Mobile commerce is becoming more and more popular which makes it possible to purchase goods and services anywhere and anytime. However, traditional payment schemes do not suffice for our demand as more novel commercial services were provided. Therefore, it’s urgent to construct a safer and more convenient payment scheme for the forthcoming mobile era. A mobile payment scheme is proposed in the paper. The scheme called MPDTN provides an ideal mobile payment with dynamic transaction numbers. Through it, consumers can pay fares by using mobile phones no matter in real store or virtual shop. Besides explaining our payment architecture and processes in detail, evaluation of the MPDTN’s security from the aspect of defender and different roles of the attackers is provided in the paper. The investigation shows that, MPDTN can not only satisfy security criteria of confidence, integrity, authentication, and non-repudiation but also provide full transaction privacy to consumers.
