碩士 === 朝陽科技大學 === 網路與通訊研究所 === 92 === Network exchange is now widely used. However, it could not avoid confronting the problem of evolving from the network exchange. Some situations could be considered. For example, a buyer may not receive the order even if he/she makes the payment. For another example, the seller could get nothing even the merchandise was sent. We study presently the fair exchange proposed scheme for the design of efficient fair exchange protocols. We exploit the signature property to specify that two parties agree on the exchange each other. In our proposed scheme, we provided an exceptional mechanism without designing a complete exchange procedure. One party can dispute exchange results to the trusted third party (TTP) while the other interrupt or violate the procedure. TTP plays the role of resolving the dispute that makes two parties acquire exchange item each other. Furthermore, we take advantage of anonymity e-cash achievement to protect personal privacy.
