For over many decades, relational database model has been considered as the leading
model for data storage and management. However, as the Big Data explosion has …

Users of modern data-processing services such as tax preparation or genomic screening
are forced to trust them with data that the users wish to keep secret. Ryoan1 protects secret …

We analyse the security of database encryption schemes supporting range queries against
persistent adversaries. The bulk of our work applies to a generic setting, where the …

We present attacks that use only the volume of responses to range queries to reconstruct
databases. Our focus is on practical attacks that work for large-scale databases with many …

Encrypted search algorithms (ESA) are cryptographic algorithms that support search over
encrypted data. ESAs can be designed with various primitives including …

Cloud services have revolutionized modern computing. The benefits of outsourcing data and
computation come with security and privacy concerns. This monograph explores the …

Encrypted database systems provide a great method for protecting sensitive data in
untrusted infrastructures. These systems are built using either specialpurpose cryptographic …

Building expressive encrypted databases that can scale to large volumes of data while
enjoying formal security guarantees has been one of the holy grails of security and …

Efficient, leakage-free search on encrypted data has remained an unsolved problem for the
last two decades; efficient schemes are vulnerable to leakage-abuse attacks, and schemes …

We show how to encrypt a relational database in such a way that it can efficiently support a
large class of SQL queries. Our construction is based solely on structured encryption (STE) …
