Abstract
In this work we use our proposed adaptation of the strand spaces method in the analysis of a fair exchange protocol for payment, proposed in [Zuo and Li 2005]. The protocol fails to provide timeliness and fairness to the buyer (Downloader), and four previously unreported attacks are traced regarding those properties. This is a continuation of the work started in [Piva et al. 2006].
