Abstract
Data sharing and low maintenance, provides a better computing, with the characteristics of intrinsic utilization of resources. In cloud computing, cloud service providers offer an abstraction of infinite storage space for clients to host data. It can help clients reduce their financial overhead of data managements by migrating the local managements system into cloud servers. propose a secure data sharing scheme, which can achieve secure key distribution and data sharing for dynamic group. In this project provide a secure way for key distribution without any secure communication channels. The users can securely obtain their private keys from group manager without any Certificate Authorities due to the verification for the public key of the user. The existing scheme can achieve fine-grained access control, with the help of the group user list, any user in the group can use the source in the cloud and revoked.
