Cloud computing is recognized as an alternative to traditional information technology due to its intrinsic resource-sharing and low-maintenance characteristics. In cloud computing, the Cloud Service Providers (CSPs), such as Amazon, are able to deliver various services to cloud users with the help of powerful datacenters. In this paper, the authors 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 multi-user group.
