对基于物理不可克隆函数的智能电网认证协议的分析与改进
Analysis and Improvement of A Smart Grid Authentication Protocol Based on Physical Unclonable Functions
摘要
Abstract
To address identity authentication challenges in smart grid environments,this study conducted an in-depth analysis of the physical unclonable function(PUF)-based authentication protocol proposed by Badar et al.The research revealed that the original protocol was vulnerable to sensor node impersonation attacks and replay attacks.To mitigate these security flaws,an enhanced authentication protocol was designed and implemented.By refining the PUF mechanism and integrating timestamp technology,the vulnerabilities in the original protocol were effectively eliminated.Security analysis demonstrated that the improved protocol resisted various attacks,including physical attacks,impersonation attacks,and replay attacks targeting sensor nodes,while maintaining system operational efficiency.This study provided a secure and efficient solution for identity authentication in smart grid environments.关键词
