The growing importance of electronic commerce and the increasing number of applications in this area has lead research into studying methods of how to perform safe and secure online business transactions over the Internet. A central problem in this context is that of fair exchange, i.e., how to exchange two electronic items in a fair manner. We give a general introduction into the research area of fair exchange and discuss several formalizations of fairness. We find that, although a considerable number of fair exchange protocols exist, they usually have been defined for special scenarios and thus only work under particular assumptions. Furthermore, these protocols provide different degrees of fairness and cause different communication overhead. To alleviate this, we present a generalizing framework defining a suite of protocol modules which allows us to implement different fair exchange protocols. Depending on the properties of the exchanged items an appropriate fair exchange protocol can be selected and applied. Our study is accompanied by a comprehensive survey of the relevant literature.

“…A mobile agent of the host is a set of code and data which can execute the code with the data as parameter in some trusted processing environment (TPE). However, there are several issues related to security and trust while considering mobile agent-based electronic commerce [Pagnia et al 2000] [Wilhelm et al 1998] [Esparza et al 2003] such as nonrepudiation. We need to consider coordinations between Broker and TPE in our mobile payment systems to meet the commerce requirements of both efficiency and security.…”

Non-repudiation of a mobile payment transaction ensures that when a buyer (B) sends some messages to a seller (S), neither B nor S can deny having participated in this transaction. An evidence of a transaction is generated by wireless PKI (WPKI) mechanism such that B and S cannot repudiate sending and receiving the purchase order respectively. Broker generates a mobile agent for B which carries encrypted purchase order to S. A trusted third party (TTP) acts as a lightweight notary for evidence generations. One advantage of this agent-based non-repudiation protocol is to reduce inconvenience for mobile clients such as connection time and search for suitable merchant servers, etc.; it provides necessary security mechanisms for fair mobile payment transactions.

Non-repudiation of a mobile payment transaction ensures that when a buyer (B) sends some messages to a seller (S), neither B nor S can deny having participated in this transaction. An evidence of a transaction is generated by wireless PKI mechanism such that B and S cannot repudiate sending and receiving the purchase order respectively. The buyer generates a mobile agent which carries encrypted purchase order to the seller. This mobile agent is also issued a proxy certificate by the buyer; this certificate guarantees the binding relationship between them. One trusted third party acts as a lightweight notary for evidence generation. One advantage of this agent-based non-repudiation protocol is to reduce inconvenience for mobile clients such as connection time; it causes difficulty for fair transaction for mobile payments.
