چکیده

A new algorithm is introduced for analysing possible nesting in Mobile Ambients calculus. It improves both time and space complexities of the technique proposed by Nielson and Seidl. The improvements are achieved by enhancing the data structure representations, and by reducing the computation to the Control Flow Analysis constraints that are effectively necessary to get to the least solution.

Nesting analysis of mobile ambients

A new algorithm is introduced for analyzing possible nestings in mobile ambient calculus. It improves both time and space complexities of the technique proposed by Nielson and Seidl. The improvements are achieved by enhancing the data structure representations, and by reducing the computation to the control 3ow analysis constraints that are e4ectively necessary to get to the least solution.

A Decentralized Implementation of Mobile Ambients

We present a graphical implementation for finite processes of the mobile ambients calculus. Our encoding uses unstructured (i.e., non hierarchical) graphs and it is sound and complete with respect to the structural congruence of the calculus (that is, two processes are equivalent iff they are mapped into isomorphic graphs). With respect to alternative proposals for the graphical implementation ...

PolyA: True Type Polymorphism for Mobile Ambients

Previous type systems for mobility calculi (the original Mobile Ambients, its variants and descendants, e.g., Boxed Ambients and Safe Ambients, and other related systems) offer little support for generic mobile agents. Previous systems either do not handle communication at all or globally assign fixed communication types to ambient names that do not change as an ambient moves around or interact...

Behind BANANA: Design and Implementation of a Tool for Nesting Analysis of Mobile Ambients

We present a survey of the work on control-flow analysis carried on by the Venice Team during the Mefisto project. We study security issues, in particular information leakage detection, in the context of the Mobile Ambient calculus. We describe BANANA, a Java-based tool for ambient nesting analysis, by focussing on analysis accuracy and algorithmic optimizations.

Boundary Inference for Enforcing Security Policies in Mobile Ambients

The notion of “boundary ambient” has been recently introduced to model multilevel security policies in the scenario of mobile systems, within pure Mobile Ambients calculus. Information flow is defined in terms of the possibility for a confidential ambient/data to move outside a security boundary, and boundary crossings can be captured through a suitable Control Flow Analysis. We show that this ...
