Abstract

Now day cloud computing is reaching the people with very efficiently and quickly because of advantages of cloud computing. Cloud has a nature of low preservation which will gives an efficient result to share the resources with user group in cloud. Important issues in public cloud is share documents and data related on control policies of fine grained access, because of regular change of the data membership sharing in dynamic groups to protect data and privacy identity from cloud that is unfaithful one is still critical problem. The changing membership is important issue when multi owner type of cloud computing, because protecting data and individuality privacy. By using group signature and techniques of dynamic broadcast encryption, any user can secretly share data with other user. The important aim is to gives many-owner data distributing by secure way with dynamically form groups. KP-ABE (Key Policy Attribute Based Encryption) scheme is proposed chose dynamic AA (Attribute authorities). By using the group signature, dynamic transmit and signed receipts, cloud user can namelessly distribute data with other user. This approach is used to reduce computation cost, encryption and overhead of storage. Using this approach any can share a data with other user
