Description
Technical field
The present invention relates to a kind of mobile payment testing apparatus and method, relate in particular to the device and method of the intelligent SD card test that realizes mobile payment.
Background technology
Mobile-phone payment is claimed in mobile payment again; Be one of focus of present emerging payment technology, its core concept is with closely contactless smart card and mobile phone terminal combine; Realize the on-site payment function through mobile phone simulated intelligence card, and utilize the network communication of mobile phone to realize the remote payment function; Simultaneously, utilize the high security of intelligent card chip to ensure the safety of payment information and payment process.That mobile-phone payment possesses is easy-to-use, safety and characteristic efficiently, is the development trend of following e-finance payment.
Aspect the mobile payment solution, China Unionpay, telecom operators and third party pay the industrial advantage that company all combines oneself and have released scheme and the product that meets self-growth.Wherein the intelligent SD card scheme of mobile operator SIM (Subscriber Identity Module) card has been selected not to be subject to by China Unionpay; And released the intelligent SD card of only supporting remote payment in 2010; Released the NFC-SD card of supporting remote payment and near field payment (Near Field Payment) simultaneously in 2011 again; And issued relevant technical standard and standard, just on market, widely popularize at present.
Intelligent SD card is meant the novel intelligent SD card that forms afterwards at the inner safety intelligent card chip (SE) that embeds the finance level of traditional SD card, and its framework is as shown in Figure 1; It as long as make that most mobile phones has the function that SD card slot just possesses mobile-phone payment on the market, thereby is beneficial to the professional expansion of mobile-phone payment under the prerequisite that does not change the hardware designs of mobile phone own.Intelligent SD card is divided into two kinds, and a kind of is the SD card of not supporting single-wire-protocol (SWP, Single Wire Protocol) interface, and this SD card can be used on the intelligent terminal of any band SD draw-in groove, but it only supports the remote payment function, can't support the on-site payment function; Another kind is a SD card of supporting the SWP interface; Be called NFC-SD card or SWP-SD card; This SD card can be used on the intelligent terminal of specific support close range wireless communication (NFC, Near Field Communication) function, can support remote payment and on-site payment function.
At present; Similarly protocol conversion device only limits to the conversion of physical aspect aspect; Convert Plug-in lesser calorie (like the SIM that uses in the regular handset) or 3FF lesser calorie (like the SIM of the smaller szie that uses on the iphone mobile phone) into like the kilocalorie (such as mass transit card, interchanger etc.) of ID-1 standard; This kind equipment is the adaptive conversion of interface form, and connecting line adopts direct-connected mode, does not carry out the conversion of software protocol aspect and adaptive.
Have again; It with the Unionpay long-range financial intelligent SD card (abbreviation NFC-SD card or the SWP-SD card) product with on-the-spot mobile payment service of the support promoted of main body; This product has been expanded two pin PIN9 that are exclusively used in the near field payment interface on the original standard pin of SD card basis; PIN10, as shown in Figure 1; Wherein, PIN9 is the SWP interface, is used for that (the SWP interface of (being non-contact front-end, Contact-Less Front-end) chip links to each other with NFC portable terminal CLF; PIN10 then is used to connect power supply, is used to the chip operation power supply on the intelligent SD card.Because PIN9 is directly to be connected with intelligent card chip (Smart IC) in SD card inside with PIN10, and without the processing that blocks the SD controller, so can't carry out the conversion of protocol level and adaptive.So the needs of some producer in order to test; Be connected to three lines of the PIN9 of SD card, PIN10 and GND (ground wire) on the C6, C1, C5 interface of SIM; This conversion equipment also is to adopt the direct-connected mode of connecting line; Do not carry out the conversion of protocol level and adaptive yet, only can be used in the adaptive test of SWP interface, can not carry out communication with the ISO7816 interface of smart card in the SD card.The characteristics of above interface conversion equipment are, just carry out the interface conversion of physical aspect, and circuit-line adopts direct-connected mode, does not carry out the conversion of software protocol aspect, does not also have the participation of main control chip, so, all there is certain limitation.
This shows that existing intelligent SD card converts the interfacing equipment of SIM into, only can realize the conversion of SWP interface; And be the interface conversion of physical aspect; Circuit-line adopts direct-connected mode, does not carry out the conversion of software protocol aspect, does not also have the participation of main control chip.So, can't the adaptive existing testing apparatus that possesses the SIM interface to the intelligent SD card product of present popularization, like TC3 equipment, can not be used on the NFC mobile phone of only supporting SWP SIM scheme and test.Therefore; Need to propose a kind of device and method of realizing the intelligent SD card test of mobile payment; Can be through the intelligent SD card interface conversion being become the interface of SIM from the hardware and software protocol level, and with mobile phone or testing apparatus with SIM interface intelligent SD card each item function is tested easily.

After the SD controller monitoring has write operation to the said application interface file of memory block in the said intelligent SD card, after reading the content that writes and resolving to said Application Protocol Data Unit order, be transmitted to safety intelligent card chip processing in the said intelligent SD card; The response data that said safety intelligent card chip is carried out after the said Application Protocol Data Unit instruction is given said SD controller, is written back in the said application interface file by the response data of said SD controller with said order;
Said main control module reads the content of said application interface file, if judge the file content that reads renewal is arranged, and then the said file content that reads is stored in the output buffers of said SD host mode interface; If the file content that reads does not upgrade, then postpone a period of time continued and read, till reading meaningful renewal or reading above maximum latency;
Said main control module parses the response data of said order from the file content that said output buffers reads by said SD host mode interface format; And after this response data carried out completeness check, export said testing apparatus through the hardware driving interface according to the call format of ISO7816 slave mode interface.
10. according to the described method of claim 9, it is characterized in that, also comprise:
Said testing apparatus receives that said safety intelligent card chip carries out the response data of said order and handle; All accomplish if judge test event, then write down, show and analyze the result of whole test events, otherwise send next bar test command, proceed the test of next test event to tested intelligent SD card.
