Research on symmetric key-based mobile payment protocol security

摘要

This paper presents a payment model in which the mobile businessman is seen as trusted third party. Then we propose a new symmetric key-based mobile payment protocol and introduce both according key agreement protocol and payment protocol. In key agreement protocol, we introduce a Hash function with key based on RPC to guarantee payment authorization security. The payment protocol achieves security properties of payment anonymity, transaction privacy, incontestability and so on.
