Fair exchange is one of the most fundamental problems in secure distributed computation. Alice has something that Bob wants, and Bob has something that Alice wants. A fair exchang...
Fair exchange turns out to be an increasingly importanttopic due to the rapid growth of electronic commerce. An exchange is deemed to be fair if at the end of exchange, either each...
Recently, research has focused on enabling fair exchange between payment and electronically shipped items. The reason for this is the growing importance of Electronic Commerce and...
In this paper we propose an e-commerce protocol with the following features: (1) ensures true fair exchange, (2) does not require manual dispute resolution in case of unfair behavi...
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...
We formally specify a payment protocol described in [Vogt et al., 2001]. This protocol is intended for fair exchange of time-sensitive data. Here the µCRL language is used to form...
The fair exchange problem is key to trading electronic items in systems of mutually untrusted parties. In modern variants of such systems, each party is equipped with a security mo...
1 Electronic fair-exchange protocols have received significant attention from the research community in the recent past. In loose terms, the fair exchange problem is defined as at...
In recent years, existing computing schemes and paradigms have evolved towards more flexible, ad-hoc scalable frameworks. Nowadays, exchanging interactions between entities often ...
An electronic cash (e-cash) scheme lets a user withdraw money from a bank and then spend it anonymously. E-cash can be used only if it can be securely and fairly exchanged for ele...
