Using Ambients to Control Resources
David Teller, Pascal Zimmer, and Daniel Hirschkoff

Current software and hardware systems, being parallel and reconfigurable, raise new safety and reliability problems, and the resolution of these problems requires new methods. Numerous proposals attempt at reducing the threat of bugs and preventing several kinds of attacks. In this paper, we develop an extension of the calculus of Mobile Ambients, named Controlled Ambients, that is suited for expressing such issues, specifically Denial of Service attacks. We present a type system for Controlled Ambients, which makes resource control possible in our setting.
