Step 103: the reader device bus driver is obtained reader device information;
Concrete, this step can comprise the steps:
(1) the inquiry request of reader device bus driver operation response system generates the inquiry instruction, and sends to card reader, obtains the device descriptor of equipment;
(2) in the device descriptor that returns of card reader with the type of single character representation deck, promptly comprise several characters in the device descriptor that card reader is returned and just represent this card reader to have several decks;
For example, the device descriptor that card reader is returned is A, represents that this card reader has only a deck, and the deck type is the A type; The device descriptor that card reader is returned is ABAC, represents that this card reader has four decks, and the type of No. 1 deck is the A type, and the type of No. 2 decks is a Type B, and the type of No. 3 decks is the A type, and the type of No. 4 decks is the C type.In the present embodiment, the device descriptor that returns with card reader is that CCS is an example, and promptly the card reader in the present embodiment has three decks, and the type of No. 1 deck is the C type, and the type of No. 2 decks is the C type, and the type of No. 3 decks is the S type.
Step 104: the reader device bus driver is according to reader device information creating physical device object;
After the reader device bus driver gets access to the device descriptor that card reader returns, according to deck type of representing in the device descriptor and deck number, create corresponding physical device object, corresponding with the deck of card reader respectively.
The device descriptor that returns with card reader is that CCS is an example, and the reader device bus is created 3 physical device object, and is corresponding respectively with 3 decks.
Step 105: the operating system of main frame is installed and is loaded intelligent card function for the physical device object of having created and drives, and each intelligent card function drives the smart card Driver Library of a standard of registration;
Wherein, operating system is that the function of the smart card device of the pairing deck installation of each physical device object respective type drives (being called for short intelligent card function drives), and each intelligent card function drives the smart card Driver Library of registering a standard.
In the present embodiment, the operating system installation of main frame has also loaded three intelligent card functions and has driven correspondingly with three decks in the card reader, is respectively the intelligent card function driving of C, C, S type.
Need to prove, the smart card Driver Library is used to provide the framework of a standard that the service controller of intelligent card function driving and smart card service is carried out alternately, in the middle of the embodiment of the invention, it is identical that three intelligent card functions drive pairing smart card Driver Library.
Need to prove that the smart card service can comprise service controller, explorer and database.Wherein, service controller be used to manage the smart card service, receive the request that drives from intelligent card function, management resource manager etc.; Explorer is used for adding new smart card device record or deleting existing smart card device record etc. at database.
Step 106: add new smart card device record in the smart card service in the middle of main frame;
Wherein, the smart card Driver Library that the smart card service drives and registers according to the intelligent card function that loads is created new smart card device record in the explorer of smart card service.In embodiments of the present invention, created three smart card device records in the explorer of smart card service, corresponding with three decks in the card reader respectively.So, three smart card devices just occurred in main frame, main frame can be operated each smart card device separately, sends or receive smart card operating instruction by reader device bus driver and smart card device.
By the end of step 106, multiple card-base card reader is identified as a plurality of card reader by main frame.
Introduce the condition monitoring process of blocking on each deck of the multiple card-base card reader that is identified as a plurality of smart card devices below:
Here need to prove that the state of each deck includes but not limited in the card reader: do not have card, have card not power on, power on.Wherein, after multiple card-base card reader was identified as a plurality of card reader by main frame, if the deck in the card reader does not have the IC-card sheet to insert, deck just was in no card state; If the IC-card sheet inserts deck, but main frame does not issue the instruction that powers on, or give the electricity instruction under the main frame, then deck is in not power-up state of card; If the IC-card card inserts deck, main frame issues the instruction that powers on, and after the smart card response also successfully returned ATR (Answer To Reset, reset answer), deck was in power-up state.
Step 107: the reader device bus driver sends interrupt request to card reader by interrupting transmission pipeline;
Need to prove, can communicate by two communication pipes between reader device bus driver and the card reader: bulk transfer pipeline and interruption transmission pipeline.
Wherein, the bulk transfer pipeline is used to carry out the transmission of data, as powers on, descends electricity instruction and other smart card operating instruction, and main frame and card reader are carried out data interaction according to the mode of answering of answering by the bulk transfer pipeline; Interrupt transmission pipeline, be used to transmit asynchronous event, as plug-in card, pull out card and card short circuit etc., card reader will send signal to main frame by the interruption transmission pipeline.
Wherein, in embodiments of the present invention, if do not have the insertion or the pull action of card in the card reader deck, then this interrupt request is suspended.
Step 108: the reader device bus driver receives the look-at-me that reader device is returned;
After having card to insert in the card reader deck, can send the look-at-me that card insertion is arranged to the reader device bus driver by interrupting transmission pipeline, be example still with 3 decks, concrete look-at-me can for:
No. 1 deck inserts card 0x5003
No. 2 deck inserts card 0x500c
No. 3 deck inserts card 0x5030
Accordingly, in the card reader use,, also can send the look-at-me that has card to extract to the reader device bus driver by interrupting transmission pipeline if when having card to extract in the card reader deck, concrete look-at-me can for:
No. 1 deck inserts card 0x5003
No. 2 deck inserts card 0x500c
No. 3 deck inserts card 0x5030
Step 109: the reader device bus driver is resolved the look-at-me that receives and interrupt type is passed to the corresponding intelligent card function and drives;
Wherein, the reader device bus driver is resolved the look-at-me that receives, obtain the interrupt type of this signal correspondence and smart card device, intelligent card function drives, upgrade the subset status list in the reader device bus driver, and by this subset status list the state variation situation of deck in the card reader is mapped to intelligent card function and drives.
Wherein, need to prove that the reader device bus driver can be set up a subset status list that is used for writing down card reader deck state after creating the smart card device success, include card and do not have the card two states.
For example, if what write down in the subset status list in the reader device bus driver is that No. 1 deck is no card state, the reader device bus driver receives look-at-me 0x5003, then the reader device bus driver is revised the Xiang Weiyou card state of No. 1 deck correspondence in its subset status list, simultaneously this state is mapped to intelligent card function and drives on 1.
Step 110: intelligent card function drives by the state variation of smart card Driver Library to smart card service report deck;
Concrete, the function that intelligent card function driving 1 provides by the smart card Driver Library
(SmartcardExtension-＞ReaderFunction[RDF_CARD_TRACKING]=RockeyCardTracking; ) revise in the smart card Driver Library 1 and represent that the parameter of intelligent card state is for there being card in the intelligent card state tracking I/O request package, and smart card deck status tracking I/O request package is sent to the service controller of smart card service, service controller is upwards made supporting movement to cut off enemy with report has card to insert smart card device, explorer has card with the status modifier of smart card device simultaneously, more the record in the new database.
Present embodiment provides a kind of recognition methods of multiple card-base card reader, pass through said method, multiple card-base card reader can be identified as a plurality of card reader by main frame, and main frame can be monitored the state variation of card in each " card reader ", make multiple card-base card reader can support to have in the card reader situation of the similar and different deck of a plurality of types, and for the shared communication bus of a plurality of decks in the multiple card-base card reader, a plurality of decks in the described multiple card-base card reader can replace, utilize to mutual exclusion and carry out data interaction between communication port and the main frame, the transmitting-receiving instruction is laid a good foundation.
It is a kind of based on the main frame of above-mentioned recognition methods and the communication means between the multiple card-base card reader that the embodiment of the invention also provides.Promptly in the reader device bus driver after upper strata application report card reader has card, upper layer application just can send instruction to specifying deck in the card reader by the reader device bus driver on demand, to smart card carry out as power on, PPS (Protocol and Pramateter Select, agreement and parameter are selected), operation such as read and write data.
Here need to prove that the service controller in the smart card service also is used to receive the application request from upper layer application, according to application request call function DeviceIOControl that receives and the concrete operation of indication in its parameter.
For example in function DeviceIOControl, the value representation action type of parameter d wIoCotrolCode, by the desired operation of smart card Driver Library analytical function DeviceIOControl, intelligent card function drives the result who parses according to the smart card Driver Library and generates the smart card operating instruction that meets the CCID agreement then.
Wherein, DeviceIOControl provides the parameter of calling also to comprise following parameter except that dwIoControlCode:
BOOL?DeviceIoControl(
HANDLE?hDevice， //handle?to?device
DWORD?dwIoControlCode， //operation
LPVOID?lpInBuffer， //input?data?buffer
DWORD?nInBufferSize， //size?of?input?data?buffer
LPVOID?lpOutBuffer， //output?data?buffer
DWORD?nOutBufferSize， //size?of?output?data?buffer
LPDWORD?lpBytesReturned， //byte?count
LPOVERLAPPED?lpOverlapped //overlapped?information
)；
The smart card Driver Library is used to provide the framework of a standard that the service controller of intelligent card function driving and smart card service is carried out alternately; After the smart card Driver Library is resolved DeviceIOControl, four functions below the intelligent card function driving is sent:
SmartcardExtension-＞ReaderFunction[RDF_CARD_POWER] ＝RockeyCardPower；
SmartcardExtension-＞ReaderFunction[RDF_TRANSMIT]＝RockeyTransmit；
SmartcardExtension-＞ReaderFunction[RDF_CARD_TRACKING] ＝RockeyCardTracking；
SmartcardExtension-＞ReaderFunction[RDF_SET_PROTOCOL] ＝RockeySetProtocol；
Intelligent card function drives according to these four functions and generates instruction, and the control smart card device carries out power-on and power-off, data transmission, tracking card state and operation such as agreement is set; Correspondingly, intelligent card function drive also be by above four functions to smart card Driver Library return message, the smart card Driver Library is reported to smart card service and upper layer application by DeviceIOControl then.
Referring to Fig. 2, this method comprises:
Step 201: the smart card operation request that intelligent card function drives according to upper layer application generates smart card operating instruction;
Wherein, upper layer application is specially the service managerZ-HU transmit operation request of serving to smart card to the operation of smart card, service managerZ-HU is according to the request call function DeviceIOControl of upper layer application, and the concrete operation of indication in function parameter, behind the smart card Driver Library analytical function, send function to the intelligent card function driving, intelligent card function drives the data encapsulation that will receive and generates the smart card operating instruction that meets the CCID protocol specification, and the 6th this intelligent card function of byte representation in this smart card operating instruction drives the numbering of pairing card reader deck.
For example, upper layer application produces the operation requests of getting random number to smart card device 1, intelligent card function drive 1 receive by function (SmartcardExtension-＞ReaderFunction[RDF_TRANSMIT]=RockeyTransmit; ) the data 0,x00 84 00 00 08 that imports into, intelligent card function drives 1 and uses 00 00 00 00 10 00 00 00 pairs of data that receive of an instruction 0x6f05 of CCID standard to encapsulate, and what obtain smart card operating instruction and be 0x6f 05 00 00 00 00 10 00 00 00 00 84 00 00 08 expressions is No. 1 deck;
Again for example, intelligent card function drives 2 according to the function that receives
(SmartcardExtension-＞ReaderFunction[RDF_CARD_POWER]=RockeyCardPower; ) in parameter judge No. 2 decks powered on or electricity operation down, can operation parameter 0x00 represent to power on, 0xFF represents electricity down, perhaps also can represent to power on, 0x55 represents down with parameter 0xaa; Judge will be to the operation that powers on of No. 2 decks if intelligent card function drives 2, then intelligent card function drives 2 and generates instruction: the 0x62 00 00 00 00 01 21 01 0000 that powers on that meets the CCID protocol specification, the instruction that powers on of No. 2 decks of expression, wherein the 6th byte 01 expression is No. 2 decks.
Correspondingly, intelligent card function drives the function below utilizing
(SmartcardExtension-＞ReaderFunction[RDF_CARD_TRACKING]=RockeyCardTracking; ) by smart card Driver Library notice smart card service generation card insertion or extract;
Moreover intelligent card function drives resolves the ATR information that the back card that powers on returns, the function below utilizing
(SmartcardExtension-＞ReaderFunction[RDF_SET_PROTOCOL]=RockeySetProtocol; ) communication pattern of serving current card by smart card Driver Library notice smart card follows t0 or t1 agreement.
Step 202: intelligent card function drives and by the reader device bus driver smart card operating instruction is sent to card reader;
Step 203: the card reader firmware program judges whether the hardware resource of current card reader is occupied;
If occupied, then execution in step 204;
If do not have occupiedly, then execution in step 205;
Wherein, need to prove, with 3 decks of the control of the chip timesharing in the present embodiment card reader is example, can only there be a deck to be connected with the reader device bus driver at synchronization by the bulk transfer pipeline, carry out data interaction, firmware program in the chip obtains the deck numbering of smart card operating instruction correspondence according to the card reader status command, come switching channel according to the deck number field in the smart card operating instruction, smart card operating instruction is sent to the deck of appointment and the current card reader hardware resource of monopolizing of modified logo information representation.
Wherein, identification information specifically refers to: use a bytes of storage space to preserve the occupied or idle identification information of expression card reader hardware resource in the register of card reader, revise 0xff when identification information being revised as 0x01, free time, perhaps represent that with 0x55 the card reader resource is occupied, 0xaa represents the free time as the card reader resource is occupied;
Also can use two bytes of storage space to preserve expression card reader hardware resource in the register of card reader is taken by a certain deck or idle identification information, taken by No. 2 decks as the card reader resource and then identification information to be revised as 0,x01 00, to be revised as 0,x00 10 when idle, wherein first byte data of identification information is represented the deck numbering, and second byte of identification information is used to represent that deck is occupied or idle.
Step 204: the card reader firmware program is hung up this smart card operating instruction, waits for that hardware resource is released, identification information is modified;
For example, current No. 1 deck state is for powering on, and what the reader device bus driver had issued No. 1 deck gets random number instruction 0x6f 05 00 00 00 00 10 00 00 00 00 84 00 00 08; Before the reader device bus driver receives this execution result of getting the random number instruction, No. 2 deck has inserted a card, then No. 2 deck states do not have card not power on by having to block to become, and card reader sends the signal 0x500c that No. 2 decks of expression have card to insert by interrupting transmission pipeline to the reader device bus driver; Upper layer application is learnt after No. 2 smart card devices have card to insert and is sent the request of powering on, intelligent card function drives 2 and receives the request back that powers on and generate No. 2 decks that meet the CCID agreement instruction 0,x62 00 00 00 00 01 21 01 00 00 that powers on, and send to card reader by the reader device bus driver, because the instruction of the random number of current No. 1 deck also is not finished, the card reader hardware resource is driven 1 by intelligent card function and takies, after the card reader firmware program judges that identification information knows that hardware resource is occupied, then with this operational order instruction suspends, wait for No. 1 deck execute get the random number instruction after, execution in step 205.
Step 205: card reader sends smart card operating instruction to the deck of appointment, and modified logo information;
Wherein, the card reader firmware program judges that current card reader status indicator information is for idle, deck during the instruction that the analysis of card reader firmware program receives obtains instructing, and instruction sent to deck in the instruction, this deck and reader device function are driven according to the mode of answering of answering carry out data interaction, instruction transmitting-receiving, revising card reader status indicator information simultaneously is that hardware resource is occupied.
Step 206: the smart card in the card reader deck is carried out the operational order that receives, and the link order execution result;
Wherein, smart card in the card reader deck is finished behind the operational order that receives, by the bulk transfer pipeline execution result that instructs is sent to the reader device bus driver, deck discharges the hardware resource of card reader, and the card reader of card reader firmware program modification simultaneously status indicator information is idle;
After the hardware resource of card reader was released, card reader status indicator information correction is the free time, next bar instruction of being hung up by the card reader firmware program was handed down to corresponding deck and modified logo information.
