The access control mechanism in LoRa has been proven to have high security risks. In order to improve the secure access ability of LoRa terminals, this paper presents a physical layer-based authentication system for security enhancement. Different from the security access technology of cryptography, a lightweight gateway architecture called LW-LoRaWAN is proposed to realize a data frame-based authentication with radio frequency fingerprint (RFF). A novel RFF feature of Cross Power Spectral Density (CPSD) is used to achieve a fast authentication with one single frame. Theoretical analysis and experimental results show that the proposed system not only reinforces the authentication security of LoRa network but also protects the LoRa terminals against the Sybil attacks. The LW-LoRaWAN provides new security approach from physical layer for LoRa network.

基于 LoRa 的轻量级安全访问增强系统

LoRa 中的访问控制机制已被证明具有很高的安全风险。为了提高LoRa终端的安全接入能力,本文提出了一种基于物理层的身份验证系统,以增强安全性。与密码学的安全接入技术不同,提出了一种称为LW-LoRaWAN的轻量级网关架构,通过射频指纹(RFF)实现基于数据帧的认证。交叉功率谱密度 (CPSD) 的一种新颖的 RFF 特征用于通过单帧实现快速身份验证。理论分析和实验结果表明,所提出的系统不仅加强了 LoRa 网络的认证安全性,而且还保护了 LoRa 终端免受 Sybil 攻击。
