Abstract
Security-sensitive computerised communication systems are of increasing importance, however checking that they function correctly can be non-trivial. We propose automated verification techniques for the formal analysis of quantitative properties of such systems. Since communication networks typically require the collaboration of their participants to work effectively, we adopt a game-theoretic approach. Utility functions for each player, such as the degree of security offered
and the communication costs incurred, are formally specified using quantitative temporal logics. Then, building upon probabilistic verification techniques for parametric Markov chains, we develop methods to identify Nash equilibria representing stable strategies for the participants. We implement our methods as an extension of the PRISM model checker, and illustrate their applicability by studying anonymity-cost trade-offs in the Crowds anonymity protocol.
