Abstract:
We describe a typing system for a distributed ?-calculus which guarantees that
distributed agents cannot access the resources of a system without first being granted
the capability to do so. The language studied allows agents to move between distributed
locations and to augment their set of capabilities via communication with
other agents. The type system is based on the novel notion of a location type, which
describes the set of resources available to an agent at a location. Resources are
themselves equipped with capabilities, and thus an agent may be given permission
to send data along a channel at a particular location without being granted permission
to read data along the same channel. We also describe a tagged version of the
language, where the capabilities of agents are made explicit in the syntax. Using
this tagged language we define access violations as runtime errors and prove that
well-typed systems are incapable of such errors.
