Secure Multi-Execution in Haskell
Paper in proceedings, 2011

Language-based information-flow security has emerged as a promising technology to guarantee confidentiality in on-line systems, where enforcement mechanisms are typically presented as run-time monitors, code transformations, or type-systems. Recently, an alternative technique, called secure multi-execution, has been proposed. The main idea behind this novel approach consists on running a program multiple times, once for each security level, using special rules for I/O operations. Compared to run-time monitors and type-systems, secure multi-execution does not require to inspect the full code of the application (only its I/O actions). In this paper, we propose the core of a library to provide non-interference through secure-multi execution. We present the code of the library as well as a running example for Haskell. To the best of our knowledge, this paper is the first work to consider secure-multi execution in a functional setting and provide this technology as a library.
