In a distributed system, dynamically dividing execution between nodes is essential for service robustness. However, when all of the nodes cannot be equally trusted, and when some users are more honest than others, controlling where code may be executed and by whom resources may be consumed is a nontrivial problem. In this paper we describe a generic authorisation certificate architecture that allows...
Access control is an important building block in many distributed applications, and several solutions, both centralised and distributed, have been proposed and used for such applications. Certificates are particularly well suited to distributed systems and have been used in several ways.In this paper, we survey the certificate landscape from 2000 onwards. Our emphasis is on authorisation certificates...
