Nowadays sharing data among organizations plays an important role for their collaboration. During collaborations, the organizations need to access shared information while respecting the access control constraints. In addition, most organizations rely on cloud based solutions to store their data (e.g. openstack). In such platform, data access is regulated by Access Control Lists (ACLs). ACL defines static access rules. It assumes the knowledge of the whole set of users and possible access requests. This make ACL unusable in collaborative context due to the dynamic nature of collaborative sessions. In this paper, we consider ABAC, a flexible and fine-grained model, as an access control model for cloud-based collaborations to overcome the ACL limitations. We provide an architecture that integrate ABAC in the storage level of a cloud platform. © 2018, ICST Institute for Computer Sciences, Social Informatics and Telecommunications Engineering.
