Resumen de A uniform type structure for secure information flow
The p-calculus, a calculus of mobile processes, can compositionally represent dynamics of major programming constructs by decomposing them into name passing. The present work reports our experience in using a linear/affine typed p-calculus for the analysis and development of type-based analyses for programming languages, focussing on secure information flow analysis. After presenting a basic typed calculus for secrecy, we demonstrate its usage by a sound embedding of the dependency core calculus (DCC) and the development of the call-by-value version of DCC. The secrecy analysis is then extended to stateful computation, for which we develop a novel type discipline for imperative programming language that extends a secure multi-threaded imperative language by Smith and Volpano with general references and higher-order procedures. In each analysis, the embedding gives a simple proof of noninterference.
