Abstract

Recently, there has been significant enthusiasms in exploiting physical (PHY-) layer characteristics for secure wireless communication. However, most existing PHY-layer security paradigms are information theoretical methodologies, which are infeasible to real and practical systems. In this paper, we propose a weighted fractional Fourier transform (WFRFT) pre-coding scheme to enhance the security of wireless transmissions against eavesdropping. By leveraging the concept of WFRFT, the proposed scheme can easily change the characteristics of the underlying radio signals to complement and secure upper-layer cryptographic protocols. We demonstrate a running prototype based on the LTE-framework. First, the compatibility between the WFRFT pre-coding scheme and the conversational LTE architecture is presented. Then, the security mechanism of the WFRFT pre-coding scheme is demonstrated. Experimental results validate the practicability and security performance superiority of the proposed scheme.
用加权分数傅里叶变换证明物理层的安全性
最近,人们对利用物理层特性进行安全无线通信有着极大的热情。然而,现有的物理层安全范式大多是信息理论方法,在实际系统中并不可行。本文提出了一种加权分数傅里叶变换(WFRFT)预编码方案,以提高无线传输的防窃听安全性。通过利用WFRFT的概念,所提出的方案可以很容易地改变底层无线电信号的特征,以补充和保护上层加密协议。我们展示了一个基于lte框架的运行原型。首先,给出了WFRFT预编码方案与会话式LTE架构的兼容性。然后,对WFRFT预编码方案的安全机制进行了论证。实验结果验证了该方案的实用性和安全性能的优越性。
