For an efficient role based access control using attribute certificate in highly distributed computing environments, we use a technique of structuring role specification certificat...
The RBAC96 access control model has been the basis for extensive work on role-based constraint specification and role-based delegation. However, these practical extensions can als...
Patterns are useful knowledge about recurring problems and solutions. Detecting a security problem using patterns in requirements models may lead to its early solution. In order t...
