CryptDB: Processing Queries on an Encrypted Database.

The article presents CryptDB, a system which enables the use of SQL queries over encrypted data and can provide confidentiality for applications which use database management systems (DBMSes). The authors argues that CryptDB addresses threats from adversaries who gain access to or control of DBMS servers or applications, presenting information on the system architecture. The article examines how CryptDB can perform query processing on encrypted databases, SQL-aware encryption, and computing joins supported by CryptDB.
