The 5th generation of mobile communications system (5G) virtual private network carrying power business not only increase system capacity, but also bring new security challenges due to the openness. Conducting security analysis on wireless power systems can effectively identify security risks and guide the design of subsequent security protection strategies. However, existing methods lack targeted framework construction and fail to provide intuitive quantitative evaluations. In this paper, a security risk assessment method for power 5G virtual private network is proposed based on the characteristics of power business. On the basis of building the assessment indicators framework, the analysis of security risks is conducted from subjective and objective aspects through analytical hierarchy process and entropy value method. Finally, the effectiveness and applicability of the proposed safety risk assessment method is proved through example analysis.
