Description
Technical field
The present invention relates to communication technical field, relate in particular to implementation method and device that a kind of noncontact is swiped the card and used.
Background technology
Along with the swipe the card development of technology of noncontact, the noncontact mode of swiping the card has possessed more and more swipe the card performances of mode of contact that are better than, for example, noncontact is swiped the card in the mode, machinery-free contacts between non-contact card and the card-reading terminal, avoid the various faults that produce owing to the Mechanical Contact card-reading terminal, as avoided in mode is swiped the card in contact entering owing to roughly plug-in card, the insertion of non-card foreign object, dust or greasy dirt the Card Reader failure that the loose contact factor such as plug-in card zone causes.In addition, non-contact card is compared with contact card, and the problems such as module comes off, electrostatic breakdown, crooked damage have been avoided without exposed module in the surface, and the dependability of card is higher.Therefore, non-contact card relies on its good performance and higher cost performance to be widely applied, and has been widely used at present the every field such as public transport, medical treatment, all-in-one campus card, gate inhibition.
In order to utilize better the noncontact technology of swiping the card, the technology of noncontact having been swiped the card at present merges with the portable terminal that application is popularized very much, this portable terminal that possesses the noncontact function of swiping card is NFC (Near Field Communication, close range wireless communication) terminal, the NFC terminal is combined the noncontact technology of swiping the card by built-in aerial and security module with portable terminal, for the user provides good use impression, wherein, security module can be SIM (Subscriber Identity Module client identification module) card, SD (Secure Digital Memory Card, safe digital card), SE (Secure, safety) module etc. independently.
The NFC terminal can have three kinds of mode of operations, be respectively: snap gauge simulation models, card reader pattern and ad hoc mode, the implementation of at present typical NFC terminal is divided into two classes: a class is CLF (Contactless Fronted, non-contact front-end) module links to each other with single security module, and the another kind of CLF of being module links to each other with built-in each security module of terminal simultaneously.Fig. 1 shows the structural representation that the CLF module links to each other with single security module, and as shown in Figure 1, the CLF module in the NFC terminal only is connected with a security module, and this security module can be SIM card, SD or SE module etc. independently.Fig. 2 shows the structural representation that the CLF module links to each other with built-in each security module of terminal simultaneously, and as shown in Figure 2, the built-in security modules such as SIM card, SD and SE module of the CLF module while in the NFC terminal and NFC terminal are connected.
In CLF module shown in Figure 1 and the connected mode of security module, CLF module only fixing and single security module links to each other, there is so the unmatched situation of security module that the NFC terminal is introduced new security module or the security module that links to each other with the CLF module and the application of swiping the card are supported, thereby causes the noncontact of NFC terminal to swipe the card unsuccessfully.For example, the CLF module in the NFC terminal only is connected with the SE module, if insert SIM card in this NFC terminal, then the non-contact application on this SIM card can't be used.In CLF module shown in Figure 2 and the connected mode of security module, although the CLF module in the NFC terminal can be simultaneously and the SE module, a plurality of security modules that the NFC terminals such as SIM card are supported link to each other, but in actual applications, the NFC terminal can only support the CLF module to communicate with a security module in each security module that is connected, the interface channel that is about between the security module in CLF module and each security module that is connected is set to state of activation, all the other interface channels are set to dormant state, the interface channel that only is in state of activation could normally use, there is so equally the new security module of NFC terminal introducing or is set to the security module that links to each other with the CLF module of state of activation and the unmatched situation of security module of the application support of swiping the card, thereby cause the noncontact of NFC terminal to swipe the card unsuccessfully.For example, CLF module in the NFC terminal is connected with SE module and SIM card, the interface channel of CLF module and SE module is set to state of activation, the interface channel of CLF module and SIM card is set to dormant state, then when the security module of non-contact application support is SIM card, then this application can't be used.

Table 1
| Application identities | The security module sign |
| 0xD1560001018003800000000100000001 | SE |
| 0xD1560001018003800000000100000002 | SIM |
| 0xD1560001018003800000000200000003 | SD |
The corresponding relation that the application identities of preserving according to upper table 1 and security module identify, application identities is the corresponding security module SE of the application of " 0xD1560001018003800000000100000001 ", application identities is the corresponding security module SIM of the application of " 0xD1560001018003800000000100000002 ", and application identities is the corresponding security module SD of the application of " 0xD1560001018003800000000100000003 ".
The embodiment of the invention one further provides Fig. 1 specific implementation process of the step 103 that corresponding flow process comprises, being the CLF module is sent to the detailed process that the security module corresponding with the security module sign of determining processed with the noncontact that the receives order of swiping the card, and this process comprises:
That determines in step 102 swipes the card security module corresponding to the application identities of carrying in the order when being designated one with this noncontact, and the order of then directly this noncontact being swiped the card is sent to security module corresponding to security module sign of determining and processes;
That determines in step 102 is designated two when above with this noncontact security module corresponding to the application identities of carrying in the order of swiping the card, and the order of then this noncontact being swiped the card is sent to the highest security module corresponding to security module sign of security module sign medium priority of determining and processes.Wherein, the priority of security module sign can be specified by the provider that uses in advance, also can be specified by the user, the precedence information of this security module sign can be preserved in the lump with the corresponding relation of security module sign and application identities, for example, the security module sign of corresponding limit priority is set to default, when the corresponding a plurality of security module sign of same application identities, selection is set to security module corresponding to default security module sign for processing the security module sign of application corresponding to this application identities, generally speaking, only have one to be set to defaultly in a plurality of security modules sign corresponding to same application identities, and the application identities on the same security module does not allow repetition.For example, electronic wallet application (application AID is 0xD1560001018003800000000100000000) is preset on SE and the SIM card, and wherein the electronic wallet application on the SE is default application, shown in the table 2 specific as follows:

| 0xD1560001018003800000000100000000 | SIM card | No |
Corresponding relation according to upper table 1 preservation, application identities is that the electronic wallet application of " 0xD1560001018003800000000100000000 " can be simultaneously in security module SE and security module SIM card, but only be set to default at security module SE, therefore, swiping the card during order of this electronic wallet application arranged during subsequent applications, this order can be routed to SE and process, unless the interface channel between CLF module and the SE is closed.
In above-mentioned flow process corresponding to Fig. 1 that the embodiment of the invention one provides, if definite result of above-mentioned steps 102 is: the CLF module is not determined and this noncontact security module sign corresponding to the application identities of carrying in the order of swiping the card according to the corresponding relation of preserving, the use success ratio of then swiping the card in order to improve noncontact, the CLF module can be further determines to process the swipe the card security module of order of this noncontact by the mode of broadcasting, this process mainly comprises the steps: specifically as shown in Figure 4
In this step 401, the CLF module can send this noncontact order of swiping the card to connected all security modules, and purpose is to determine to swipe the card to this uses the security module of processing.
In this step 402, security module is after order is swiped the card in the noncontact that receives the transmission of CLF module, obtain swipe the card application identities in the order of this noncontact, if security module is determined the application of self supporting that this application identities is corresponding, then be used for the information that sign is supported this application to CLF module feedback, if do not support, then need not feedback.Wherein, the form of the information of the application that is used for this application identities of sign support that security module sends can pre-determine, for example, in order to reduce transinformation, can establish the set representative supports, " 0 " representative is not supported, can determine flexibly this information format in the practical application, enumerates no longer one by one herein.
In this step 403, be a plurality of if fed back the security module that is used for the sign application identities that order carries of supporting to swipe the card this noncontact, then the CLF module can go out security module according to predefined rules selection this noncontact order of swiping the card is processed.
So far, determine processing the swipe the card flow process of security module of order of this noncontact by the mode of broadcasting finishes.
By flow process corresponding to Fig. 4, even the corresponding relation of preserving according to the CLF module is not determined and this noncontact security module sign corresponding to the application identities of carrying in the order of swiping the card, the CLF module also can be determined by broadcast mode can be to this noncontact security module that order processes of swiping the card, thereby has guaranteed the use success ratio that noncontact is swiped the card and used.
Further, if the corresponding relation of preserving according to the CLF module is not determined and this noncontact security module sign corresponding to the application identities of carrying in the order of swiping the card, illustrate that then the CLF module do not preserve the corresponding relation of this application identities and security module sign, in the case, the CLF module can be further according to this broadcasting determine can be to swipe the card definite result of the security module that order processes of this noncontact, the application identities of preservation and the corresponding relation of security module sign are upgraded, particularly, after above-mentioned steps 402, namely after the CLF module receives the information that is used for application corresponding to application identities that sign supports to swipe the card this noncontact order carries of security module feedback, the CLF module can be preserved respectively the swipe the card corresponding relation of the described application identities of carrying in the order of the security module sign of having fed back the security module that is used for the sign application identities that order carries of supporting to swipe the card this noncontact and this noncontact, thereby follow-up when having the noncontact that comprises this application identities to swipe the card order, can be directly determine this noncontact security module that order processes of swiping the card according to the corresponding relation of preserving, thereby improve the efficient of swiping the card.
The noncontact that the embodiment of the invention one provides is swiped the card in the implementation method of using, and in order to improve the control to the NFC terminal, can also control the connection status of CLF module and each security module in the NFC terminal.Fig. 5 shows the synoptic diagram of CLF module and security module connection status in this NFC terminal, as shown in Figure 5, this CLF module comprises controller, and this controller is used for receiving security module the control CLF module that sends and the order of setting security module interface channel closure or openness that safety equipment comprise.In the practical application, on the interface channel of CLF module and each security module switch can be set, if when controller receives control CLF module and sets the order of security module interface channel unlatching, can close this switch, this moment, this interface channel was effective, can communicate; If when control CLF module is closed with setting security module interface channel, can open this switch, this moment, this interface channel was invalid, can't communicate.Be to be understood that, mode take switch control CLF module and the interface channel of security module described herein in the practical application, can have multiple control modes only as realization a kind of implementation of the present invention, as significance bit of interface channel etc. is set, enumerate no longer one by one herein.And, in the practical application, the equipment that safety equipment shown in Figure 5 can used provider or NFC terminal operator and provide, namely these safety equipment are independent of the NFC terminal, being used for application provider or NFC terminal operator manages application, these safety equipment also can be built in the NFC terminal inner, by user control, so that the user manages control to self NFC terminal.
Fig. 6 shows interface channel state that the CLF module preserve to be used for identifying described CLF module and security module and is the schematic flow sheet of unlatching or the information of closing, and as shown in Figure 6, this process mainly comprises the steps:
In this step 601, this indication information can be sent by the security module of the safety equipment shown in Fig. 5.
So far, the CLF module interface channel state that preserve to be used for identifying described CLF module and security module is the flow process end of the information of opening or closing.
In the above-mentioned steps 602 that the corresponding flow process of Fig. 6 comprises, the CLF module is verified the transmit leg of indication information can be based on authentication mechanisms such as symmetric key mechanisms, asymmetric key mechanisms, below is specifically described for the flow process based on symmetric key mechanisms, asymmetric key mechanisms checking.

Step 4, security module generate RAND2, utilize KEYROOT that the sign of CLF module is encrypted generation KEYSUB, utilize KEYSUB that RAND1||RAND2 is encrypted session key generation KEYSession, and utilize KEYSession interface channel to be opened or closed (Open/Close Channel) command body and process generation MAC1;
After step 6, CLF module are received Open/Close Channel order, utilize KEYSUB that RAND1||RAND2 is encrypted session key generation KEYSession, utilize KEYSession that Open/Close Channel command body is processed and generate MAC2, then compare MAC1 and MAC2, if MAC1 equates then to open or close according to instruction the appointment interface channel of CLF module and security module with MAC2, otherwise returns error message;
Step 7, CLF module are returned to security module and are carried out response message (Response).
So far, the flow process of based on symmetric key mechanisms the transmit leg of indication information being verified finishes.
Two, based on asymmetric key mechanisms the transmit leg of indication information is verified
Fig. 8 shows the schematic flow sheet of the transmit leg of indication information being verified based on asymmetric key mechanisms, particularly, preset the sign of publisher's certificate (containing publisher's PKI) or publisher's PKI KEYPUB, CLF module in the CLF module, preserve publisher's private key KEYPRIVATE in the security module.As described in Figure 8, this proof procedure mainly comprises the steps:
Step 3, CLF module are returned response message (Response) to security module, carry the RAND1 of generation, the sign ID of CLF module in this response message;
Step 4, security module generate RAND2, and the cryptographic hash of utilizing KEYPRIVATE interface channel to be opened or closed (Open/Close Channel) command body is encrypted and generates signature MAC1;
After step 6, CLF module are received Open/Close Channel order, utilize KEYPUB that MAC1 is decrypted, the cryptographic hash of calculation command body, compare with decrypted result, if both equate then the appointment interface channel according to instruction On/Off CLF module and security module, otherwise return error message;
Step 7, CLF module are returned to safety equipment and are carried out response message (Response).
So far, the flow process of based on asymmetric key mechanisms the transmit leg of indication information being verified finishes.
According to above-mentioned processing procedure, can control flexibly the closure or openness of the interface channel of CLF module and security module, thereby improve security module and the efficiency of management of swiping the card and using.
Based on above-mentioned processing procedure, the CLF module has been preserved the information of interface channel state for opening or closing that is used for sign CLF module and security module, particularly, the CLF module has been preserved the interface channel state that is used for sign CLF module and security module and can have been preserved in the lump with the corresponding relation of security module sign and application identities for the information of opening or closing, for example, as shown in table 3 below:
Table 3
| Application identities | The security module sign | The interface channel state |
| 0xD1560001018003800000000100000001 | SE | Open |
| 0xD1560001018003800000000100000002 | SIM | Open |
| 0xD1560001018003800000000200000003 | SD | Close |
The content of preserving according to table 3 as can be known, the interface channel between CLF module and security module SE and the security module SIM card is in opening, and is namely available, the interface channel between CLF module and the security module SD is in closed condition, and is namely unavailable.
According to said process, if close the link between CLF module and certain security module, then in the corresponding relation (or being called the order routing table) of preserving, be set to " closing " with " interface channel state " mark of this security module relevant entries, if it is default application that certain on this security module (or some) is used, then the user need to select default application from the remaining list item of order routing table, if the list item that does not satisfy condition is not then carried out this step.If open the link between CLF module and certain security module, then in the order routing table, be set to " unlatching " with " interface channel state " mark of this security module relevant entries, if in these list items certain (or some) application identities in the order routing table, do not have default application then the user need to select default application, if the list item that does not satisfy condition is not then carried out this step.
Can be successfully the noncontact order of swiping the card be processed in order to guarantee security module, before the step 103 that execution graph 1 corresponding flow process comprises, namely be sent to before the security module corresponding with the security module determined sign process in noncontact the is swiped the card order of CLF module, also the further following process of execution:
According to the information of the interface channel state that is used for sign CLF module and security module for opening or closing of preserving, from security module corresponding to the security module sign of determining, select the security module of interface channel state for opening;
So, correspondingly, above-mentioned steps 103 is when carrying out, being the CLF module is sent to the noncontact order of swiping the card the security module corresponding with the security module sign of determining and processes, and the order of specifically this noncontact being swiped the card is sent to the interface channel state of selecting and processes for the security module of unlatching.
