Semantic Based Authorization Framework For Multi-Domain Collaborative Cloud Environments

:Currently, organizations are growing and continuously improving their services while reducing budget in a competitive market. This is achieved by reusing existing well designed and proved services delivered by third parties in the cloud. Additionally, multi- domain collaborative cloud environments are a promising approach that enables to build and deliver new adaptive, distributed and reliable services. In this case, the data interoperability, the process interoperability and the security open new challenges and issues. In this paper, we propose semantic-based decision making process and consistent with XACML architecture to deal with contextual access control in multi-domain collaborative cloud environments.
