio (PDR) or topology changes is not considered in the scheme, which achieves effective detection against reactive jamming and enhancing security performance of ZigBee networks.
