基于区块链的配电物联网无线安全接入研究

Research on Wireless Secure Access of Distribution Internet of Things Based on Blockchain

海量异构终端对配电物联网终端安全接入提出了更高的要求,为解决传统身份认证技术带来的一系列安全问题,提出一种利用区块链进行身份认证的配电物联网无线安全接入方案。方案使用区块链技术存储并验证终端身份信息,在实现接入过程去中心化的同时确保终端的安全接入、保障终端身份信息的安全可靠和避免非法节点的接入,有效规避重放攻击、中间人攻击等多种网络攻击行为,满足电力系统对实时性和可靠性的安全需求。

Massive heterogeneous terminals put forward higher requirements for the secure access of distribution internet of things terminals.In order to solve a series of security problems brought by traditional identity authentication technology,a wireless secure access scheme of distribution internet of things using blockchain for identity authentication is proposed.This scheme uses blockchain technology to store and verify terminal identity information.While realizing the decentralization of the access process,it ensures the secure access of the terminal,guarantees the safety and reliability of the terminal identity information,and avoids the access of illegal nodes.It can also effectively avoid multiple network attacks such as replay attacks and man-in-the-middle attacks,and meet the security requirements of power systems for real-time and reliability.
