For an efficient role based access control using attribute certificate in highly distributed computing environments, we use a technique of structuring role specification certificates. The roles are grouped and made them into the relation tree. It can reduce management cost and overhead incurred when changing the specification of the role. Further we use caching of frequently used role specification certificate for better performance in case applying the role. And for the global space reduction, we also consider the issue of tree normalization. In order to be scalable distribution of the role specification certificate, we use multicasting packets. In the experimental section, it is shown that our proposed method is secure and efficient.
