Description

A method and device for controlling NFC routing

technical field

The present invention relates to the technical field of terminals, in particular to a method and device for controlling routing of Near Field Communication (NFC).

Background technique

Recently, NFC technology has developed rapidly, and the card simulation function of NFC has also been used more and more. NFC card emulation can have multiple execution environments (NFCEE), but can be divided into host-based card emulation (Host-based Card Emulation, HCE) type and secure element (Secure Element, SE, hardware-based for implementing security) There are two types of card emulation smart card chip) types. Among them, the HCE type is simulated by the host, and the operating system can control the process of card simulation, but SE is an independent smart card chip, and the SE type of card simulation operation, SE can simulate the front end through near-field communication without the operating system The chip (ContactLess Front-end, CLF) directly interacts with the NFC card reader, so there are certain security risks, that is, the user cannot control this process.

Specifically, at present, regardless of the card simulation application of the HCE type or the SE type, a set of application unique identifiers (Application ID, AID) will be registered, and a routing table exists in the NFC chip. The routing table records the direction in which each AID needs to be routed. The routing direction can be the host (corresponding to HCE) or a certain SE. There is also a default routing setting. If an AID cannot be found in the routing table, Then follow the default route to route.

The current common practice is to write the AID of HCE or SE into the routing table, and then set the default route as SE or HCE, so that there is no need to store all AIDs in the routing table, which can save the space of the routing table. Fig. 1 is the relationship diagram of NFC card reader, CLF and HCE, SE provided by prior art, as shown in Fig. 1, the instruction of NFC card reader is sent to CLF, and CLF determines whether to route to HCE or SE according to the situation of routing table Each SE.

Generally speaking, the terminal product will set the default route when it leaves the factory, and the current default route is generally set to SE. If the default route is SE and all HCE-related AIDs are written into the routing table, then all SE-related AIDs can interact with the NFC card reader directly through the CLF without being controlled by the operating system. There may be multiple payment-type applications in SE, but users do not necessarily want to use all payment-type applications, or hope to be able to dynamically select payment applications by themselves. Since the interaction between the SE and the NFC card reader will not be 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 into the routing table, the situation is similar to the above. All SE-related AIDs can interact with the card reader directly through CLF without the control of the operating system.

Wherein, 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 provided by an embodiment of the present invention, as shown in Fig. 3 , including:

The acquiring module 10 is configured to determine the SE-type applications that the user needs to disable. Specifically, the acquisition module 10 displays the SE-type applications that it supports to the user, for example, the AID and/or chart of the SE-type applications, etc., so that the user can select the SE-type applications that need to be disabled or need to be dynamically selected, Thus, the terminal determines the SE-type application that needs to be disabled or dynamically selected by the user.

The adjustment 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 adjustment module 20 adjusts the default route in the routing table to HCE and needs to disable the SE type of application, determines that the SE type of application that does not need to be disabled is determined, and the SE type that does not need to be disabled Write to the routing table. Further, the adjustment module 20 is further configured to delete the HCE-type application in the routing table.

The processing module 30 is configured to send an instruction for selecting an application from the NFC card reader according to the modified routing table. When the processing module 30 receives an instruction from the NFC card reader for selecting an application of the SE type, it queries the modified routing table, and if there is no application of the SE type in the modified routing table, It means that the SE-type application is an application that needs to be disabled or dynamically selected by the user. At this time, according to the default route in the modified routing table, the instruction is sent to the HCE for the operating system to process the Instructions, if the SE-type application exists in the modified routing table, it means that the SE-type application is the application that the user wants to use, and at this time, the instruction is sent according to the modified routing table To SE, for processing by the application of the SE type selected by the NFC card reader. When the processing module 30 receives an instruction from the NFC card reader for selecting an application of the HCE type, according to the default route in the modified routing table, the instruction is sent to the HCE for the NFC to read The application of the HCE type selected by the carder is processed.

The embodiment of the present invention will be further described below with reference to FIG. 4 to FIG. 6 .

In practical application, the embodiment of the present invention may include a setting module (capable of realizing the function of the acquisition module 10 in FIG. 3 ) and a routing control module (capable of realizing the functions of the adjustment module 20 and the processing module 30 in FIG. 3 ).

The setting module is an interactive interface provided to the user. According to the situation of the setting module, the routing control module performs different controls.

The routing control module is a module for actual operation. According to the information provided by the setting module, the routing table is operated to complete the problem to be solved by the embodiment of the present invention.

The setting module will list and display to the user all SE-related AIDs or applications supported by the current terminal, and display the current status of AIDs or applications. By default, all AIDs and applications are activated. The user can choose to disable one or more AIDs or applications. After the user operation is completed, the setting module sends the user's operation result to the routing control module for processing.

The routing control module will modify the setting of the routing table according to the setting of the user. If the user disables a certain AID or application, the routing control module will switch the default route to HCE, and write all 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 banned by the user, it will be routed to the operating system, and the operating system can take a discard request, reply a rejection, or prompt the user whether to activate the relevant application according to the user's preference and so on.

Fig. 4 is a routing diagram of each AID in the initial situation provided by the embodiment of the present invention. As shown in Fig. 4, the user terminal has the HCE function and the SE, AID1 and AID2 of the multifunctional integrated circuit card (Universe Integrate Circuit Card, UICC) Corresponding to the applications APP1 and APP2 of the HCE, AID3 and AID4 respectively corresponding to the applications APP3 and APP4 of the UICC. The current default route is set to UICC, and the information stored in the routing table is that AID1 and AID2 are routed to HCE. In this case, if the NFC card reader SELECT AID1 or AID2, it will be routed to the operating system, and APP1 or APP2 will respond to the request (that is, the instruction for SELECT AID1 or AID2); if the card reader SELECT AID3 Or AID4, then it will be routed to UICC, and APP3 or APP4 in UICC will respond to the request. This process is completed without the intervention of the operating system. As shown in Figure 4, the routing directions of AID1 and AID2 are shown by the arrows pointing to APP1 and APP2 respectively in Figure 4. The request of the NFC card reader is to reach HCE, and the routing directions of AID3 and AID4 are respectively shown in Figure 4. As indicated by the arrows pointing to APP3 and APP4, the request from the NFC reader reaches the UICC.

If the user does not want to use APP2 for the time being, the user can simply intercept the SELECT AID2 command through the setting of the operating system and not send it to APP2; but if the user does not want to use APP3 for the time being, because the SELECT APP3 command can not be processed by the operating system , which is directly responded by APP3 in UICC, which cannot be controlled by the user unless the card simulation function of NFC is turned off.

Fig. 5 is a schematic diagram of changes in the routing table provided by the embodiment of the present invention. As shown in Fig. 5, in the routing table in the initial situation, the current default route is set to UICC, and the information stored in the routing table is that AID1 and AID2 are routed to HCE. Using the embodiment of the present invention to perform the following operations: switch the default route to HCE, clear the information of AID1 and AID2 in the routing table, and then write the route of AID4 to the UICC in the routing table.

Fig. 6 is a diagram of the routing situation of each AID after the routing table is changed provided by the embodiment of the present invention. 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 will be routed to HCE, It is processed by APP1 and APP2; the SELECT request for AID3 will be routed to HCE, and the operating system can choose to discard the request, reply to reject, or prompt the user whether to activate the relevant application; the SELECT request for AID4 will still be routed to UICC, Handled normally by APP4. As shown in Figure 6, the routing directions of AID1 and AID2 are shown by the arrows pointing to APP1 and APP2 respectively in Figure 6, and the request from the NFC card reader reaches HCE; the routing direction of AID4 points to APP4 in Figure 6 As shown by the arrow, the request from the NFC card reader arrives at the UICC; the routing direction of AID3 will be routed to the HCE. It is up to the operating system to decide whether to reject, discard or prompt the user for this request.

SE may include various bearers such as UICC, SD, and eSE, and the terminal may also use one or more of them. For the embodiment of the present invention, no matter what the default route is in the initial state, if it is necessary to disable the AID or application in the SE, it is possible to set the default route as HCE, and then set the AID or application other than the AID or application that needs to be disabled. All SE AIDs or applications are written into the routing table.

Although the present invention has been described in detail above, the present invention is not limited thereto, and various modifications can be made by those skilled in the art based on the principle of the present invention.
