We present rendezvous-based access control for access control in the pre-hospital environment. Rendezvous-based access control is a simple cryptographic access control method that...
We propose role-based cascaded delegation, a model for delegation of authority in decentralized trust management systems. We show that role-based cascaded delegation combines the ...

This paper presents an approach that uses special purpose RBAC constraints to base certain access control decisions on context information. In our approach a context constraint is...
