-Cloud computing is an emerging computing paradigm in which resources of the computing infrastructure are
provided as services over the Internet. Sharing group resource among cloud users is a major problem, so cloud computing
provides an economical and efficient solution. Mona, secure data sharing in a multi-owner manner for dynamic groups
preserves data, identity privacy from an unfrosted cloud and allows frequent change of the membership. In this project, we
propose a secure multi owner data sharing scheme, for dynamic groups in the cloud. By leveraging group signature and
dynamic broadcast encryption techniques, any cloud user can anonymously share data with others. Proposing a new
model for Sharing Secure Data in the Cloud for the Dynamic Group.

We have kept IJCERT is a free peer-reviewed scientific journal to endorse conservation. We have not put up a paywall to readers, and we do not charge for publishing. But running a monthly journal costs is a lot. While we do have some associates, we still need support to keep the journal flourishing. If our readers help fund it, our future will be more secure.
