The Research Of SD Key Authentication System In Windows Phone Mobile

"With the rapid development of the mobile Internet and3G,4G network coverage improvement, and the convenience of smart phones,making more and more choose to use smart phones in the mobile Internet.This leads to a variety of network services was originally done on the PC side,but now they are done in the smartphone side,for example,e-commerce,e-government,banking,securities trading,online shopping,etc. This presents a serious problem:that is relative to the PC side, the phone side’s user authentication how to achieve.Currently there has a fairly complete authentication system on the PC side, for example, by means of PKI technology and USB Key hardware encryption technology can achieve the perfect user authentication on the PC side. But now in the mobile terminal authentication of users for just stay a simple way that making the phone number and password bound to pay,there are some security risks in such authentication.And with respect to use the hardware encryption to achieve the user’s authentication on the PC side,the mobile terminal has not yet fully mature hardware certification program.So this paper by means of the PC hardware encryption ideas,introducing SD Key hardware encryption program on Windows phone mobile platform,and by supporting of the wireless WPKI technology system,so will achieve the user’s identity authentication of high-strength in the mobile terminal.First,this paper analyzes the current development status of mobile payment which have a series of safety problems,on the basis of in-depth study of the Windows phone’s security system and the wireless WPKI technology system,combining the characteristics of wireless communication,propose to use SD Key hardware encryption solution to solve the problem of user authentication in the phone side.From the level of the entire phone’s SD Key system,this paper has a depth analysis and design for the internal software of SD Key and the phone side’s CSP layer and RIL layer.Finally,we make a application test for the system in HuaWei W2phone,verifying the feasibility of the system,and analyzing the security of the system.
