Certifiable Distributed Runtime Assurance

October 2017 Presentation
Dionisio de Niz

Presentation on research on the use of enforcers for runtime assurance in distributed systems


Software Engineering Institute



In this work, we are addressing those challenges in the context of distributed real-time systems (DRTS) by creating tools and techniques to

  • express enforceable policies in multiple domains, including logical and timing correctness
  • verify correctness of an enforcer implementation against its policy
  • combine multiple enforcers and resolve any inconsistencies between their behavior
  • verify that enforcers across multiple nodes of DRTS implement a global safety policy
  • deploy enforcers so that they cannot be circumvented by a well-defined attacker (e.g., one that has control of one/more monitored components)

We are validating our results on DoD-relevant examples.
