Description
Technical Field
The present invention relates to the field of terminal technologies, and in particular, to a method and an apparatus for controlling Near Field Communication (NFC) routing.
Background
Recently, NFC technology has been developed rapidly, and card emulation functions of NFC are increasingly used. Card Emulation for NFC may have multiple execution environments (NFCEE), but may be classified into two types, a Host-based Card Emulation (HCE) type and a Secure Element (SE, a smart Card chip for implementing Secure Card Emulation based on hardware) type. The HCE type is host simulation, the operating system can control the card simulation process, the SE is an independent intelligent card chip, the SE type card simulation operation can be realized, the SE can directly interact with the NFC card reader through a near field communication simulation Front-end Chip (CLF) without passing through the operating system, and therefore certain potential safety hazards exist, namely a user cannot control the process.
Specifically, currently, whether card emulation applications are HCE type or SE type, a set of Application unique identifiers (AIDs) is registered, and a routing table exists in the NFC chip. The routing table records the direction in which each AID needs to be routed, where the routing direction may be a host (corresponding to the HCE) or a certain SE, and also has a default routing setting, and if a certain AID cannot be found in the routing table, the routing is performed according to the default routing.
At present, the common practice is to write the AID of the HCE or SE into the routing table, and then set the default route as the SE or HCE, so that all AIDs do not need to be stored in the routing table, and the space of the routing table can be saved. Fig. 1 is a relationship diagram between an NFC card reader and a CLF and an HCE and an SE provided in the prior art, and as shown in fig. 1, an instruction of the NFC card reader is sent to the CLF, and the CLF determines whether to route to the HCE or each SE according to the condition of a routing table.
Generally, a default route is set when an end product leaves a factory, and the default route is generally set to SE at present. If the default route is SE and all HCE related AIDs are written to the routing table, then all SE related AIDs may interact with the NFC reader directly through CLF by SE without control of the operating system. There may be multiple payment type applications in the SE, but the user does not necessarily want to use all payment type applications, or wants to be able to dynamically select payment applications on their own. Since the interaction between the SE and the NFC reader is not controlled by the operating system, it is impossible for the user to dynamically select whether the payment application in the SE is activated.
If the default route is HCE and all SE-related AIDs are written to the routing table, the situation is similar as above, and all SE-related AIDs can interact with the reader directly through CLF by SE without control of the operating system.

Detailed Description
The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, and it should be understood that the preferred embodiments described below are only for the purpose of illustrating and explaining the present invention, and are not to be construed as limiting the present invention.

step S101: the terminal determines the application of the type of security element SE that the user needs to disable.
The terminal enables the user to select the applications of the SE type which need to be disabled or need to be dynamically selected by showing the applications of the SE type supported by the terminal to the user, for example, showing AIDs and/or icons of the applications of the SE type to the user, so that the applications of the SE type which need to be disabled or need to be dynamically selected by the user are determined.
Step S102: and the terminal modifies the routing table according to the application of the SE type needing to be forbidden, so that the application of the SE type needing to be forbidden is routed to the operating system.
And the terminal adjusts the default route in the routing table to be HCE, determines the application of the SE type which does not need to be forbidden according to the application of the SE type which needs to be forbidden, and writes the application of the SE type which does not need to be forbidden into the routing table, so that the application of the SE type which does not need to be forbidden can be routed to a specified target according to the routing table, and the application of the SE type which needs to be forbidden and the application of the HCE are routed to the HCE.
Further, the terminal deletes the application of the HCE type in the routing table.
Step S103: and the terminal sends an instruction for selecting a certain application from the NFC card reader according to the modified routing table.
And when the NFC card reader sends an instruction for selecting the SE type application to the terminal, the terminal inquires whether the application of the SE type exists in the modified routing table or not according to the instruction, if the application of the SE type exists, the instruction is sent to the corresponding SE according to the modified routing table so that the application of the SE type selected by the NFC card reader can process the instruction, otherwise, the instruction is sent to the HCE according to the default route in the modified routing table so that an operating system can process the instruction.
And when the NFC card reader sends an instruction for selecting the HCE type application to the terminal, the terminal sends the instruction to the HCE according to the instruction and the default route in the modified route table, so that the HCE type application selected by the NFC card reader can process the instruction.
It will be understood by those skilled in the art that all or part of the steps in the method according to the above embodiments may be implemented by a program, which may be stored in a computer-readable storage medium, and includes steps S101 to S103 when the program is executed. The storage medium may be ROM/RAM, magnetic disk, optical disk, etc.
Fig. 3 is a block diagram of an apparatus for controlling NFC routing according to an embodiment of the present invention, as shown in fig. 3, including:
and the acquisition module 10 is used for determining the SE type application which needs to be disabled by the user. Specifically, the acquiring module 10 enables the user to select the applications of the SE type that need to be disabled or need to be dynamically selected by presenting the applications of the SE type that it supports to the user, for example, AIDs and/or charts of the applications of the SE type, so that the terminal determines the applications of the SE type that the user needs to be disabled or need to be dynamically selected.
And the adjusting module 20 is configured to modify the routing table according to the application of the SE type that needs to be disabled, so that the application of the SE type that needs to be disabled is routed to the operating system. Specifically, the adjusting module 20 adjusts the default route in the routing table to be HCE and requires the disabled SE type application, determines the SE type application that does not need to be disabled, and writes the SE type application that does not need to be disabled into the routing table. Further, the adjusting module 20 is also configured to delete the HCE type application in the routing table.
And the processing module 30 is configured to send an instruction for selecting a certain application from the NFC card reader according to the modified routing table. The processing module 30, when receiving an instruction for selecting an SE type application from an NFC card reader, queries the modified routing table, and if the SE type application does not exist in the modified routing table, indicates that the SE type application is an application that a user needs to disable or needs to dynamically select, sends the instruction to the HCE according to a default route in the modified routing table, so that the instruction is processed by the operating system, and if the SE type application exists in the modified routing table, indicates that the SE type application is an application that the user wants to use, and sends the instruction to the SE according to the modified routing table, so that the SE type application selected by the NFC card reader is processed. When receiving an instruction for selecting an HCE-type application from the NFC card reader, the processing module 30 sends the instruction to the HCE according to the default route in the modified routing table, so that the HCE-type application selected by the NFC card reader can be processed.
The following further describes an embodiment of the present invention with reference to fig. 4 to 6.
In practical applications, the embodiment of the present invention may include a setting module (capable of implementing the functions of the obtaining module 10 in fig. 3) and a routing control module (capable of implementing the functions of the adjusting module 20 and the processing module 30 in fig. 3).
The setting module is an interactive interface provided for users, and the routing control module performs different controls according to the condition of the setting module.
The routing control module is a module operated actually, and operates the routing table according to the information provided by the setting module to complete the problem to be solved by the embodiment of the invention.
The setting module lists all AIDs or applications related to the SE supported by the current terminal and displays the AIDs or the applications to the user, and simultaneously displays the current states of the AIDs or the applications, wherein all the AIDs and the applications are active under the default condition. The user can choose to disable one or more AIDs or applications, and after the user operation is completed, the setting module sends the operation result of the user to the routing control module for processing.
The routing control module can modify the setting of the routing table according to the setting condition of the user. If the user forbids dropping of a certain AID or application, the routing control module switches the default route to the HCE and writes other AIDs or applications except the disabled AID or application into the routing table. In this way, if the NFC card reader SELECTs (SELECT) the AID or application prohibited by the user, the NFC card reader may be routed to the operating system, and the operating system may take an operation such as discarding the request, replying a rejection, or prompting the user whether to activate the relevant application according to the preference of the user.
Fig. 4 is a routing diagram of each AID in an initial situation provided by the embodiment of the present invention, and as shown in fig. 4, a user terminal has an HCE function and an SE of a Universal Integrated Circuit Card (UICC), AID1 and AID2 respectively correspond to applications APP1 and APP2 of the HCE, and AID3 and AID4 respectively correspond to applications APP3 and APP4 of the UICC. The current default route is set as UICC, and the information stored in the routing table is that AID1 and AID2 are routed to HCE. In this case, if NFC reader SELECT AID1 or AID2, it will be routed to the operating system and the request (i.e., instructions for SELECT AID1 or AID 2) will be responded to by APP1 or APP 2; if the card reader SELECT AID3 or AID4 were routed to the UICC and the request responded by APP3 or APP4 in the UICC, this process is done without operating system intervention. As shown in fig. 4, the routing directions of AID1 and AID2 are shown by arrows pointing to APP1 and APP2, respectively, in fig. 4, the request of the NFC reader is to the HCE, the routing directions of AID3 and AID4 are shown by arrows pointing to APP3 and APP4, respectively, in fig. 4, and the request of the NFC reader is to the UICC.
If the user does not want to use the APP2 for a while, the user can simply intercept SELECT AID2 instructions through the operating system setting, and does not send the instructions to the APP 2; however, if the user does not want to use APP3 for a while, since the instruction of SELECT APP3 can be responded directly by APP3 in the UICC without processing by the operating system, the user cannot control unless the card emulation function of NFC is turned off.
Fig. 5 is a schematic diagram illustrating a change of a routing table according to an embodiment of the present invention, as shown in fig. 5, in the routing table in an initial case, a current default route is set as the UICC, and information stored in the routing table is that the AID1 and the AID2 are routed to the HCE. The following operations are performed using the embodiment of the present invention: and switching the default route to HCE, clearing the information of AID1 and AID2 in a routing table, and writing AID4 in the routing table to route to UICC.
Fig. 6 is a routing situation diagram of each AID after the routing table provided by the embodiment of the present invention is changed, as shown in fig. 6, the problem in fig. 4 can be solved through the above operations, and the SELECT requests for AID1 and AID2 are routed to the HCE and processed by APP1 and APP 2; for the option 3, the SELECT request may be routed to the HCE, and the operating system may choose to discard the request, reply a rejection, or prompt the user whether to activate the relevant application; SELECT requests for AID4 will still be routed to the UICC, processed normally by APP 4. As shown in fig. 6, routing directions of AID1 and AID2 are shown as arrows pointing to APP1 and APP2, respectively, in fig. 6, and a request of an NFC reader arrives at the HCE; routing direction of AID4 as shown by the arrow pointing to APP4 in fig. 6, the request of NFC reader is to UICC; the routing direction of the AID3 will be routed to the HCE, whether the request is denied, discarded or prompted to the user as may be determined by the operating system.
The SE may include various bearers such as UICC, SD, eSE, etc., and the terminal may use one or more of the SEs. For the embodiment of the present invention, no matter what the default route is in the initial state, if it is required to disable the AIDs or applications in the SE, the default route may be set to the HCE, and then the AIDs or applications of all SEs except the AIDs or applications that need to be disabled may be written into the routing table.
Although the present invention has been described in detail hereinabove, the present invention is not limited thereto, and various modifications can be made by those skilled in the art in light of the principle of the present invention. Thus, modifications made in accordance with the principles of the present invention should be understood to fall within the scope of the present invention.
