电力系统下的轻量级自适应认证系统

Lightweight Adaptive Authentication System under Power System

电力物联终端种类繁多,绝大多数处于资源受限的状态下,在实际应用上存在安全需求。本文设计了一种基于LBlock加密算法的挑战应答协议和基于国家商用密码认证方案的轻量级自适应身份认证系统。系统通过树莓派仿真资源受限的电力物联终端测试身份认证以及密钥协商效率与安全性。测试结果表明,该轻量级自适应认证系统可以实现边缘物联代理与各类受限电力物联终端的双向身份认证,有效保证了电力系统自适应认证的需求。

Most power IoT terminals are in a resource constrained state and have security requirements in practical applications.This article designs a challenge response protocol based on LBlock encryption algorithm and a lightweight adaptive identity authentication system based on the national commercial password authentication scheme.The system tests identity authentication,key negotiation efficiency,and security through Raspberry Pi simulation of power IoT terminals with limited resources.The test results show that the lightweight adaptive authentication system can achieve bidirectional identity authentication between edge IoT agents and various restricted IoT terminals,effectively ensuring the demand for adaptive authentication in power systems.
