Abstract:
There are many multi-party fair exchange protocols with applications in e-commerce transactions for buying digital products, buying physical products, digital signature of contracts, certified e-mail and non-repudiation. However, none of the existing multi-party fair exchange protocols can be applied to provide fair exchange in complex transactions where a customer buys digital products from different merchants while maintaining atomicity. In this paper, we propose a multi-party fair exchange e-commerce protocol for complex transactions in that the customer wants to buy several digital products from different merchants. Our protocol has applications to B2C/B2B scenarios. In addition to strong fairness, our protocol provides effectiveness, timeliness, non-repudiation and confidentiality.
