We present a formal framework for incremental reasoning about authentication protocols, supported by the Protocol Derivation Assistant (Pda). A salient feature of our derivational approach is that proofs of properties of complex protocols are factored into simpler proofs of properties of their components, combined with proofs that the relevant refinement(More)
The specification of all aspects of a programming language requires adequate formal models and tool support. Montages specifications combine graphical and textual elements to yield language descriptions similar in structure, length, and complexity to those in common language manuals, but with a formal semantics. A broad range of people involved in(More)

A semi-visual framework for the speciication of syntax and semantics of imperative programming languages, called Montages, was proposed in an earlier work by the authors. The primary aim of this formalism is to assist in recording the decisions taken by the designer during the language design process. The associated tool Gem-Mex allows the designer to(More)
In the present paper, a methodology is presented which enables the implementation of the Action Notation formalism based on a formal and modular speciication. As a result, an interpreter and de-bugger is automatically generated which allows the visualization of an Action Notation program execution and the inspection of all semantic identities in terms of(More)
