论文摘要
预计使用5G的系统将用于社会5.0和Industrie 4.0的各种情况，例如智能城市，智能工厂以及关键的基础设施。这些系统对我们的生活至关重要，因此必须防止针对该系统的网络攻击。在本文中，我们解决了由5G功能提出的两个问题：使用多供应商设备和软件功能的系统构建。具体而言，在施工阶段使用恶意设备存在供应链风险。此外，与硬件相比，软件网络功能很容易受到攻击。为了应对这些问题，我们提出了一个组成一个区块链的概念，以记录安全事件，包括供应链信息和篡改检测引擎，以确保5G系统中软件组件的完整性。我们实施了体系结构的初始原型，并显示其可行性。
Systems using 5G are expected to be used in various cases of Society 5.0 and Industrie 4.0 such as smart cities, smart factories, and also critical infrastructures. These systems are essential for our life, thus cyberattacks against the system must be prevented. In this paper, we tackle two problems posed by 5G features: system construction using multi-vendor devices and softwarized functions. Specifically, there are supply-chain risks that malicious devices are used in the construction phase. Moreover, the softwarized network functions are easy to be attacked compared to hardware. To cope with these problems, we propose a concept of architecture comprising a blockchain to record security events including supply-chain information and a tamper detection engine to ensure the integrity of software components in 5G system. We implement the initial prototype of the architecture and show its feasibility.
