Project: Extension of the Verifiable Keyword Encrypted Search

Short bio | CV

Research Interests

Optimization theory, operations research, security systems and mathematical modeling.

Project Description

Verifiable search on encrypted files is motivated by the recent surge toward cloud storage. A weak client with storage limitations can delegate the burden of data processing to the cloud. For a secured delegation, a client must have the ability to efficiently verify the results of the server for any arbitrary query.

There are some protocols in the literature dealing with verifiable keyword encrypted search, which can handle verification for a single keyword query. However, these existing protocols do not support expressive queries. On the other hand, there are searchable symmetric encryption (SSE) protocols that do support Boolean queries, but do not have verification component.

The aim of this project is to develop efficient protocols to verifiably perform searches over outsourced encrypted database with full security guarrantee. Specifically, we extend two SSE protocols (OXT and MC-OXT) by adding verification steps. These new verification features would allow a client to efficiently verify whether the server faithfully executed a search operation or not.

This project has real world applications in cybersecurity. For example, ecrypted verifiable search is important during intelligence sharing between two or more disparate groups.

This project is joint work Whitney Drazen .
