Despite a growing body of work on leakage-abuse attacks for encrypted databases, attacks on practical response-hiding constructions are yet to appear. Response-hiding constructions are superior in that they nullify access-pattern based attacks by rev

Cuckoo hashing is a common hashing technique, guaranteeing constant-time lookups in the worst case. Adding a stash was proposed by Kirsch, Mitzenmacher, and Wieder at SICOMP 2010, as a way to reduce the probability of failure (i.e., the probability t

Recent foundational work on leakage-abuse attacks on encrypted databases has broadened our understanding of what an adversary can accomplish with a standard leakage profile. Nevertheless, all known value reconstruction attacks succeed under strong as

We consider a scenario in which a data owner outsources storage of a large graph to an untrusted server; the server performs computations on this graph in response to queries from a client (whether the data owner or others), and the goal is to ensure

Oblivious RAM (ORAM) is a cryptographic primitive that allows a trusted CPU to securely access untrusted memory, such that the access patterns reveal nothing about sensitive data. ORAM is known to have broad applications in secure processor design an

In this work we design new searchable encryption schemes whose goal is to minimize the number of cryptographic operations required to retrieve the result---a dimension mostly overlooked by previous works, yet very important in practice. Our main idea
