Description

Abstract:-

In this project user can now outsource data backups off-site to third-party cloud storage services

so as to reduce data management costs. However, we must provide security guarantees for the 

outsourced data, which is now maintained by third parties. We design and implement FADE, a

secure overlay cloud storage system that achieves fine-grained, policy-based access control and

file assured deletion. It associates outsourced files with file access policies, and assuredly deletes

files to make them unrecoverable to anyone upon revocations of file access policies. To achieve

such security goals, FADE is built upon a set of cryptographic key operations that are self-

maintained by a quorum of key managers that are independent of third-party clouds. In particular,

FADE acts as an overlay system that works seamlessly atop today’s cloud storage services.
