A Survey on Mona: Secure Multi-Owner Data Sharing for Dynamic Groups in the Cloud

Abstract: Cloud computing is the delivery of computing services over the Internet. The present time cloud computing provides us a efficient way to share data amoung cloud users with low maintenance. In this paper we see the secure multiowner data sharing scheme for dynamic groups in cloud computing. And also a secure multiowner data sharing schema by leveraging group signature and using dynamic broadcast encryption techniques any members can share and data with other users. MONA presented for secured multi owner data sharing to resolve the many problem in the cloud computing.Whenever the existing system is revocation of member form group.manager has to generate a new key and then distribute to other members able to upload or download files. So that we need for generating new key each time whenever therisa revocation of members.
