Enhancing Security and Performance by Fragmenting and Deduplication in cloud
Mahesh Kharde,  Ashish Kumar
From last two decades, the appealing features of cloud computing has fueled integration of cloud in the human life. In cloud computing, data is been outsourced to 3rd party, which gives rise to security concerns. Due to attacks by other users and node within cloud, data compromise may occur. In this paper we propose Enhancing technique for cloud Security by Fragmenting and replicating data that collectively approaches the security and performance issues. In this methodology, we break file into pieces (Fragments), and replicate this fragments over the nodes in the cloud. Each nodes consist of single fragment of a particular file that relies us that even any attacker attacks a node, no meaningful information should be exposed to him. We also restrict attackers from guessing location of fragments by separating them using T-coloring algorithm. Data Deduplication plays an important role in reducing storage overhead in our proposed methodology. Since we do not use any traditional cryptography, we avoid performance overhead on data. We show that probability to identify any file is extremely low.
