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 …

Cloud computing facilitates convenient and on-demand network access to a centralized pool
of resources. Currently, many users prefer to outsource data to the cloud in order to mitigate …

We study the problem of dynamic symmetric searchable encryption. In that setting, it is
crucial to minimize the information revealed to the server as a result of update operations …

Recently, various protocols have been proposed for securely outsourcing database storage
to a third party server, ranging from systems with" full-fledged" security based on strong …

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 …

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 …

Secure Multi-Party Computation (MPC) allows mutually distrusting parties to run joint
computations without revealing private data. Current MPC algorithms scale poorly with data …

We study the problem of dynamic searchable encryption (DSE) with forward-and-backward
privacy. Many DSE schemes have been proposed recently but the most efficient ones have …

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 …
