An Efficient Decentralized Mobile Payment Protocol With Improved Security and Privacy

Mohammad Vahidalizadehdizaj, Pace University


The exponential growth of mobile devices makes them a suitable computing platform for electronic payment. However, there are serious challenges in e-commerce transactions, such as privacy protection, security, bandwidth limitations of mobile networks, and limited capabilities of mobile devices to handle excess or indirect computational time. The traditional e-commerce payment protocols that were originally designed to keep track of the traditional flows of data from desktop computers are vulnerable to attacks, and because they were not designed for mobile platforms, have excessive engineering overhead. In this thesis, a new private mobile payment protocol is introduced that is designed specifically for the mobile platform. It is based on a client-centric model that utilizes symmetric key operations. The protocol reduces the computational cost (the engineering overhead) of Diffie-Hellman key agreement protocol by using the algebra of logarithms instead of the algebra of exponents. The protocol achieves proper privacy protection for the payer by involving mobile network operators and generating temporary identities. It avoids replay attacks by using random time-stamp generated numbers.^
