Popis:	As the low maintenance, cloud computing supply an capable solution for sharing group resource within cloud users. Sharing data with the two or more owners while preserving data and identity privacy from an un-trusted cloud is still an issue, due to the frequent change of the membership. In this paper, we propose a secure data sharing scheme for dynamic subgroups in the cloud. By using group signature and dynamic broadcast encryption techniques, only privileged cloud user can store and share data. Meanwhile, the storage overhead and encryption computation cost of our scheme are independent with the number of revoked users.
