Sammanfattning

Static verification techniques can verify properties across all executions of a program, but powerful judgements are hard to achieve automatically. In contrast, runtime verification enjoys full automation, but cannot judge future and alternative runs. In this paper we present a novel approach in which data-centric and control-oriented properties may be stated in a single formalism, amenable to both static and dynamic verification techniques. We develop and formalise a specification notation, ppDATE, extending the control-flow property language used in the runtime verification tool Larva with pre/post-conditions and show how specifications written in this notation can be analysed both using the deductive theorem prover KeY and the runtime verification tool Larva. Verification is performed in two steps: KeY first partially proves the dataoriented part of the specification, simplifying the specification which is then passed on to Larva to check at runtime for the remaining parts of the specification including the control-centric aspects. We apply the approach to Mondex, an electronic purse application.
