论文摘要
5G注定要支持具有超高致密性和低潜伏期的特征的工业物联网（IIT）。 5G利用了更智能的体系结构，无线电访问网络（RANS）不再受基站接近或专有基础架构的约束。第三代合作伙伴项目（3GPP）涵盖了电信技术，包括RAN，核心运输网络和服务功能。 Open Ran Alliance（O-RAN）旨在定义实施和部署体系结构，重点关注开源界面和功能单元，以进一步降低成本和复杂性。基于O-Ran的5G网络可以使用来自不同硬件和软件供应商的组件，促进供应商多样性，互换性和5G供应链弹性。 3GPP和O-RAN 5G都必须管理部署带来的安全性和隐私挑战。许多现有的研究已经解决了每个系统内的威胁和脆弱性。 5G在遵守隐私法规和要求方面也面临着压倒性的挑战，这些挑战需要保护用户可识别的信息。 在本文中，我们研究了3GPP和O-RAN 5G安全性和隐私设计以及已确定的威胁和漏洞。我们还讨论了如何扩展零信任模型，以在5G空气接口和网络组件上提供高级保护。
5G is destined to be supporting large deployment of Industrial IoT (IIoT) with the characteristics of ultra-high densification and low latency. 5G utilizes a more intelligent architecture, with Radio Access Networks (RANs) no longer constrained by base station proximity or proprietary infrastructure. The 3rd Generation Partnership Project (3GPP) covers telecommunication technologies including RAN, core transport networks and service capabilities. Open RAN Alliance (O-RAN) aims to define implementation and deployment architectures, focusing on open-source interfaces and functional units to further reduce the cost and complexity. O-RAN based 5G networks could use components from different hardware and software vendors, promoting vendor diversity, interchangeability and 5G supply chain resiliency. Both 3GPP and O-RAN 5G have to manage the security and privacy challenges that arose from the deployment. Many existing research studies have addressed the threats and vulnerabilities within each system. 5G also has the overwhelming challenges in compliance with privacy regulations and requirements which mandate the user identifiable information need to be protected. In this paper, we look into the 3GPP and O-RAN 5G security and privacy designs and the identified threats and vulnerabilities. We also discuss how to extend the Zero Trust Model to provide advanced protection over 5G air interfaces and network components.
