摘要
可见光通信(Visible Light Communication,VLC)是解决现有射频通信频谱稀缺问题的关键技术之一。相对于传统RF通信,VLC具备更好的安全性,但若将其应用于大型公共场所,则容易出现VLC链路遭窃听的情况。基于此,对具体的物理层安全优化与加密技术展开分析,提出一些思路和方法,以达到有效提高通信安全防护水平、切实保证VLC系统的安全性的目的。
Visible light communication is a key supplementary technology to solve the problem of scarcity of existing radio frequency communication spectrum.Relying on the line-of-sight link is significantly better than traditional RF communication.But what needs to be considered is that the VLC channel still has a broadcast nature,so if it is used in a large public place,it is prone to eaves dropping on the VLC link.Based on this,the specific physical layer security optimization and encryption technology are analyzed,and some ideas and methods are put forward to achieve the purpose of effectively improving the level of communication security protection and effectively ensuring the security of the VLC system.
