RBACA: role-based access control architecture for multi-domain cloud environment

摘要

Cloud computing is an emerging area as a new arrangement of wide-area distributed computing. Sharing of resources and services over the network are heterogeneous, dynamic, and multi-domain. Security issue is also a serious problem in a cloud computing environment. Similarly, access control and authorisation are an important aspect of the security. The paper proposes a scalable access control architecture and authorisation, for cloud computing environment. A new access control architecture is proposed which is based on traditional access control, role-based access control (RBAC) model. The paper provides a flexible framework for policy announcement management approach for a multi-domain cloud environment. A policy language (XACML) is used for the demonstration of access control policies. This provides a general and standard provision of different resources and services.
