A Mutual Authentication Enabled Fair-Exchange and Anonymous E-Payment Protocol

摘要

In this paper, a practical electronic-payment (epayment) protocol is presented for the purchase of digital products over the Internet. The proposed protocol realizes the true fair-exchange through a process of mutual authentication between the customer and the merchant, by which each party ensures that the item (product or payment) he/she is about to receive from the other party is valid and correct, whilst maintaining customer and merchant anonymity.
