A new anonymous unlinkable mobile payment protocol

Abstract

Considering the development of mobile payment systems and feasibility and suitability of payment protocols we need to provide security requirements of users as well. In this paper we first introduce LMPP and MPCP protocols and show how these two protocols are unable to satisfy anonymity and unlinkability of merchant to issuer. Then we propose a lightweight mobile payment protocol that is based on LMPP protocol in which the mobile network operators are involved instead of financial institutions. To have a better performance in mobile networks, we employ symmetric key primitives in the proposed protocol. Moreover, our protocol provides anonymity and unlinkability of merchant to issuer as well as other main security requirements. © 2016 IEEE.
