Abstract

We use a distributed, enriched λ-calculus for describing networks of services. Both services and their clients can protect themselves, by imposing security constraints on each other's behaviour. Then, service interaction results in a call-by-property mechanism, that matches the client requests with service's. A static approach is also described, that determines how to compose services while guaranteeing that their execution is always secure, without resorting to any dynamic check.
