....the properties and the model more precisely. A number of issues still remain to be investigated. We plan to investigate the security issues of the e commerce protocol using model checking. We need to investigate how the many different forms of electronic payment schemes that are available today [5, 17] can be incorporated into our protocol and the resulting solutions be verified for the existence of the properties. We also plan to improve our protocol by reducing the involvement of the trusted third party. ....

....each of these entities and the communication channels are prone to failures. We need to model these aspects in details and verify whether money atomicity holds or not in this scenario. We also need to investigate how the many different forms of electronic payment schemes that are available today [6, 20] can be incorporated into our protocol and the resulting solutions be verified for the existence of the properties. In future, we plan to improve upon the basic protocol. One such improvement involves reducing the involvement of the trusted third party. Not only is the performance of the trusted ....

....related to our work, but existing payment servers do not connect to the financial system for authorization or do not provide unforgeable realtime authorizations suitable for direct use by merchant servers. Existing network payment system proposals include the Simple Network Payment Protocol [7], CMU s Internet Billing Server [13] and ISI s NetCash [12] Though these payment servers do not require trust between the parties in a transaction, the parties must trust the payment server, and the payment server must be on line during the transaction. Kristol, Low, and Maxemchuk [11] propose a ....

To prevent such a risk, the bank has to keep track of either all the outstanding coins [MN93] or all the coins that have been previously spent [OO91] and check the list when verifying a transaction. Dukach in [D93] provides a technique for secure electronic payment over an open network like the Internet. However, SNPP (Simple Network Management Protocol) in [D93] does not provide anonymity. The rest of the paper is organized as follows. Section 2 describes the basic idea of the protocol, the cryptographic ....

Some systems propose symmetric cryptography for efficiency reasons (e.g. [9, 18, 15]) in particular, those that aim at micro payments. However, most proposals use public key cryptography in a way similar to one or the other iKP protocol. For example, 10] uses public key cryptography between merchant and gateway, and the protocol sketched in [7] appears cryptography quite ....

....banks rather than digital cash are that the currency cannot be lost, stolen, or forged. The disadvantage is that it requires real time communications to make a purchase. Many of the digital cash mechanisms can check for double spending after the purchase. The funds transfer approach is taken in [5] and [6] as well as in this paper. In the protocol in [5] a store knows the customer s bank and her bank account. The store and bank can collude to link the customer s identity and purchases. In order to associate a customer s identity and purchases in this anonymous credit card protocol, four ....

....cannot be compiled, as they routinely are in current systems. Complex communications protocols employing cryptographic building blocks are being developed not only to communicate, but also to protect privacy, e.g. in broadband networks [18, 17] in mobile networks [6] in electronic commerce [5, 13, 9], and in health insurance systems [12] We view a cryptographic protocol as a process by which information is transferred among some users and hidden from others. The collusion problem determines whether a subset of users can discover, through collusion, the information that is designed to be ....

Our approach avoids these problems since funds are transferred only among trusted entities. Reference [5] designs a protocol to perform payment transactions between mutually distrustful parties over an insecure network. It does not, as we do, focus on guaranteeing customers anonymity.
