多维Hash链及其在小额支付中的应用
Multi-Dimensional Hash Chains and Application to Micropayment Schemes
摘要：
单向哈希链由于其简单性和效率而被用于许多小额支付方案中。在本文中，我们引入了多维哈希链的概念，这是一个新的推广传统的单向哈希链。我们表明，这种结构具有存储计算复杂性的O（logN）每个链元素，这是在最近的文献中报道的最好的结果相媲美。基于多维哈希链，我们提出了两个类现金的小额支付方案，这两个方案在效率和安全性方面具有许多优势。我们还指出了通过使用多维哈希链对PayWord和类似方案的一些可能的改进
英文摘要：
One-way hash chains have been used in many micropayment schemes due to their simplicity and efficiency. In this paper we introduce the notion of multi-dimensional hash chains, which is a new generalization of traditional one-way hash chains. We show that this construction has storage-computational complexity of O(logN) per chain element, which is comparable with the best result reported in recent literature. Based on multi-dimensional hash chains, we then propose two cash-like micropayment schemes, which have a number of advantages in terms of efficiency and security. We also point out some possible improvements to PayWord and similar schemes by using multi-dimensional hash chains
