Information Leakage Detection in Boundary Ambients1 1Partially supported by MIUR Projects "Interpretazione Astratta, Type Systems e Analisi Control-Flow" and "Modelli formali per la sicurezza", and the EU Contract IST-2001-32617 "Models and Types for Security in Mobile Distributed Systems"

Chiara Braghin, Agostino Cortesi, Riccardo Focardi
2003 Electronical Notes in Theoretical Computer Science  
A variant of Mobile Ambient Calculus is introduced, called Boundary Ambient, to model multilevel security policies.  ...  Ambients that may guarantee to properly protect their content are explicitly identified as boundaries: a boundary can be seen as a resource access manager for confidential data.  ...  Flow Direct Information Flow The concept of direct flow of high level/ambients outside security boundaries may be formalized as follows.  ...

Guardians for Ambient-Based Monitoring

G. Ferrari, E. Moggi, R. Pugliese
2002 Electronical Notes in Theoretical Computer Science  
Since the seminal work of Cardelli and Gordon, several ambient-based calculi have been proposed (Seal, Boxπ, Safe Ambients, Secure Safe Ambients, Boxed Ambients), mainly for supporting security.  ...  We exemplify the use of guardians for enforcing security properties.  ...  Acknowledgement The authors thank Cedric Fournet for helpful comments.  ...

2008 Information and Computation  
We then give a new notion of non-interference for Boundary Ambients aiming at capturing indirect flows, too.  ...  A variant of the Mobile Ambient calculus, called Boundary Ambients, is introduced, supporting the modelling of multilevel security policies.  ...  Direct information flow The flow of high-level ambients outside security boundaries is the downward flow that the Bell-LaPadula model intends to avoid. It may be formalised as follows.  ...
