行业白皮书：低成本密态计算已来 实现数据“可用不可见”

Core Insights - The "White Paper on Encrypted Computing Technology" was jointly released by 16 leading academic and research institutions, including Ant Group, Zhejiang University, and the University of Science and Technology of China, at the 2025 Inclusion Bund Conference, aiming to promote the application of encrypted computing in various industries [1][4] Summary by Sections Encrypted Computing Overview - Encrypted computing is defined as utilizing cryptography, trusted hardware, and system security technologies to ensure data is usable but not visible during computation, thereby preventing data leakage and misuse [3] Cost and Performance - The white paper highlights that the common misconception of high costs associated with encrypted computing is outdated, as its performance is now comparable to plaintext computing. The cost of general encrypted computing has dropped to below 1.5 times that of plaintext distributed computing, while the cost for large model inference has decreased to under 1.2 times that of traditional plaintext inference [3][4] Industry Applications - Encrypted computing has been successfully implemented in various sectors, including government, healthcare, and agriculture. Notable projects include the Hangzhou Encrypted Computing Center and the "Farmer Instant Loan" project, which serves over 7.6 million farmers by securely integrating sensitive data [4] Standardization and Open Source - The white paper indicates that leading industry players are collaborating to establish unified standards and an open-source core framework, aiming to accelerate the development and application of privacy-preserving computing technologies [5]
