Description
Technical field
The present invention relates to mobile payment intelligent card field, be specifically related to a kind of contactless read-write device based on SWPSE realization and method.
Background technology
Along with the fast development of mobile payment (allowing user to use its mobile terminal to carry out a kind of method of service of account payment to consumed commodity or service), utilizing NFC(NearFieldCommunication, near field communication (NFC)) application of mobile payment and use scenes be on the increase.At present, support that the mobile terminal of NFC all has three large characteristics: snap gauge simulation models, reader/writer mode and ad hoc mode.
Snap gauge simulation models is mainly by the CLF(ContactlessFront-end in mobile terminal, contactless front end) radio frequency front end chip and SE(SecurityElement, safe unit) come, SE supports the SIM card of SWP agreement (SingleWireProtocol, single-wire-protocol), the SD card supporting SWP agreement or flush bonding module.In mobile payment field, snap gauge simulation models finally allows mobile terminal become the contactless payment card of a standard.Because SE is used for mobile terminal, the client application therefore on mobile terminal can by access, and SE obtains the simple information on SE, and SE such as, pay relevant remaining sum, detail etc.
Reader/writer mode refers generally to the client application of mobile terminal directly by NFC protocol stack access CLF radio frequency front end chip, thus realizes read write line function.By the reader/writer mode of NFC, as long as NFC mobile terminal, read write line function (such as read label, read placard, read merchandise news, inquire about financial IC card remaining sum, financial IC card is supplemented with money) just can be realized in the air.
Ad hoc mode is mainly used to carry out exchanges data (such as transmitting the data files such as picture, business card, music), similar with reader/writer mode, and the client application of mobile terminal, by NFC protocol stack access CLF radio frequency front end chip, realizes the exchange of data.
In order to realize above-mentioned Three models, the client application of mobile terminal (being commonly referred to as NFC client application) is needed to participate in, due to mobile terminal operating system use time, easily be subject to the invasion of virus, therefore, there is certain risk when using in the NFC client application on mobile terminal operating system.
At present, when the client application of snap gauge simulation models uses, by a series of codes and standards formulated, constraint NFC client uses specific OpenMobileAPI(mobile terminal accessing interface) application corresponding with SE carry out exchanges data.But, the codes and standards not formulating standard is for the client application of reader/writer mode and the client application of ad hoc mode.In mobile payment field, pay class IC-card very high to the requirement of security, the payment read-write of IC card information, the transmission of instruction are all required to have safety guarantee, need to ensure correctness in transport process of data and instruction and integrality.Existing mobile terminal client terminal application (App) operation to CLF chip is open, in operational process PI virus or maliciously loaded wooden horse, also likely middle interaction data is monitored by trojan horse program, if therefore carry out Touchless manipulation to payment IC-card, then abnormally dangerous.
Traditional NFC mobile terminal realizes the method for contactless read-write device, is all to be controlled and access terminal NFC controller by terminal applies client, and terminal applies client controls and grasps all flow processs or operating process; Because terminal applies client is a common application on mobile terminal, therefore a lot of virus or wooden horse can intercept and capture the critical data of terminal applies client, and then the information of user of may leaking, and cause huge loss to user.
