Verifiably Secure Process-Aware Information Systems (Dagstuhl Seminar 13341)

Authors: Rafael Accorsi, Jason Crampton, Michael Huth, and Stefanie Rinderle-Ma

Published in: Dagstuhl Reports, Volume 3, Issue 8 (2013)

Abstract
From August 18--23, 2013, the Dagstuhl Seminar "Verifiably Secure Process-aware Information Systems" was held in Schloss Dagstuhl -- Leibniz Center for Informatics. During this seminar, participants presented their current research and discussed open problems in the arising field of securing information systems driven by processes. The executive summary and abstracts of the talks given during the seminar are put together in this paper.

Verification and Refutation of Probabilistic Specifications via Games

Authors: Mark Kattenbelt and Michael Huth

Published in: LIPIcs, Volume 4, IARCS Annual Conference on Foundations of Software Technology and Theoretical Computer Science (2009)

Abstract
We develop an abstraction-based framework to check probabilistic specifications of Markov Decision Processes (MDPs) using the stochastic two-player game abstractions (\ie ``games'') developed by Kwiatkowska et al.\ as a foundation. We define an abstraction preorder for these game abstractions which enables us to identify many new game abstractions for each MDP --- ranging from compact and imprecise to complex and precise. This added ability to trade precision for efficiency is crucial for scalable software model checking, as precise abstractions are expensive to construct in practice. Furthermore, we develop a four-valued probabilistic computation tree logic (PCTL) semantics for game abstractions. Together, the preorder and PCTL semantics comprise a powerful verification and refutation framework for arbitrary PCTL properties of MDPs.
