Giuseppe Castagna , Jan Vitek, "Commitment and Confinement for the Seal Calculus", July, 1999


The Seal calculus is a distributed process calculus in which locations and movement of computational entities are explicit. The calculus is targeted at secure distributed appli-cations over large scale open networks such as the Internet. Security is addressed by a fine-grained access control mechanism. In [14] we motivated the design choices. Here we develop some technical tools, which include both a reduction and a commitment seman-tics and observational equivalences, to allow us to state and formally verify properties of mobile programs. In particular for studying security, we develop the notion of confine-ment. Confinement is essential for security; as it expresses that an execution environment has complete control over the communication capabilities of the programs that are running within it.
