FHE
Quantum-Resistant
抗量子
gene-spafford discussed fully homomorphic encryption (FHE) technology in blog, analyzing its potential for realizing a truly private internet, including encrypted cloud computing, encrypted LLM inference, and confidential blockchain smart contracts.
gene-spafford在博客中探讨了全同态加密(FHE)技术,分析了其在实现真正私有互联网中的潜力,包括加密云计算、加密LLM推理和保密区块链智能合约等应用。
Notes
FHE supports encrypted data direct calculation, with results consistent with plaintext
Current FHE calculation overhead is 1,000x to 10,000x of plaintext operations, storage overhead is 40 to 1,000 times the original text
FHE algorithm improves 8 times per year
FHE is based on lattice cryptography, quantum-resistant
Craig Gentry's bootstrap technology is the key to FHE's ability to perform infinite addition and multiplication
FHE applications will make user data collection-based business models obsolete, achieving 'privacy default' internet
FHE支持加密数据直接计算,结果与明文一致
当前FHE的计算开销是明文操作的1,000x到10,000x,存储开销是原文的40到1,000倍
FHE算法每年以8倍的速度进步
FHE是基于格的密码学,是抗量子的
Craig Gentry的自举技术是FHE能够实现无限次加法和乘法的关键
FHE的应用将使得基于用户数据收集的业务模型变得过时,实现'隐私默认'的互联网
