We describe a monadic interface to low-level hardware features that is a suitable basis for building operating systems in Haskell. The interface includes primitives for controlling memory management hardware, user-mode process execution, and low-level device I/O. The interface enforces memory safety in nearly all circumstances. Its behavior is specified in(More)
— Existing noninterference frameworks for reasoning about system security assume a fixed configuration of domains governed by a security policy that does not change over time. A static security policy, however, cannot express the domain interactions present in many modern system designs, which allow users to configure the set of active domains at run-time.(More)
We introduce the Deductive Verification Framework (DVF), a language and a tool for verifying properties of transition systems. The language is procedural and the system transitions are a selected subset of procedures. The type system and built-in operations are consistent with SMT-LIB, as are the multisorted first-order logical formulas that may occur in(More)
— Separation kernels are the holy grail of secure systems , remaining elusive despite years of research into their design, implementation, and analysis. Though separation kernel research has achieved many successes, the disconnect between information flow theory and system implementation is a significant barrier to further progress. In this paper, we show(More)
Current practices for developing systems software usually rely on fairly low-level programming languages and tools. As an alternative, our group has been investigating the possibility of using a high-level functional language, Haskell, for kernel and device driver construction, with the hope that it will allow us to produce more reliable and secure(More)
58 3 Foreword The First International Workshop on MicroKernels for Embedded Systems was conceived to provide a forum for the discussion of issues in the application of microkernels in the embedded systems domain, including emerging problems, novel concepts, analysis approaches, and case studies. The workshop attracted submissions from both academia and(More)
