Programmable enforcement framework of information flow policies

We propose a programmable framework that can be easily instantiated to enforce a large variety of information flow properties. Our framework is based on the idea of secure multi-execution in which multiple instances of the controlled program are executed in parallel. The information flow property of choice can be obtained by simply implementing programs that control parallel executions. We present the architecture of the enforcement mechanism and its instantiations for non-interference (NI) (from Devriese and Piessens), non-deducibility (ND) (from Sutherland) and some properties proposed by Mantel, such as removal of inputs (RI) and deletion of inputs (DI), and demonstrate formally soundness and precision of enforcement for these properties.
