A secure account-based mobile payment protocol

In this paper, we propose a secure account-based payment protocol which is suitable for wireless networks. The proposed protocol employs symmetric-key operations which require lower computation at all engaging parties than existing payment protocols. The proposed protocol also satisfies transaction security properties provided by public-key based payment protocols such as SET and iKP. The formal analysis illustrates that our protocol achieves the goals of payment protocols. Moreover, the credit-card information is not required to be sent during transactions which results in a security enhancement of the system.
