The Design And Study Of The Mobile Identity Authentication Service System In Nfc Mobile Payment

Mobile communication is become the tendency and hottest of technologies with the development of internet and electronic commerce. More and more people accept to consume and shopping by mobile device which is treated as convenient purchase device. However, with the development of the mobile communication, mobile device is facing with a big problem-security. How to ensure the user’s benefit and protect user’s private information is become the urgent topic.First, this thesis analyses the security problem in electronic commerce and introduction the technology of mobile identity authentication including the PKI technology and other. Point at the security problem of mobile identity authentication, this thesis design a authentication method combine with PKI technology and smart card technology to authenticate with uniform interface and support multiple services. In this system, this thesis is mainly used RSA encrypt and deciphering algorithm, and save user’s private key in use’s SIM card, save public key in server to accomplish the authentication of user identity and encrypt data when communication with user. This method can solve the security problem such as data ingrates and not denitrify, key save and generation, and communication with client. In client, only use the SIM card, it can save info including identity number, private key, and generation of keys.In this thesis, Firstly analyses the satiation of NFC mobile payment in foreign, and introduce the work principle of NFC technology, the compliment design of mobile payment system. After analyses the NFC mobile payment design, this thesis provides a system which supports NFC mobile identity authentication. Lastly, combination with the project of public bicycle renting system, it explains the concrete application in NFC mobile payment.
