Boxed Ambients are a variant of Mobile Ambients that result from dropping the `open' capability, and introducing new primitives for ambient communication. The new model of communication is faithful to the principles of distribution and location-awareness of Mobile Ambients, and complements the constructs `in' and `out' mobility with finer-grained mechanisms for ambient interaction.

Abstract
Boxed Ambients are a variant of Mobile Ambients that result from dropping the `open' capability, and introducing new primitives for ambient communication. The new model of communication is faithful to the principles of distribution and location-awareness of Mobile Ambients, and complements the constructs `in' and `out' mobility with finer-grained mechanisms for ambient interaction. We introduce the new calculus, study the impact of the new mechanisms for communication o typing and mobility, and show that they yield an effective framework for resource protection and access control in distributed system
