WebFeb 6, 2024 · Cryptdb是MIT的计算机科学和人工智能实验室(CSAIL)的一个研究项目，其性质可以理解为数据库代理，旨在保护数据库数据。通过随机性加密、确定性加密、同态加密、保序加密等手段，实现了在密文层级处理SQL请求的功能。 WebCryptDB dynamically adjusts the encryption level for each data item at runtime, so as to achieve the maximum privacy level given the user's queries. In particular, CryptDB initially encrypts all data with the strongest level of encryption, and, as the application issues SQL queries, CryptDB adjusts the level of encryption on the
