We present three case studies, investigating the use of probabilistic model checking to automatically analyse properties of probabilistic contract signing protocols. We use the pr...
In this paper, a practical electronic-payment (epayment) protocol is presented for use over the internet. The protocol applies the principle of true fair-exchange to the process o...
In PODC 2003, Park, Chong, Siegel and Ray [22] proposed an optimistic protocol for fair exchange, based on RSA signatures. We show that their protocol is totally breakable already...
