T-DB：在DBaaS框架下实现全功能透明加密数据库
T-DB: Toward Fully Functional Transparent Encrypted Databases in DBaaS Framework
摘要：
个人和组织倾向于将其数据迁移到云，特别是在数据库即服务（DBaaS）模式中。主要的障碍是保密性和关系数据库的使用之间的冲突。我们通过严格遵循未修改的DBaaS框架的透明数据库（T-DB）系统来解决这个障碍。数据库所有者将加密的数据库外包给云平台，只需要存储加密密钥和数据库的空表头，数据库用户可以像往常一样对加密的数据库进行几乎所有类型的查询，云可以像数据库未加密一样处理密文查询。在真实云环境中的实验表明，T-DB具有良好的查询回答精度和出色的性能。
英文摘要：
Individuals and organizations tend to migrate their data to clouds, especially in a DataBase as a Service (DBaaS) pattern. The major obstacle is the conflict between secrecy and utilization of the relational database to be outsourced. We address this obstacle with a Transparent DataBase (T-DB) system strictly following the unmodified DBaaS framework. A database owner outsources an encrypted database to a cloud platform, needing only to store the secret keys for encryption and an empty table header for the database; the database users can make almost all types of queries on the encrypted database as usual; and the cloud can process ciphertext queries as if the database were not encrypted. Experimentations in realistic cloud environments demonstrate that T-DB has perfect query answer precision and outstanding performance.
