摘要:

使用5G的系统预计将用于社会5.0和工业4.0的各种情况,如智能城市,智能工厂和关键基础设施。这些系统对我们的生活至关重要,因此必须防止对系统的网络攻击。在本文中,我们解决了5G功能带来的两个问题:使用多供应商设备的系统构建和软件化功能。具体而言,存在供应链风险,即在施工阶段使用恶意设备。此外,软件化的网络功能比硬件更容易受到攻击。为了解决这些问题,我们提出了一种架构概念,包括区块链来记录包括供应链信息在内的安全事件,以及篡改检测引擎来确保5G系统中软件组件的完整性。我们实现了该体系结构的初始原型,并表明其可行性。

英文摘要:

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.
