| 摘 要： | 传统的网络安全防护中分层加密只涉及到网络的应用层、传输层、网络层和链路层,而在物理层通常没有密码防护。针对这一问题,在阐述物理层加密基本原理的基础上,给出了信道编码加密、调制加密、扩频加密等三种典型的物理层加密方法,从而为空间信息网络安全防护提供了新的方法和思路。

| Abstract: | In traditional network safety measures,the encryption only occurs in application layer,transport layer,network layer and data link layer.But there is not the encryption in physical layer generally.After the basic principle of physical layer encryption is explained,three typical methods are given such as channel code encryption,modulation encryption and spectrum spread encryption.The new ideas for the space information network counter-countermeasures are provided. |
