The number of mobile commerce users is rapidly increasing because mobile commerce provides us with usability that can be able to pay for goods or services anytime, anywhere using mobile devices. To provide the secure mobile commerce, a number of security protocols have been proposed. Recently, An unlinkable anonymous payment scheme (UAPS) based on near field communication (NFC) is introduced. Unfortunately, we identified that UAPS had some drawbacks. First, it is vulnerable to DoS attacks. Seconds, it has symmetric key leakage problems. Third, its unnecessary account generation process causes computational inefficiency and user inconvenience. In this paper, we propose an enhanced un-linkable anonymous payment scheme based on NFC. In addition, to enhance the security and efficiency, we add transaction processes to our scheme because they were not described in UAPS. We show that our scheme is secure and suitable for mobile payment environments by analyzing and comparing it security.
