Probabilistic model BIO COENZYMATED METHYLFOLATE checkers like PRISM only check probabilistic systems of a fixed size.To guarantee the desired properties for an arbitrary size, mathematical analysis is necessary.We show for two case studies how this can be done in the interactive proof assistant Isabelle/HOL.The first case Figure Skating - Skates - Boys study is a detailed description of how we verified properties of the ZeroConf protocol, a decentral address allocation protocol.
The second case study shows the more involved verification of anonymity properties of the Crowds protocol, an anonymizing protocol.
