Types for Security in a Mobile World
Our society is increasingly moving towards richer forms of information exchange where mobility of processes and devices plays a prominent role. This tendency has prompted the academic community to study the security problems arising from such mobile environments, and in particular, the security policies regulating who can access the information in question. In this paper we propose a mechanisms for specifying access privileges based on a combination of the identity of the user seeking access, its credentials, and the location from which he seeks it, within a reconfigurable nested structure. We define BACIR, a boxed ambient calculus extended with a Distributed Role-Based Access Control mechanism where each ambient controls its own access policy. A process in BACIR is associated with an owner and a set of activated roles that grant permissions for mobility and communication. The calculus includes primitives to activate and deactivate roles. The behavior of these primitives is determine...
