摘要：5G communication technology provides strong support for the power Internet of Things, and it also introduces new security challenges in the application process of the power industry. Starting from the analysis of the power 5G business requirements, this article proposes five 5G enterprise networking construction plans based on different collaborative processing relationships, and conducts a comparative analysis in security, delay, independence, cost, and staffing. According to the analysis of power business requirements and enterprise networking mode, a hybrid networking architecture of 5G and power communication network is proposed, and the 5G network slicing architecture is re-segmented according to different business scenarios. Finally, the new risks and challenges introduced by 5G technology are analyzed in detail from the four parts of terminal access, edge computing, network channel, and core network. Two important risks pointed are specified through a security risk assessment algorithm. In the future, it is also necessary to further study key technologies such as lightweight authentication algorithms and network slice security isolation to realize the real security use of 5G network in the power industry.
