物理层安全的非系统性代码

Non-Systematic Codes for Physical Layer Security

Marco Baldi, Marco Bianchi, Franco Chiaraluce

摘要:

本文是第一次研究的主题,实现物理层的安全性,利用非系统信道码。在物理层实现传输安全性的可能性在信息论中已经存在很多年了,但是由于其许多可能的应用,它现在正获得越来越多的兴趣。已经表明,可以有效地利用信道编码技术来设计物理层安全方案,能够确保经历与授权接收器的信道不同的信道的未授权接收器不能收集任何信息。最近,已经提出了利用打孔技术,以减少授权和未授权的信道之间的安全差距。在本文中,我们表明,同样的目标也可以实现通过使用非系统的代码,能够在传输的码字内的信息位加扰。

英文摘要:

This paper is a first study on the topic of achieving physical layer security by exploiting non-systematic channel codes. The chance of implementing transmission security at the physical layer is known since many years in information theory, but it is now gaining an increasing interest due to its many possible applications. It has been shown that channel coding techniques can be effectively exploited for designing physical layer security schemes, able to ensure that an unauthorized receiver, experiencing a channel different from that of the the authorized receiver, is not able to gather any information. Recently, it has been proposed to exploit puncturing techniques in order to reduce the security gap between the authorized and unauthorized channels. In this paper, we show that the same target can also be achieved by using non-systematic codes, able to scramble information bits within the transmitted codeword.
