LoRaWAN 是应用于物联网 (IoT) 技术的新型低功耗广域网 (LPWAN) 标准之一。 LPWAN的主要特点是低功耗和远距离覆盖。 LoRaWAN 1.1 规范包括基本的安全方案。但该方案在密钥管理方面还可以进一步改进。本文回顾了LoRaWAN 1.1的安全性，并提出了通过根密钥更新方案增强LoRaWAN安全性。根密钥更新将使 LoRaWAN 中安全密钥的加密分析变得更加困难。分析和仿真表明，与其他密钥导出方案（包括LoRaWAN会话密钥更新中使用的方案）相比，所提出的根密钥更新方案需要更少的计算资源。结果还表明，该方案生成的密钥具有高度的随机性，这是安全密钥的基本要求。
The LoRaWAN is one of the new low-power wide-area network (LPWAN) standards applied to Internet of Things (IoT) technology. The key features of LPWAN are its low power consumption and long-range coverage. The LoRaWAN 1.1 specification includes a basic security scheme. However, this scheme could be further improved in the aspect of key management. In this paper, LoRaWAN 1.1 security is reviewed, and enhanced LoRaWAN security with a root key update scheme is proposed. The root key update will make cryptoanalysis of security keys in LoRaWAN more difficult. The analysis and simulation show that the proposed root key update scheme requires fewer computing resources compared with other key derivation schemes, including the scheme used in the LoRaWAN session key update. The results also show the key generated in the proposed scheme has a high degree of randomness, which is a basic requirement for a security key.
