摘　　要：尽管无线通信能够带来有线通信无可比拟的好处,但是无线通信天然的多径时变的特性使其比有线通信更容易受到网络攻击。主要集中于无线网络中的物理层安全问题,提出了一种基于随机频谱扩展的无线通信结构。这种通信结构采用一种新的基于Quorum系统的发送端和接收端连接建立方案,能够保证发送端和接收端在一定的时间内建立连接。同时这种通信结构能够提高数据传递过程中的抗攻击能力,能够提供高速和稳健的数据传递。仿真表明该方案能有效提高无线网络的安全性。Although there is no doubt that using wireless communications offers significant benefits over wired connections,but because of the property of multi-path and time variance,the wireless technology introduces additional vulnerability in terms of network security. This work addresses physical layer security,a topic that has been hardly investigated in the smart grid domain. As a promising solution to physical security,a random spread-spectrum based wireless communication scheme is described. This new scheme adopts a new system based on Quorum to connect the sender and the receiver and guarantee a connection in predefined time. At the same time,this communication structure can improve the data transmission process of anti attack ability and can achieve both fast and robust data transmission. Simulation results verifies the effect of the proposed method.
