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 …

Recent Searchable Symmetric Encryption (SSE) schemes enable secure searching over an
encrypted database stored in a server while limiting the information leaked to the server …

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

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 …

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 …

Outsourcing data to the cloud has become prevalent, so Searchable Symmetric Encryption
(SSE), one of the methods for protecting outsourced data, has arisen widespread interest …

Recent foundational work on leakage-abuse attacks on encrypted databases has
broadened our understanding of what an adversary can accomplish with a standard leakage …

We present PANCAKE, the first system to protect key-value stores from access pattern
leakage attacks with small constant factor bandwidth overhead. PANCAKE uses a new …

We present a range of novel attacks which exploit information about the volume of answers
to range queries in encrypted database. Our attacks rely on a strategy which is simple yet …
