Embodiment
In order that the technical means, the inventive features, the objects and the advantages of the present invention are easy to understand, tie below
Conjunction is specifically illustrating, and the present invention is expanded on further.
The present invention can realize the enumerations information of the agreements such as UDK agreements, CCID and corresponding communication association first in firmware program
The handling process of view, response message and equipment are enumerated by the fixation in USB firmware program, being previously written different agreement
The response message of agreement.
In the enumeration request stage, PC can send out enumeration request order, and firmware decomposes request command, according to different requests,
Enumerations information fixed in advance, then it is returned to PC.
The information that PC can just return according to USB firmwares, corresponding handle is carried out to the USB device：If return to UDK fixation
Enumerations information, equipment are just identified as UDK equipment, if returning to CCID fixes enumerations information, equipment is just identified as CCID and set
It is standby.
Into after relevant device, entry communication stage, every kind of agreement does not have fixed form, according to the order of agreement,
Corresponding processing is done, returns to corresponding data.
Based on above-mentioned principle, concrete scheme of the invention is as follows：
Referring to Fig. 1, it show in this programme the realization principle schematic diagram of firmware in USBKEY.As seen from the figure, it is solid at this
The processing of two kinds of agreements of UDK communications protocol and CCID communications protocol and mutual switching are realized in part program.Whole process is divided into
Three phases：Before production, production when and production after the completion of.
Before manufacture, the complete process of two kinds of usb protocols is realized in firmware program：CCID enumerate terminal point information and
CCID passage processing, the UDK passage for enumerating terminal point information and UDK processing.
In the production phase, when agreement does not have before switching, USBKEY equipment acquiescence is UDK agreements, and firmware can only connect
The data that UDK end points is sent are received, so during USBKEY equipment first powers on, PC can send enumeration request information,
Firmware decomposes request command, and because USBKEY equipment acquiescence is UDK agreements, therefore firmware enumerates into single UDK agreements.PC ends phase
The port answered, which will identify that, carrys out the agreement, and PC ends will utilize special production port the Bind tool (i.e. the tool of production), pass through UDK
End points sends special prefab data (such as password or certificate) to the USBKEY of corresponding port；Firmware receives PC ends and sent
Data after, USBKEY COS systems will be called to carry out the read-write of data, after the completion of prefab data read-write, then write user
The special flag bit of communications protocol (i.e. corresponding FLASH certain bits), for representing the agreement to be switched to (i.e. next time
CCID protocol).
In the special flag bit of write-in user communication agreement, firmware program calls FLASH read/write function, is set in USB
Corresponding flag bit data are write on the address determined in standby built-in FLASH, if writing data 1, then the number on the address
According to being exactly 1；2 are write, data are exactly 2 on the address.Wherein, data 0：The equipment for representing single UDK；Data 1：Represent CCID
The equipment of agreement；Data 2：CCID+UDK equipment complex.
After the completion of production phase, after USBKEY is re-powered, USBKEY first detect whether be USB acquiescence operating protocol
(such as single UDK agreements)；If it is not, then detection flag bit, according to the flag bit of production write-in, is switched to the agreement of user job
(i.e. CCID protocol), USBKEY will enumerate into CCID protocol.Now, the USBKEY equipment is identified as CCID equipment by PC ends,
Communicated using CCID passages and USBKEY, according to receiving APDU orders, COS processing, the flow of return CCID data it is all and
Renew, now UDK passages just no longer receive prefab data.
The process is in specific implementation, and after writing flag bit in FLASH, USB device needs plug again, again on
After electricity, when PC sends respective request, according to the FLASH write before flag bit, the facility information after PC switchings is returned to
：
If 1, data are enumerated in CCID fixation and return to PC, the equipment that such PC just treats as USB device CCID.
If being cut into CCID protocol, fixed CCID protocol information is just returned to PC, equipment is just identified as CCID equipment naturally.Cause
Not return UDK facility information, USB device would not also be treated as UDK equipment by PC.
When realize USBKEY internal firmwares based on such scheme, it can either be carried out in the production phase using UDK agreements
Preset data operates, and so can effectively avoid using the different tools of production according to different agreements, cause tool of production kind
Class is various, bad the problem of safeguarding reduction efficiency；It can also can become needed for client in USBKEY service stages simultaneously
CCID communications protocol, normal user function is completed, so can effectively avoid USBKEY from constantly powering off in process of production
Again the problem of plug identification influences efficiency.
Except realizing CCID communications protocol, it can also equally realize that other communications protocol are fixed by such scheme, specifically
Realization principle and scheme it is same as described above, be not repeated here herein.
Referring to Fig. 2, it show such scheme in the specific implementation, the main working process figure of USBKEY firmwares.By scheming
Understand, whole process flow is as follows：
1st, USBKEY equipment carries out the initialization of related device first since principal function main () entrance,
2nd, the switching mark of usb protocol is read, is ready to enumerate processing.
The appropriate address data in FLASH are read first, the address is not write before manufacture, and it is acquiescence such as to read out
Value 0, expression are single UDK equipment, then PC first can send enumerations information request to end points is enumerated, after USB device receives,
The fixed data (such as figure left side) for there was only UDK information will be returned to PC, USB device has then just been treated as UDK equipment by PC.This
The identification of equipment just completes when individual.
3rd, accordingly, into while (1) major cycle process, the data of various applications are handled.
4th, what is received first is the interruption for enumerating end points, and after receiving enumeration request, firmware is read according in step (2)
Protocol switching indexed variable occurrence, do corresponding answer treatment：If the value of protocol switching indexed variable points to CCID associations
View, then return to CCID enumerations informations；If the value of protocol switching indexed variable points to UDK agreements, UDK enumerations informations are returned.
5th, USBKEY equipment enters read equipment during, according to the enumerations information of return, device enumeration into phase
The protocol devices answered：If enumerating into UDK agreement, equipment is received by UDK end points reads UDK protocol massages data, and from
Middle function decomposition into analytic function goes out APDU data, recalls COS systems and is handled, and response data is returned to by UDK passages again；
If enumerating into CCID agreement, equipment is received by CCID end points and reads CCID protocol message data, and therefrom
Function decomposition into analytic function goes out APDU data, recalls COS systems and is handled, and response data is returned to by CCID passages again.By
This completes the handling process of a data.
Relevant device is completed not into rear based on such scheme, you can enter the communication stage, PC is sent to UDK end points
UDK protocol data, after equipment receives, corresponding UDK agreements are handled, return to PC processing data.In processing most
Afterwards, if sending the special instruction of handoff protocol, after equipment receives, determination address that will be to FLASH, switching value, table are write
The secondary agreement switched under showing, for example 1 is write, next power-off is meant that, after reinserting, becomes CCID protocol.
Before powering off again, CCID protocol processes flow code can't perform, because current or single UDK association
View, after re-powering, workflow graph in execution, because protocol switching value has changed, then in device enumeration, equipment can judge
This value (the figure left side) will return to CCID fix information, so, equipment has reformed into setting for CCID if CCID value
Standby rather than UDK equipment.
From the foregoing, it will be observed that in production, only use and enumerate end points and UDK Path end points, CCID flow will not be gone to.
It has been produced that, after re-powering, switch to CCID, just only used and enumerate end points and CCID Path end points without using
UDK Path end points.
The general principle and principal character and advantages of the present invention of the present invention has been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the simply explanation described in above-described embodiment and specification is originally
