A New Third-party Payment Scheme with Anonymity for Mobile Commerce
Jen‐Ho Yang, Pei-Yu Lin · 網際網路技術學刊 · 2018
The traditional commercial transactions have been replaced by mobile transactions in recent years. To increase the security of the mobile transactions, various third-party mobile payment schemes have been proposed. However, we find that the related works have heavy computation and communication costs for mobile devices. In addition, the related schemes have a large number of keys to be maintained and managed by the user, and thus it causes the key management problem and increases the transaction loads for mobile devices. To solve the above-mentioned problems, we propose a new third-party mobile payment scheme for mobile commerce in this paper. In the proposed scheme, we adopt the concept of the trusted service manager (TSM) to be a trusted third party between the mobile user and the merchant. The TSM concept provides the anonymity and unlinkability for mobile users so the user’s payment privacy can be well protected. Besides, the computation and communication loads can be greatly reduced for the mobile devices. Therefore, the proposed scheme not only protects the mobile user’s payment privacy but also decreases the computation loads for mobile devices. Compared with the related works, the proposed scheme is securer and more efficient for the third-party mobile payment in practice.
