Research of Satisfying Atomic and Anonymous Electronic Commerce Protocol

Atomicity and anonymity are two important attributes for electronic commerce, especially in payment systems. Atomicity guarantees justice and coincidence for each participant. However traditional atomicity either bias to SELLER or CUSTOMER. Anonymity is also intractable, unanonymous or anonymity both leads to dissatisfying ending. Therefore, it is important to design a system in which satisfying atomicity and revocable anonymity are both enabled. In this paper, based on AFAP(Atomic and Fair Anonymous Protocol), we propose an approach to realize satisfying atomicity. In this method, not only SELLER’s satisfying atomicity but also CUSTOMER’s satisfying atomicity is supported. At the same time, based on Brands’ fair signature model, this method satisfies both anonymity and owner-trace or money-trace.
