Distributed Access Control
Decentralized administration is a salient feature in cloud deployment models.
Decentralization of access control enforcement is desirable.
In centralized solutions, access control for a large number of users over multiple cloud domains must cope with the complexities of maintaining a large number of authorization
rules. Existing solutions describe multiauthority cryptographic access control
models.
However, it’s important to consider the application-specific requirements along with multitenancy and the distributed nature of cloud-based deployments in developing more scalable access control models.
