摘要

随着逆变器在网络物理环境中变得更加智能,逆变器的网络安全变得非常重要。然而,智能逆变器的固件安全性对各种攻击载体的固件攻击的研究较少。本文提出了一种安全的固件更新和设备认证方法,该方法使用基于区块链的公钥基础设施(PKI)管理系统和智能逆变器中的物理不可克隆功能(PUF)嵌入式安全模块。实验验证了该方法的有效性。

Secure Firmware Update and Device Authentication for Smart Inverters using Blockchain and Phyiscally Uncloable Function (PUF)-Embedded Security Module
Cybersecurity of inverters has been significantly important as inverters become smarter in cyber-physical environments. However, firmware security of smart inverters against firmware attacks from various attack vectors has been less studied. This paper proposes a secure firmware update and device authentication method using a blockchain-based public key infrastructure (PKI) management system and a physically unclonable function (PUF)-embedded security module in a smart inverter. The proposed method is validated by experiments.
