In this paper, we propose Arx, a practical and functionally rich database system that encrypts the data only with semantically secure encryption schemes. ...
In recent years, encrypted databases have emerged as a promising direction that provides data confidentiality without sacrificing functionality: queries are executed on encrypted data. ...
We propose Arx, a practical and functionally rich database system that takes an important step in this direction by always keeping the data encrypted with semantically secure encryption schemes. ...

In particular, the "snapshot attacker" model used to support the security claims for many encrypted databases does not reflect the information about past queries available in any snapshot attack on an ...
Encrypted databases, a popular approach to protecting data from compromised database management systems (DBMS's), use abstract threat models that capture neither realistic databases, nor realistic attack ...
Because index values are encrypted using standard encryption, the authors claim semantic security against snapshot attacks. ...
