Stochastic Games for Verification of Probabilistic Timed Automata
Probabilistic timed automata (PTAs) are used for formal modelling and verification of systems with probabilistic, nondeterministic and real-time behaviour. For non-probabilistic ti...

Providing both scale and security through a single core probabilistic protocol
Distributed systems are typically designed for scale and performance first, which makes it difficult to add security later without affecting the original properties. This paper ...
