Abstract

Data elements play a pivotal role in propelling the growth of the digital economy, especially with the deep and extensive application of artificial intelligence and large models across various sectors, leading to increasingly severe challenges in data security. The conundrum of balancing data utilization with data security, seeking an equilibrium solution to achieve the goal of “usable yet invisible” data, has become a research topic of significant interest in both academic and industrial circles in recent years. Cryptographic technology undoubtedly stands as one of the most effective privacy-preserving solutions in privacy computing, aiming to fulfill data processing requirements and objectives without disclosing sensitive information. This report focuses on the current state and advancements in cryptographic technology research within privacy-preserving computing, further discussing its application fields and directions, along with the team's recent related research efforts, highlighting the challenges faced in theoretical research and technological application.
