Secure Anonymous Donation Protocol

Donations are the main fund sources of election candidate, non-government organization, non-profit organization and charity etc. As the development of Internet, more and more donations are made online. At present, most online donations are made by smart card, and this kind donation is traceable. Anonymous donation may be necessary in some cases, but fully anonymous donation may be abused by the donee. The Anonymous donation system that can guarantee the anonymity of donor and can prevent donation abusing is appealing. Based on one-way hash function, we propose a system that the anonymity of donator can be guaranteed and the donation can be audited. This system may be of independent interest in other economic commerce applications.
