An Efficient Secure Multi Owner Data Sharing for Dynamic Groups in Cloud Computing

In this paper, we present a secure multi owner data sharing scheme for dynamic groups in the cloud computing. By leveraging on group signature and dynamic broadcast encryption techniques, any cloud user can anonymously share data with others. In this propose a new model for Sharing Secure Data in the Cloud computing for the Multiuser Groups. In this one of the biggest concern with cloud data storage is that of data integrity verification at untreated servers. To preserve data privacy, the 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 that same approach in terms of reliability and scalability. Hence in this paper we are further extending the basic MONA by adding the reliability and as well as improving the scalability by increasing the number of group managers dynamically.
