Secure Multi-Owner Data Sharing for Dynamic Groups through Fine Grained Access Control in Cloud Computing

Abstract

One of the biggest concerns with cloud data storage is that of data integrity verification at un trusted servers. To preserve data privacy, a basic solution is to encrypt data files, and then upload the encrypted data into the cloud. To resolve this problem recently the best efficient method MONA presented for secured multi owner data sharing in however we identified some limitations in the same approach in terms of reliability and scalability. Hence in this paper we are further extending the basic MONA by adding the reliability as well as improving the scalability by increasing the number of group managers dynamically.
