MCK: Model Checking the Logic of Knowledge

Artikel i vetenskaplig tidskrift, 2004

The specification formalism employed in model checking is usually some flavour of temporal or process algebraic language that expresses properties of the behavioural aspects of a system. Knowledge [5] is a modality that is orthogonal to the behavioural dimension, capturing properties of information flow. Logics of knowledge have been shown to be a useful framework for the analysis of distributed algorithms and security protocols, and model checking of these logics was first mooted by Halpern and Vardi [6]. Since that time theoretical aspects of model checking the logic of knowledge and its combinations with temporal logic have been studied [8–10]. The system MCK introduced in this paper implements parts of this theory.
