Title: Secure Query Computation with Data Interoperability in a Cloud
Database Environment

Abstract:
In this talk, we will address a security issue in a cloud database
system. In such a system, the user/data owner (DO) exports its data to a
cloud of a service provider (SP), which offers a database service. To
provide data security, highly sensitive data is encrypted by the DO
before it is uploaded to the database at the SP, and the SP is not
trusted to have information about the encryption. In order for the SP to
process queries on the encrypted data, we need homomorphic encryption,
which allows computations to be done on encrypted data without knowing
the data content. Existing homomorphic schemes cannot answer SQL-like
queries that involve operations of many kinds. We propose and design a
secure query database system on relational tables and a set of primitive
operators on encrypted data that allow data interoperability. This is
the first system that allows SQL-like queries to be processed on
encrypted data. We prove that the encryption scheme is secure against a
defined security model. Through experiments, we show that computation on
the DO is minimal and most of the computation is done on the SP.  Hence,
this is a good-fit model for cloud database.
