To improve the quality of medical care and reduce unnecessary medical errors, electronic
medical records (EMRs) are widely applied in hospital information systems. However …

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 …

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

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 …

Hardware enclaves such as Intel SGX are a promising technology for improving the security
of databases outsourced to the cloud. These enclaves provide an execution environment …

Existing oblivious storage systems provide strong security by hiding access patterns, but do
not scale to sustain high throughput as they rely on a central point of coordination. To …

Dynamic searchable symmetric encryption (DSSE) has been widely recognized as a
promising technique to delegate update and search queries over an outsourced database to …

Symmetric Searchable Encryption (SSE) schemes enable users to search over encrypted
data hosted on an untrusted server. Recently, there has been a lot of interest in forward and …

Most cloud service providers offer limited data privacy guarantees, discouraging clients from
using them for managing their sensitive data. Cloud providers may use servers with Trusted …

This paper addresses a key missing piece in the current ecosystem of decentralized
services and blockchain apps: the lack of decentralized, verifiable, and private search …
