Abstract: With the continuous commercial use of 5G globally, 5G security has become the focus of attention of all countries. Countries around the world have formulated their own national 5G security strategies, laws and regulations, and academic institutions and think tanks have also formulated standards and strategies. The global 5G development situation and progress are different. Influenced by countries such as the United States and the European Union, the world's major economies have different strategies for 5G supplier selection and technology route. This paper discusses the situation of 5G security at home and abroad in detail, analyzes the main national policies of each country, and makes suggestions on the development and response of 5G in China.

Key words:  , 5G, security, situation, policy, situation, toolbox, strategy, act, progress
