Title: | Team Semantics for the Specification and Verification of Hyperproperties | Authors: | Krebs, Andreas Meier, Arne VIRTEMA, Jonni Zimmermann, Martin |
Issue Date: | 2018 | Publisher: | Schloss Dagstuhl--Leibniz-Zentrum fuer Informatik | Source: | Potapov, Igor; Spirakis, Paul; Worrell, James (Ed.). 43rd International Symposium on Mathematical Foundations of Computer Science (MFCS 2018), Schloss Dagstuhl--Leibniz-Zentrum fuer Informatik,p. 10:1-10:16 (Art N° 10) | Series/Report: | Leibniz International Proceedings in Informatics (LIPIcs) | Series/Report no.: | 117 | Abstract: | We develop team semantics for Linear Temporal Logic (LTL) to express hyperproperties, which have recently been identified as a key concept in the verification of information flow properties. Conceptually, we consider an asynchronous and a synchronous variant of team semantics. We study basic properties of this new logic and classify the computational complexity of its satisfiability, path, and model checking problem. Further, we examine how extensions of these basic logics react on adding other atomic operators. Finally, we compare its expressivity to the one of HyperLTL, another recently introduced logic for hyperproperties. Our results show that LTL under team semantics is a viable alternative to HyperLTL, which complements the expressivity of HyperLTL and has partially better algorithmic properties. | Keywords: | LTL; Hyperproperties; Team Semantics; Model Checking; Satisfiability | Document URI: | http://hdl.handle.net/1942/27341 | ISBN: | 9783959770866 | DOI: | 10.4230/LIPIcs.MFCS.2018.10 | Rights: | © Andreas Krebs and Arne Meier and Jonni Virtema, and Martin Zimmermann; licensed under Creative Commons License CC-BY | Category: | C1 | Type: | Proceedings Paper |
