Mobile Online Banking Authentication Design And Implementation Based On Audio USBKEY

With the rapid development of mobile Internet and mobile intelligentterminal equipment, the technology of identity authentication of mobile banking has become diverse 。 We can realize identity authentication of mobile banking through the dynamic password card、token、SD card 、account password plus SMS verification code。Research and development of suitable authentication scheme in mobile banking security has become a major problem we face,because these authentication schemes has much potential safety hazard。Based on the research of the related technology of mobile banking authentication, I select a solution for mobile banking authentication audio communication audio based on USBKEY, and realizes the application of transaction in mobile banking, the main work and achievements are as following:1.This paper focuses on the communication protocol and interactive modebetween the intelligent mobile terminal and USBKEY, realizes the interactive communication between the two。2.Through the design of soft demodulation algorithm for security chip audio signal and automatically adjust the communication rate, the communication speed and compatibility of audio communication has been significantly improved。3.To meet the special requirements of mobile banking transaction security,I design a more security scheme of data transmission mobile intelligent terminal and audio USBKEY, with the studying of current mainstream security algorithm。4.Realize the mobile banking authentication in the use of C language and eventually pass the test in practical application。 Prove the function requirements of this terminal can complete the expected design goals。In this paper, through the research of mobile banking technology of identity authentication, using scientific research methods combining theory with practice, focus on implementation of the innovative design of audio communication soft demodulation algorithm, in practice through the test, the successful implementation of the predetermined design goals and design requirements。...
