A Novel Micropayment Scheme with Complete Anonymity

摘要：

The customers privacy may be exposed in most existing micropayment schemes. To protect the privacy of a customers identity, according to the definitions of anonymity given in this paper, a novel micropayment scheme (called xPay) with security, efficiency and complete anonymity is proposed. The scheme, based on hash chain, introduces both the debitbased payment mode and the pseudonym mechanism using prepaid cards, with the purpose of complete anonymity. In addition, in order to control the operation cost, a lower bound of the requesting coin quantity during one exchange, redemption or transfer procedure is specially set, and this setting is employed in the xPay scheme.
