Summary: We focus on techniques for proving behavioural equivalence between systems in DPI, a distributed version of the pi-calculus in which processes may migrate between dynamically created locations, and where resource access policies are implemented by means of capability types.
We devise a tractable collection of auxiliary proof methods, relying mainly on the use of bisimulations up-to $$\beta$$-reductions, which considerably relieve the burden of exhibiting witness bisimulations. Using such methods we model simple distributed protocols, such as crossing a firewall, a server and its clients, metaservers installing memory services, and address their correctness in a relatively simple manner.
For the entire collection see [Zbl 1089.68015].
