The 39th Biannual IPP Symposium

Authentication of Outsourced Storage

David Croston, IAM Technology

This talk will present a collaborative project between Brown's Center for Geometric Computing and IAM Technology that is aimed at developing a general method and a practical application for maintaining authenticated files in an untrusted network storage service. The authentication process is managed by an application external to the storage service and can work with a variety of online storage services since it is independent from the specific storage technology used. Experimental results show that our integrity verification method is efficient and that the overhead due to authentication is negligible.
