摘要
随着目前通信技术的飞速发展, 保密通信在整个现代通信系统中已经得到了非常广泛的应用。近年来, 各种网络监听设备和监听手段层出不穷, 造成了比较严重的损失, 在通信过程中, 关键问题是保证密钥不被识破。介绍了物理层安全技术基本概念, 分析了当前通信保密性技术及安全性技术, 论述安全编码技术、密钥技术、协作干扰技术、信道估计技术等, 详细分析协作干扰的物理层安全技术在保密通信系统中的应用实现, 并给出了验证方案, 提出基于其在防窃听、抗干扰等领域的应用。分析表明, 及时的协作干扰物理层安全是整个信息通信安全防护体系中最重要的组成部分, 能对通信安全进行有效的保障。
Abstract
With the rapid development of communication technology, secure communication has been widely used in modern communication systems. In recent years, all kinds of network monitoring equipment and monitoring means have emerged in an endless stream, resulting in a serious loss, in the process of communication, the key problem is to ensure the key is not to recognize. This paper introduced the basic concepts of physical layer security technology, analysis the current secure communication technology and safety technology, discusses the secure coding techniques, key technology, cooperative jamming technology, channel estimation technology, collaboration interference is analyzed in detail the physical layer security technology in secure through application of credit system in implementation, and gives the verification scheme, is proposed based on its application in the field of anti eavesdropping and jamming. The analysis shows that the timely coordination of physical layer security is the most important part of the whole information communication security protection system, and it can effectively guarantee the communication security.
