基于放大转发和协作拥塞的窄带物联网物理层安全容量研究
NB-IoT Security Capacity Research in the Physical Based on Amplifer Forward and Cooperative Jamming Strategies
摘要
Abstract
Narrow Band Internet of Things(NB-IoT)technology has developed rapidly in recent years,the security problem is facing a serious challenge with the sharp increase of the number of nodes and the openness of NB-IoT.In view of the problem of serious security threats to the non trusted or eavesdropping nodes of the NB-IoT,it is proposed that the physical layer security can be guaranteed by using the amplify and forward and cooperative congestion strategy of the relay nodes.Amplify and forward relay nodes amplify and forward the source signal,and the cooperative congestion node gives the eavesdropping node a greater interference signal than the destination node,which bring the diversity gain together.Simulation results show that the diversity gain brought by the relay nodes can significantly improve signal quality of receiving nodes,enhance channel and security capacity,and ensure that the eavesdropper can't obtain the useful information even without high layer encryption algorithm.关键词
