Secure Lightweight mobile payment protocol using symmetric key techniques

The way people do the business and transactions are changing drastically with the advent of Information Technology. The customer wants to access information, goods and services any time and in any place on his mobile device. Receiving financial data, trade on stock exchanges, accessing balances, paying bills and transfer funds are done through mobile phones. Due to involvement of valuable financial and personal information, the mobile phones are vulnerable to numerous security threats. Most common activity in M-Commerce is the payment to the merchant using a mobile phone. Due to the constraints of wireless networks and security requirements of Mobile payment, there is a need for light weight and secure protocols. In this paper we present a secure mobile payment protocol which is suitable for m-commerce to transfer the payment from wireless networks based on symmetric key cryptography. Our protocol performs less number of cryptographic operations and satisfies more security requirements compared to existing standard payment protocols like SET, iKP etc.
