Static analyses of object-oriented programs usually rely on intermediate representations that respect the original semantics while having a more uniform and basic syntax. Most of t...
This paper presents a calculus of channel security properties which allows to analyze and compare protocols for establishing secure in an insecure open network at a high level of a...
