无线物理层信息安全探析

Information Security Analysis of the Wireless Physical Layer

在无线传输的过程中,通信的信号往往容易被第三方窃听,为了防止这类情况出现,利用多波束发射技术可以减少的人工噪声干扰,能够物理层安全通信信息的安全,在信号的发送端将信号和人工噪声同时发送,通过天线加权调整信息的方向图主瓣的接收方位,能够有效的消除噪声干扰。

In the wireless transmission process,the communication signal is often easy to be third-party eavesdropping,in order to prevent such a situation,the use of artificial noise can be reduced by the multi-beam emission technology,can the physical layer of the secure communication of information security,the signal sender signal and artificial noise,while sending,receiving orientation of the antenna pattern main lobe of the weighted information,can effectively eliminate noise interference.
