Abstract: Mondex is a payment system that utilizes smart cards as electronic purses for financial transactions. The paper first reports on how the Mondex system can be modeled, specified and interactively verified using an equation-based method — the OTS/CafeOBJ method. Afterwards, the paper reports on, as a complementarity, a way of automatically falsifying the OTS/CafeOBJ specification of the Mondex system, and how the falsification can be used to facilitate the verification. Differently with related work, our work provides alternative ways of (1) modeling the Mondex system using an OTS (Observational Transition System), a kind of transition system, and (2) expressing and verifying (and falsifying) the desired security properties of the Mondex system directly in terms of invariants of the OTS.
