Role Based Access Control Mechanism in Cloud Computing Using Co - Operative Secondary Authorization Recycling Method
Cloud Computing provides the people the way to share distributed resources and services that belongs to different organization or sites. In cloud computing at present there is no authorization recycling approach. The aim of the work is to develop an authorization recycling approach using CSAR (Co-operative Secondary Authorization Recycling) in Cloud computing Systems. By this each application server recycles previously received authorizations and shares them with other application servers to mask authorization server failures and network delays. The CSAR approach exploits the increased hit rate offered by a co-operative cache of access control decisions.
