Abstract
The access control problem in computer security is fundamentally concerned with the ability of system entitites to see, make use of, or alter various system resources. As such, many access control situations are essentially problems of concurrency. We give an account of fundamental situations in access-control in distributed systems using a resource-based process calculus and a hybrid of Hennessy-Milner and resource logic. This yields a consistent account of operational behaviour and logical reasoning for access control, that includes an analysis of co-signing, roles and chains-of-trust.
