Initiating from the seminal work of Volpano and Smith, there has been ample evidence that type systems may be used to enforce confidentiality of programs through non-interference. However, most type systems operate on high-level languages and calculi, and “low-level languages have not received much attention in studies of secure information flow” (Sabelfeld and Myers, [16]). Further, security type systems for low-level languages should appropriately relate to their counterparts for high-level languages; however, we are not aware of any study of typepreserving compilers for type systems for information flow. In answer to these questions, we introduce a security type system for a low-level language featuring jumps and calls, and show that the type system enforces termination-insensitive non-interference. Then, we introduce a compiler from a high-level imperative programming language to our low-level language, and show that the compiler preserves security types.
