Mobile Payment System Using Dynamic Transaction Numbers

Abstract

With the developing of information technology, people nowadays can buy everything through the Internet conveniently. Also, handset devices are becoming more and more popular which makes it possible to purchase goods and services in the Internet anywhere and anytime. However, traditional payment schemes do not suffice for our needs as more novel commercial services were provided. Therefore, it’s urgent to construct a safer and more convenient payment scheme. This paper designs a mobile payment system in which the consumers purchase goods in the store or in the Internet by using cell phones and dynamic transaction numbers. Besides explaining our payment architecture and processes in detail, we evaluate the security of our scheme from aspects of users and attackers. As a result, our mobile payment system can not only satisfy security criteria of confidence, integrity, authentication, and non-repudiation but also provide full transaction privacy to consumers.
