摘要：Highly computational resource sharing environments like grids pose major security issues.
Secure interoperability has been a growing concern for such multi domain computing
systems. Collaboration in such a diverse environment requires integration of all local
policies to compose a global access control policy for controlling information and resource.
Access control in such an environment is still an open problem. The much standardized
Role Based Access Control (RBAC) is yet to be fully utilized in a multi domain grid
environment like the Grids. Here, we present an architectural framework for adaptation
and implementation of RBAC for grid access control. Our approach includes solutions
for delegation and revocation in a single domain grid enterprise. The classical Role Based
Access Control, though an e
ective access control standard, does not address the issue
of resolving a local role into a global role. So, we also propose an architecture based
on RBAC, which can establish role equivalence among the domains by mapping a local
domain role to its equivalent global role.We use the approach of weighted ranking for the
same. The nal authorization decision is made based on the mapped global role ranking
and also the resource access policies.
