论文摘要
开放无线电访问网络（O-RAN）是一种有前途的建筑，旨在重塑行业，向开放，自适应和智能运行。在本文中，我们对开放无线电访问网络（O-RAN）进行了全面的安全分析。具体而言，我们回顾了由O-Ran Alliance设计的建筑蓝图，这是细胞生态系统中的主要力量。在安全分析中，我们提供了O-RAN体系结构的详细概述；提出一个本体，以评估系统的安全性，该系统目前处于早期开发阶段；检测到O-Ran的主要风险区域；列举各种威胁行为者对O-Ran；以及对O-Ran的潜在威胁。这项工作的重要性是为蜂窝网络运营商提供了更新的攻击表面。基于攻击表面，蜂窝网络操作员可以仔细部署适当的对策，以提高O-RAN的安全性。
The Open Radio Access Network (O-RAN) is a promising RAN architecture, aimed at reshaping the RAN industry toward an open, adaptive, and intelligent RAN. In this paper, we conducted a comprehensive security analysis of Open Radio Access Networks (O-RAN). Specifically, we review the architectural blueprint designed by the O-RAN alliance -- A leading force in the cellular ecosystem. Within the security analysis, we provide a detailed overview of the O-RAN architecture; present an ontology for evaluating the security of a system, which is currently at an early development stage; detect the primary risk areas to O-RAN; enumerate the various threat actors to O-RAN; and model potential threats to O-RAN. The significance of this work is providing an updated attack surface to cellular network operators. Based on the attack surface, cellular network operators can carefully deploy the appropriate countermeasure for increasing the security of O-RAN.
