Trust and partial typing in open systems of mobile agents
We present a partially typed semantics for Dpi, a distributed pi-calculus. The semantics is designed for mobile agents in open distributed systems in which some sites may harbor malicious intentions. Nonetheless, the semantics guarantees traditional type-safety properties at good locations by using a mixture of static and dynamic type-checking. We show how the semantics can be extended to allow trust between sites, improving performance and expressiveness without compromising type safety.
