A calculus of trust and its application to PKI and identity management
We introduce a formal semantics based calculus of trust that explicitly represents trust and quantifies the risk associated with trust in public key infrastructure (PKI) and iden...

Timed Concurrent Game Structures
Abstract. We propose a new model for timed games, based on concurrent game structures (CGSs). Compared to the classical timed game automata of Asarin et al. [8], our timed CGSs are...
