Abstract:

In recent years, as one of the key technology paths for data secure circulation, privacy-preserving computing technology has developed rapidly, and it has been widely used in finance, government affairs, medical care, and other scenarios. However, with the development of current privacy-preserving computing technology products, the cross-platform interconnection between privacy-preserving computing platforms with different system architectures or functions has gradually attracted attention. This poses new challenges to the large-scale application of privacy-preserving computing technology. Focusing on this key issue, this paper deeply analyzes the industry’s development from the perspectives of conceptual connotation, implementation path, practical cases, standards, and specifications. It also deeply discusses the future development direction of cross-platform interconnection.

Key words: privacy-preserving computing, cross-platform interconnection, data circulation
