摘要: In this paper, we extend the Pay-Word micro-payment scheme using the 1- dimension one-way hash chain to generate an n-dimension one-way hash chain.
According to the system requirements, a user can flexibly choose the number of dimensions to gain the best time/space trade off. The proposed scheme is based on an n-dimension one-way hash chain, which can improve the efficiency of deriving the pay-words but also increase the temporary storage space. In addition, this scheme is fit for real-time payment.
