Proceedings of the 28th ACM International Conference on Information and Knowledge Management, pp. 1331-1340, 2019.
We consider the following secure data retrieval problem: a client outsources encrypted data blocks to a semi-trusted cloud server and later retrieves blocks without disclosing access patterns. Existing PIR and ORAM solutions suffer from serious performance bottlenecks in terms of communication or computation costs. To help eliminate this ...More
