摘要: 由于hash函数的高效安全性,利用hash链构造微支付方案已经成为一个研究热点。在WCC’2005会议上,Quan Son Nguyen提出了基于RSA的多维hash链模型。该文指出了该方案的不可行之处,并对该方案进行了改进,使之满足PayWord的要求。

Abstract: Micropayment schemes based on hash chain have been developed in recent years for hash function’s efficiency. Quan Son Nguyen proposed n-dimensional hash chain structure in WCC’2005. This paper analyses it is impractical, and modifies it to apply to Rivest’s payword scheme.
