TITLE : A Hybrid Cloud Approach for Secure Authorized Deduplication
ABSTRACT: Data deduplication is one of important data compression techniques for eliminating duplicate copies of repeating data, and has been widely used in cloud storage to reduce the amount of storage space and save bandwidth. To protect the confidentiality of sensitive data while supporting deduplication, the convergent encryption technique has been proposed to encrypt the data before outsourcing. To better protect data security, this paper makes the first attempt to formally address the problem of authorized data deduplication. Different from traditional deduplication systems, the differential privileges of users are further considered in duplicate check besides the data itself. We also present several new deduplication constructions supporting authorized duplicate check in hybrid cloud architecture. Security analysis demonstrates that our scheme is secure in terms of the definitions specified in the proposed security model. As a proof of concept, we implement a prototype of our proposed authorized duplicate check scheme and conduct tested experiments using our prototype. We show that our proposed authorized duplicate check scheme incurs minimal overhead compared to normal operations.

Traffic class priority based rate control algorithms have been proposed by Yaghmaee et al. for congestion avoidance and these are based on the rate difference at a given node.

Though the proposed algorithms are validated on a fixed topology, they are also valid for the general topology of WSN. The proposed algorithms have been implemented in NS3 platform and the performances of the algorithms have been found to be superior to those of counterpart techniques.
