Research On Security Protocol Of Mobile Payment

In recent years, with the high-speed development of mobile communication, and the rapid popularization of the mobile intelligent terminal equipments, e-commerce activities gradually enter into the era of mobile e-commerce; mobile payment usher in the period of rapid development and access to the rapid popularization and deployment in many countries.As a very important part in mobile, security protocol can ensure mobile payment’s safe operation and widely applications. Due to the resource constraints of wireless networks, we need light-weight and better mobile payment security protocols in the current study. The key work of this paper is how to design a light-weight and safe security protocol, the specific research results are as follows:(1) The security of SET, iKP and several other kinds of commonly used mobile payment security protocols are analyzed. The shortcomings of security protocol based on public key system have been pointed out;(2) An improved secure payment protocol based on symmetric key is proposed. A reduction in the number of the cryptographic operations has been obtained in the novel protocol. So it can provide a better effectiveness compared with the existing protocols. The security analysis shows that the new protocol has better security.
