Enabling Data Dynamics and Achieving Access Control and Assured Deletion in Cloud

Nilam Musale, Vilas Gaikwad

Abstract: In this paper, a new practical cloud storage framework is proposed which is build on FADE system. FADE is cloud storage system which is a practical, implementable and readily deployable. It protects deleted data with policy-based file assured deletion. FADE system is using cryptographic techniques in which it first encrypts the outsourced data files to maintain their privacy and integrity. It also assuredly deletes files to make them unrecoverable to anyone upon revocation of file access policies. A working prototype of FADE is implemented on cloud storage services. We propose two extensions to the basic design of FADE. The first extension is to use attribute based encryption (ABE) to authenticate clients through policy based access control. The second extension is to add third dynamic operation to basic design of FADE architecture known as UPDATE operation.
