[Abstract]:With the rapid development of mobile Internet and mobile intelligent terminal devices, mobile network silver identity authentication technology has become diverse. Password card, dynamic token SD card and account password plus short message verification code can be used to realize the identity authentication of mobile network silver. These authentication schemes are faced with security problems, so it has become the most important problem for us to study and develop an identity authentication scheme suitable for mobile network silver security. Based on the research of mobile network silver identity authentication technology, this paper chooses a mobile network silver identity authentication solution based on audio USBKEY, and realizes its transaction application in mobile network silver. The main contents of the work and the results achieved are as follows: 1. This paper focuses on the design of communication protocol and interactive mode between mobile intelligent terminal and audio USBKEY, and realizes the interactive communication between them. Through the soft demodulation algorithm of audio signal and the scheme design of automatic adjusting communication rate, the communication rate and compatibility of audio communication are improved obviously. 3. Based on the current mainstream security algorithms, a more secure data transmission scheme of mobile intelligent terminal and audio USBKEY is designed to meet the special requirements of transaction security of mobile banking. Finally, the mobile network silver identity authentication is realized by C language, and the test results show that the terminal can fulfill the function requirement of the expected design target. Based on the research of mobile network silver identity authentication technology and the combination of scientific theory and concrete practice, this paper focuses on the innovative design of soft demodulation algorithm for audio communication, and passes the test in practice. The designed design goal and design requirement have been realized successfully.
