Access Pattern Disclosure Attacks against Searchable Encryption Schemes
Presenter: Murat Kantarcioglu (University of Texas at Dallas)

With the advent of cloud computing, outsourcing data to cloud providers is becoming more popular due to the lower cost and increased flexibility. At the same time, concerns related to security of the outsourced data are increasing. To address these concerns, various protocols have been proposed in the literature to outsource data in an encrypted format and execute queries over encrypted data. Oblivious RAM protocols allow access to remote encrypted data without revealing access pattern even to the remote server. Unfortunately, even the most efficient Oblivious RAM protocol is too expensive to be used in most practical applications. Alternatively, a lot of efficient protocols have been proposed in the literature that allow query execution over encrypted data. There are practical Searchable Symmetric Encryption (SSE) techniques that allow keyword search over remote encrypted data. Database-As-a-Service (DAS), on the other hand, allows SQL queries to be executed over remote encrypted data. All these efficient techniques purposefully reveal data access pattern to an adversary for the sake of efficiency.

Dr. Murat Kantarcioglu is an Associate Professor in the Computer Science Department and Director of the UTD Data Security and Privacy Lab at the University of Texas at Dallas. He holds a B.S. in Computer Engineering from Middle East Technical University, and M.S. and Ph.D degrees in Computer Science from Purdue University. He is a recipient of NSF CAREER award and Purdue CERIAS Diamond Award for Academic excellence. Currently, he is a visiting scholar at Harvard Data Privacy Lab.
Dr. Kantarcioglu’s research focuses on creating technologies that can efficiently extract useful information from any data without sacrificing privacy or security. His research has been supported by grants from NSF, AFOSR, ONR, NSA, and NIH. He has published over 100 peer reviewed papers.
Some of his research work has been covered by the media outlets such as Boston Globe, ABC News etc. and has received two best paper awards.
