The increasing volume of personal and sensitive data being harvested by data controllers
makes it increasingly necessary to use the cloud not just to store the data, but also to …

Abstract In Dynamic Symmetric Searchable Encryption (DSSE), forward privacy ensures that
previous search queries cannot be associated with future updates, while backward privacy …

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

Applications today rely on cloud databases for storing and querying time-series data. While
outsourcing storage is convenient, this data is often sensitive, making data breaches a …

Volume leakage has recently been identified as a major threat to the security of
cryptographic cloud-based data structures by Kellaris\em et al. CCS'16 (see also the attacks …

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

We initiate the study of structured encryption schemes with computationally-secure leakage.
Specifically, we focus on the design of volume-hiding encrypted multi-maps; that is, of …

Searchable encryption (SE) provides cryptographic guarantees that a user can efficiently
search over encrypted data while only disclosing patterns about the data, also known as …

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 …
