物联网设备在未来电力领域（称为智能电网）的使用具有许多好处，例如提高电力系统的可靠性，增强SCADA（监控和数据采集）的功能，改善对运营电网资产的监控和管理，以及先进的计量基础设施。智能电网概念依赖于高速可靠的通信网络技术的集成，以提供双重好处-一是现有电网和智能信息系统之间的互联，另一个是通过物联网设备实现实时电网监控。然而，由于设备成本和安全通信要求之间的权衡，物联网设备本身的安全性是一个挑战。此外，当前的电网需要稳健且安全的无线通信基础设施来实现向智能电网的转变。5G网络被认为是电网数字化的推动者，并促进未来智能电网的物联网连接，具有低延迟，超高速和提高可靠性等多个优点。然而，公共5G网络的使用可能会给基于物联网的智能电网基础设施带来新的安全风险。本文从物联网智能电网的角度分析了3GPP标准组织发布的5G安全规范的安全方面。特别是，我们考虑利用5G作为无线通信基础设施的智能电网场景，并在几个安全方面（如身份验证、机密性、完整性、弹性和可用性）提供5G优势。此外，我们还概述了来自受损的5G网络相关基础设施的物联网智能电网的安全风险。
The use of IoT devices in the future electricity domain (known as the smart grid) has numerous benefits, such as improved reliability of the power system, enhanced functions of SCADA (Supervisory Control and Data Acquisition), improved monitoring and management of operational power grid assets, and advanced metering infrastructure. The smart grid concept relies on the integration of high-speed and reliable communication networking technologies in order to provide twofold benefits - one for the interconnection between the existing power grid and intelligent information systems, and another for enabling real-time grid monitoring via IoT devices. However, the security of IoT devices themselves is a challenge due to the trade-off between device cost and secure communication requirements. Further, current electricity grids require robust and secure wireless communication infrastructure to realize transformation to smart grids. The 5G networks are considered as an enabler for digitalization of power grids and facilitating IoT connectivity for future smart grids with several benefits such as low latency, ultra high speed, and improved reliability. However, the use of public 5G networks may introduce new types of security risks to the IoT-based smart grids infrastructure. In this paper, we analyze the security aspects of 5G security specifications released by the 3GPP standards organization from the perspective of IoT-based smart grids. In particular, we consider a smart grid scenario utilizing 5G as a wireless communication infrastructure, and present 5G benefits to several security aspects such as authentication, confidentially, integrity, resiliency, and availability. Further, we outline security risks to IoT-based smart grids originating from compromised 5G network-related infrastructure.
