摘要
本文提出了一种基于散列链的微支付系统,它是一种离线的预支付系统,数字货币的可转移性,允许用户将未花费的数字货币转让给其它用户。同时,本方案是公平的,它使交易双方的利益都得到了很好的保护。与其它微支付方案(如PayWord)相比,由于本系统完全没有使用公开密钥算法,因而效率大大提高。此外,系统还为用户提供了有限的匿名性。
In this paper, we propose an off-line, prepaid micropayment system based on hash chain, which supports transferability of digital coins in a simpler way. Moreover, in our system, a hash chain remaining unspent can be transferred by one user to the other and the profits of both consumers and merchants are protected, so the fairness of our system is high. Compared with other micropayment schemes, e.g. PayWord, no public-key operation is required, which improves the efficiency of our system. In addition, restricted anonymity is provided in our system.
