On the Application of Privacy Computing in the Field of National Cyberspace Security

Privacy computing technology means the collection of technologies that realize data analysis and calculation under the premise of protecting the data itself from external leakage, in order to realize the transformation and release of data value. Privacy computing is applied in different fields such as finance and medical care to assist the technological innovation of the industry. With the continuous virtualization of the cyber world, national cyberspace security has become the focus of development, and the country needs to mine data and establish a market for data elements, and the security of data has become a top priority. In this study, we analyze the present situation of the development of privacy computing technology, including the development status of secure multi-party computing technology, federal learning technology, and trusted execution environment technology, and explore the feasibility of applying privacy computing technology to the national cyberspace security field based on the application of privacy computing technology in several fields, which ensures the reliability of data in the process of data element market circulation, under the Data Security Act With the strong support of the Data Security Act, it is the future development trend to study the integration of a multi-functional new privacy computing technology with the national spatial security field, which is also a strong guarantee to promote people’s privacy security and national stability.
