工业边缘侧即插即用设备可信接入研究

Research on Trusted Access to Industrial Edge-Side Plug-and-Play Devices

随着工业互联网和智能制造相关技术的发展,工业边缘侧终端设备数量不断增长。海量异构终端设备接入给工业互联网及其边缘计算环境带来了挑战。为解决越来越重要的边缘计算安全问题,尤其是工业边缘侧即插即用设备的可信接入问题,创新性地将工业即插即用技术成熟度从低到高划分为四个级别(L1~L4),并针对L3的工业边缘侧即插即用设备提出了一种结合可信接入身份认证及信任度评估的可信接入验证方法。基于鼎捷云服务平台,对工业边缘侧即插即用设备的可信接入进行验证。研究结果可应用于网络协同制造平台,也为后续L4级别即插即用设备可信接入标准和方案研究奠定基础,推动了离散行业数字化转型。

With the development of industrial Internet and smart manufacturing related technologies,the number of industrial edge-side terminal devices is growing.The massive access to heterogeneous end devices brings challenges to the industrial Internet and its edge computing environment.To solve the increasingly important edge computing security issues,especially the trusted access of industrial edge-side plug-and-play devices,the maturity of industrial plug-and-play technology is innovatively divided into four levels(L1~L4)from low to high,and a trusted access verification method combining trusted access authentication and trust degree evaluation for L3 industrial edge-side plug-and-play devices is proposed.Based on the Dingjie cloud service platform,the trusted access of industrial edge-side plug-and-play devices is verified.The research results can be applied to the network collaborative manufacturing platform and lay the foundation for the subsequent research on trusted access standards and solutions for L4-level plug-and-play devices,and can promote the digital transformation of discrete industries.
