However, the Mobile Ambients calculus and its variants are quite di#erent from Klaim, mainly because they assume an hierarchically organized net architecture where nodes (i.e. ambients) and the enclosed part of the net move as a whole, and because communication is restricted within ambients ....

....the propagation of access rights by ensuring that the permissions are in accordance with the local security policies. In this paper, to demonstrate the applicability of the approach we introduce a calculus of guardians. We choose as starting point of our investigation the Boxed Ambient (BA) [BCC01a,BCC01b]. This variant of the mobile ambients calculus [CG00b] drops the open capability and introduce fine grain mechanisms for ambient interactions (inspired by the Seal calculus [CV99] These changes provide better support for the specification of security policies. The calculus of guardians preserves ....
.... allow , choice and recursion ) The and combinator is not used in the examples. It could be used to compose guardians implementing elementary policies into more structured ones, as it is the case for passive composition of wrappers [FBF99] 4. 1 Firewall The firewall protocol (see [CG99,LS00,BCC01b]) has been introduced to examine which are the activities needed to control accesses through a firewall. In this protocol, ambient f describes a firewall and we assume that the name of the firewall must always remain unknown. An external agent a can enter the firewall f through a pilot ambient k, ....

....space : the local channel is private to the ambient, whereas the upward channel is available for access by clients. By relying on this interpretation, one can formalize a precise notion of resource access, namely: j # l 4X is a read access to whereas g( 4X is a write access. In [5] we showed that BA provides an effective framework for resource access security: specifically, we used a typed version of BA to model multilevel Mandatory Access Control (MAC) policies, including both military (no read up, no writedown) and commercial (no read up, no write up) security . Boxed ....

Boxed Ambients and Information Flow Security The type system we defined in [5] was targeted at resource access control, and specifically designed to protect resources, viz. channels, from undesired uses by unauthorized clients. Here, we change perspective, and focus on a different analysis that targets information flow. To motivate the change in perspective, consider the ....
