| Summary: | 碩士 === 淡江大學 === 資訊工程學系 === 91 === Due to the advance of mobile network technologies, mobile personal devices are used to perform electronic payment. This paper proposes a new on-line payment scheme for mobile network. The proposed scheme is not only performed in the home domain, but also can be performed in visited domain. Our scheme provides consumer anonymity, authentication, non-repudiation and data integrity properties. The consumer can make transaction with shop, vendor machine and WAP site based on our scheme. Our scheme only includes symmetric encryption and one-way hash function, it takes lower computation cost and is more suitable for mobile device.
