| 摘 要： | 原子性对于可靠、安全的电子商务交易是必不可少的，是参与交易各方利益的重要保证．基于Mu等设计的高效e—cash方案，提出一种原子、有效e—cash交易协议．该协议将数字商品传输有机地整合到支付过程中，在去除强假设条件下(通信信道可靠和交易双方诚实)，协议不仅满足原子性、有效性，而且还为交易纠纷的解决提供非否认证据．

| Abstract: | Atomicity is necessary for reliable and secure electronic commerce transaction. An atomic and efficient e-cash transaction protocol based on e-cash scheme proposed by Mu, et al is presented. The delivery of goods is incorporated into payment in novel transaction protocol. The novel transaction protocol not only achieves the highest degree of atomicity under all circumstances (communication failure and participants dishonesty), but also meets high efficiency. Furthermore, the proposed protocol provides non-repudiation proofs for any future disputes. |
