A Theorem Proving Approach to Analysis of Secure Information Flow Authors: Adam Darvas and Reiner Hähnle and Dave Sands ---------------------------------------------------------- Most attempts at analysing secure information flow in programs are based on domain-specific logics. Though computationally feasible, these approaches suffer from the need for abstraction and the high cost of building dedicated tools for real programming languages. We recast the information flow problem in a general program logic rather than a problem-specific one. We investigate the feasibility of this approach by showing how a general purpose tool for software verification can be used to perform information flow analyses. We are able to handle phenomena like method calls, loops, and object types for the target language Java Card. We are also able to prove insecurity of programs.
