摘要Abstract: Electronic payment systems are increasingly in
need of improvement as they constitute the base for electronic
commerce which is rapidly dominating much trade and
particularly retail. One such system that allows payments of
low value is known as micropayment system the main
requirement for which is naturally ‘low cost of transaction’.
Payword is a micropayment system which uses hash chains
and achieves better computational performance. It is a creditbased
protocol involving a customer, vendor and broker.
However, in this system users have to generate a new payword
chain for each vendor from which they make a purchase and
also their payment process is not anonymous. MVPayword was
an extension to Payword which enables the user to make
purchases from different vendors using only one hash chain. In
this paper we shall introduce AMVPayword which is an
extension to MVPayword and provides anonymity for
customers. So users can be sure about the protection of their
privacy in payment system
