面向物联网的区块链分布式身份认证模型研究

Research on blockchain distributed identity authentication model for the Internet of Things

物联网是物理设备与信息技术的融合与应用,在工业互联网发展中发挥着重要的作用。随着物联网设备的增加,物联网在计算处理和存储等方面的资源受限,集中式的物联网平台兼容性差,且数据得不到有效保障,存在数据泄露等风险,物联网的安全访问面临着巨大的风险与挑战,迫切需要一种适应物联网的身份认证模型保证其安全性。因此,文章基于区块链技术,提出一种面向物联网的分布式身份认证模型,利用分布式身份(Decentralized Identity,DID)为物联网设备注册唯一的身份标识符,该模型适用于物联网环境,保护了物联网设备身份数据的完整性和有效性。

The Internet of Things is the integration and application of physical equipment and information technology,and plays an important role in the development of the Industrial Internet.With the increase of IoT devices,the resources of IoT in computing,processing and storage are limited.The centralized IoT platform has poor compatibility,and data cannot be effectively protected.There are risks such as data leakage.The secure access of IoT is faced with There are huge risks and challenges,and an identity authentication model adapted to the Internet of Things is urgently needed to ensure its security.Therefore,this article proposes a distributed identity authentication model for the Internet of Things based on blockchain technology,using Decentralized Identity(DID)to register unique identity identifiers for Internet of Things devices.This model is suitable for the Internet of Things environment.,protecting the integrity and validity of identity data of IoT devices.
