M3: Mobility types for mobile processes in mobile ambients

In CATS 2003, volume 78 of ENTCS, 2003


We present an ambient-like calculus in which the open capability is dropped, and a new form of ``lightweight process mobility is introduced. The calculus comes equipped with a type system which allows the kind of values exchanged in communications and the access and mobility properties of processes to be controlled. A type inference procedure determines the ``minimal requirements to accept a system or a component as well typed. This gives a kind of principal type. As an expressiviness test, we show that some of the most known calculi of concurrency and mobility can be encoded in our calculus in a natural way.
