Title:  Software Trustworthiness
Research & Technical Areas:  Information Systems

  Objective:  Develop tools which provide a measure of the risks inherent in the system, ie. provide the level of software trustworthiness.
  Description:  The Air Force is becoming ever more dependent on the reliable, secure, and accurate operation and interaction of software. Tools which provide an empirical software engineering evaluation/development processes are needed. In particular, this topic is looking for tools which will provide an objective measure of the risks inherent in a system due to the software composition of the system. Such a tool might provide the Air Force a measure that the operational system is: 1. Hacker-proof and free of embedded trojan-horses, an issue as more software is developed via out-source methods. 2. Robust in the face of interaction with multiple software applications. The Air Force needs to have confidence that a fault in one piece of software does not introduce spurious, unintended paths in a set of integrated software components. 3. Verifiable, given the often sparse level of software specification accessability. 4. Trustworthy from a whole-system perspective, integration of trusted components does not necessarily yield a trusted system.

  PHASE I: Survey industry and technology roadmaps, determine feasibility, develop preliminary design, estimate costs and develop a program plan.
  PHASE II: Build and test computational prototype.

  DUAL USE COMMERCIALIZATION: Military application: The work developed under this effort will potentially be useful in many types of military combat and mission support information systems. Commercial application: The concept will potentially also be useful for non-military applications in communications and software development as well.
