Abstract

Mobile commerce (m-commerce) has undoubtedly become an omnipresent and an active area in electronic payments. It allows mobile user to buy and pay for things, pay his bill or make a bet via mobile phone when on move, anywhere and at anytime. However, several challenges in accountability and privacy properties have emerged with the widespread of mobile payments in recent years. Consequently, many public-key cryptography based mobile payment protocols have been proposed. However, limited capabilities of mobile devices (poor computation power, low battery capacity and limited storage memory), limitation of wireless networks (less bandwidth and reliability, and higher latencies), and higher wireless networks connection cost make these protocols unsuitable for mobile network. In this paper, a lightweight and private mobile payment protocol involving mobile network operators (MNOs) and employing symmetric key operations is proposed. It is unrealistic to expect all payers and all payees to have accounts with multiples MNOs. Therefore, the proposed protocol supports the interoperability among multiple MNOs, each with its own customer (payer) and merchant (payee), allowing customers of one MNO to make purchases from merchants of the other MNO. The symmetric cryptographic technique applied into the proposed protocol not only reduces the number of cryptographic operations and communication passes between the involved parties, but also achieves completely privacy protection of payer and satisfies all the criteria of end-to-end security property, party's requirements including non-repudiation. The proposed mobile payment protocol is analyzed with Kungpisdan et al. accountability logic (KP Logic). The result shows that the proposed protocol satisfies all security requirements in electronic payment transaction, enhances privacy protection and reduces the number of cryptographic operations in existing mobile payment protocols.
