| Abstract: | One-way hash chains have been used in many micropayment schemes due to their simplicity and efficiency.this paper introduce the notion of multi-dimensional hash chains,which is a new generalization of traditional one-way hash chain.Based on multidimensional hash chains,this article propose two cash-like micropayment schemes,which have a number of advantages in terms of efficiency and security.it also point out some possible improvements to PayWord and similar schemes by using multi-dimensional hash chains,including Payword chains with multiple denomination,and a scheme that allows payment to multiple vendors using the same payword chain. |
