Secure and Oblivious Cloud Storage and Deletion

June 1, 2014 - August 1, 2019

Cloud based storage services are increasingly being used by consumers for their enterprise storage needs. Cloud storage service should provide confidentiality and integrity along with high availability and reliability. These often contradicting requirements results in research challenges that this project aims to address.

This project addressed the open issues with developing an Oblivious Cloud storage architecture.

This project was a joint collaboration between UMBC and USNA. This project was sponsored by Office of Naval Research.
