外滩大会发布《密态计算白皮书》 ：低成本密态计算已规模化落地

Core Insights - The release of the "Homomorphic Computing Technology White Paper" by 16 leading academic and research institutions marks a significant step in promoting the application of homomorphic computing in the industry, highlighting its potential as a new generation of data security infrastructure capable of large-scale commercial deployment [1][3] Cost and Performance - Traditional perceptions of high costs associated with homomorphic computing are challenged, as the actual performance is now close to that of plaintext computing. The cost of general homomorphic computing has dropped to below 1.5 times that of plaintext distributed computing, while the cost for homomorphic large model inference is now under 1.2 times that of traditional plaintext inference [3][4] Technological Innovations - Significant cost reductions are attributed to innovations in both technology architecture and infrastructure. The introduction of hardware trust roots and optimized cryptographic protocols has transformed network interaction and computing models, leading to lower computing costs [4] Trust Mechanism Shift - Homomorphic computing facilitates a shift from "subject trust" to "technology trust" in data circulation. This change addresses the limitations of traditional information systems where data is only shared with trusted individuals, thus expanding the scope of data flow and preventing data misuse [4][5] Security Scope - The latest homomorphic computing technology extends security measures across the entire data lifecycle, from identity authentication and access control to key management, ensuring comprehensive protection throughout data aggregation, transmission, storage, computation, and result return [5] Industry Applications - Homomorphic computing has been successfully implemented in various sectors, including government, healthcare, and agriculture. Notable projects include the "Farmer Instant Loan" initiative, which utilizes homomorphic computing for secure data integration, benefiting over 7.6 million farmers [5] Open Source and Standardization - Leading industry players are collaborating to establish unified standards and open-source core frameworks, aiming to create a common security assessment system. The establishment of the "Yin Language Open Source Community" by Ant Group, in partnership with various institutions, is a step towards advancing privacy-preserving computing technology and enhancing interoperability [5]
