摘      要：Atomicity and anonymity are desirable properties for reliable and security e-Cash transaction and the guarantee of the participants’ interests. But there are conflicts between these two properties. In this paper, an atomic and anonymous e-Cash transaction protocol with off-line TTP (Trust Third Party) based on the extended CEMBS is presented. The novel protocol is analyzed for its atomicity and anonymity. The results of the analysis show that it not only provides atomicity and anonymity under unreliable communication and dishonest participants, but also features high efficiency and practicability. The new protocol also avoids transaction from an ambiguous state. Furthermore, it will be referenced often for the application of the atomic e-Cash transaction protocol.
