Multi-Party Micro-Payment for Mobile Commerce

Abstract

This chapter introduces a new micro-payment scheme that is able to apply to multi-party for mobile commerce, which allows a mobile user to pay every party involved in providing services. The micro-payment, which refers to low-value financial transactions ranging from several cents to a few dollars, is an important technique in m-commerce. Our scheme is based on the hash function and without any additional communication and expensive public key cryptography in order to achieve good efficiency and low transaction costs. In the scheme, the mobile user releases an ongoing stream of low-valued micro-payment tokens into the network in exchange for the requested services. The scheme that is put forward satisfies the requirements for security, anonymity, efficiency and lightweight.
