Referring to Fig. 4, it is an embodiment flow chart of another kind of NFC card data reading and writing method that the embodiment of the present disclosure provides, and the flow process shown in this Fig. 4 is based on the flow process shown in above-mentioned Fig. 2 and Fig. A kind of realization mode that SE chip is authenticated may comprise the following steps:

Step 401, when the NFC mobile terminal receives the NFC card data writing request, it parses out the NFC card data to be written from the NFC card data writing request.

Step 402, the NFC mobile terminal sends the CPLC value of the SE chip and the data of the NFC card to the security server.

The CPLC value represents the ID of the SE chip, and each SE chip has a unique CPLC value.

Optionally, the NFC mobile terminal 10 can encode the NFC card data according to the corresponding file format, assign a corresponding identification and upload it to the security server 20 . Here, the file format includes but is not limited to picture, text, audio and so on. The identification can be used to characterize the type, quantity, etc. of the NFC card data.

It should be noted that, in the embodiment of the present disclosure, there is no limitation on the execution order of the NFC mobile terminal 10 sending the CPLC value of the SE chip 12 and the NFC card data to the security server 20 .

Step 403, the security server authenticates the SE chip based on the CPLC value and using a preset authentication process.

It can be known from the above description that the CPLC value represents the ID of the SE chip. Therefore, after receiving the CPLC value, the security server 20 can know which SE chip is to be authenticated. That is to say, the security server 20 authenticates the SE chip corresponding to the received CPLC value, such as the SE chip 12 . Wherein, the security server 20 can use a preset authentication process to authenticate the SE chip 12 corresponding to the received CPLC value.

Optionally, the aforementioned preset authentication process is an authentication process defined by the GPC protocol. For a specific authentication process, reference may be made to relevant descriptions in the prior art, and details are not repeated here.

In step 404, the security server writes the NFC card data into the SE chip after determining that the SE chip has been authenticated.

In some embodiments, after the security server 20 determines that the SE chip 12 is authenticated, it first issues a check instruction to the NFC mobile terminal 10, and the check instruction is used to instruct to check whether there is an NFC code to be written in the SE chip 12. The target smart card application (applet) and security domain corresponding to the card data.

If it exists, the security server 20 writes the NFC card data into the target smart card application program in the SE chip 12 .

If not, the security server 20 can send a CAP data packet to the NFC mobile terminal 10, and the NFC mobile terminal 10 can instantiate the above-mentioned target smart card application in the SE chip 12 based on the CAP data packet. Afterwards, the security server 20 writes the NFC card data into the target smart card application program in the SE chip 12 .

The above-mentioned CAP data packet refers to a file with a suffix of .cap, which can be understood as a logic code file written according to the JAVA CARD protocol. After being loaded into the SE chip 12, an executable file called a smart card application can be generated by an instantiation instruction. The smart card application is responsible for the data interaction logic with the card reader device.

In addition, when the NFC card data is successfully written into the target smart card application program in the SE chip, the display interface of the upper layer application 14 can output a prompt message for prompting the user that the NFC card data is saved successfully.

Through the process shown in FIG. 4 , the authentication of the SE chip built in the NFC mobile terminal by the security server is realized.

Referring to Fig. 5, it is an embodiment flowchart of another kind of NFC card data reading and writing method that the embodiment of the present disclosure provides, and the flow process shown in this Fig. 5 is based on the flow process shown in above-mentioned Fig. 2 and Fig. 3, emphatically describes another An implementation of authenticating an SE chip may include the following steps:

Step 501, when the NFC mobile terminal receives the NFC card data writing request, it parses out the NFC card data to be written from the NFC card data writing request.

Step 502, the NFC mobile terminal sends a key acquisition request to the security server, and the key acquisition request carries the CPLC value of the SE chip.

Step 503, the security server returns the SE chip key corresponding to the received CPLC value to the NFC mobile terminal.

Step 504, the NFC mobile terminal authenticates the SE chip based on the received SE chip key and uses a preset authentication process.

The SE chip keys mentioned above include but are not limited to ENC keys, MAC keys, DEK keys, etc.

The aforementioned preset authentication process is the same as the authentication process mentioned in the embodiment shown in FIG. 4 .

The difference between the process shown in FIG. 5 and the process shown in FIG. 4 is that the security server 20 authenticates the SE chip 12 in the process shown in FIG. 4 , while in the process shown in FIG. 5 , the NFC mobile terminal 10 authenticates the SE chip 12 authentication. Accordingly, in the process shown in FIG. 4 , the NFC mobile terminal 10 first sends a key acquisition request to the security server 20 , and the key acquisition request carries the CPLC value of the SE chip 12 to request to acquire the SE chip key of the SE chip 12 . Afterwards, after receiving the key acquisition request, the security server 20 returns to the NFC mobile terminal 10 the SE chip key corresponding to the received CPLC value, that is, the key of the SE chip 12 . After that, the NFC mobile terminal 10 authenticates the SE chip 12 based on the received SE chip key and uses a preset authentication process.

Step 505, after the NFC mobile terminal confirms that the SE chip is authenticated, writes the NFC card data to be written into the SE chip.

In some embodiments, after the NFC mobile terminal 10 determines that the SE chip 12 is authenticated, it first checks whether there is a target smart card application program and a security domain corresponding to the NFC card data to be written in the SE chip 12 .

If it exists, the NFC mobile terminal 10 writes the NFC card data into the target smart card application program in the SE chip 12 .

If it does not exist, the NFC mobile terminal 10 can download the CAP data packet from the security server 20, then instantiate the above-mentioned target smart card application program in the SE chip 12 based on the CAP data packet, and then, the NFC mobile terminal 10 writes the NFC card data into the target smart card application in the SE chip 12.

Through the process shown in FIG. 5 , the NFC mobile terminal authenticates its built-in SE chip.

Referring to Fig. 6, it is a flowchart of an embodiment of another method for reading and writing NFC card data provided by an embodiment of the present disclosure. The process shown in Fig. 6 is based on the process shown in Fig. 2 above, emphatically describing the NFC mobile terminal at the same time. The interaction process between NFC card readers may include the following steps:

Step 601, when the NFC mobile terminal receives the NFC card data write request, it parses the NFC card data to be written from the NFC card data write request, and writes the NFC card data to be written into the SE chip.

Step 602: When receiving the NFC card data reading request from the NFC card reading device, the NFC mobile terminal sends an acquisition request to the NFC card reading device.

The acquisition request above is used to instruct to acquire the valid contactless key of the target smart card application program stored in the NFC card reading device.

Step 603, the NFC mobile terminal receives a valid non-contact key from the NFC card reading device.

Step 604, the NFC mobile terminal compares the received effective non-connected key with the target effective non-connected key stored in the NFC mobile terminal, if the two are found to be consistent, step 605 is performed; if the two are found to be inconsistent, then end the process.

Step 605, the NFC mobile terminal determines that the authentication of the NFC card reading device is passed.

Step 606, the NFC mobile terminal sends the NFC card data to the NFC card reading device.

The effective contactless keys of different smart card application programs are different. If the NFC card reader device 30 holds the effective contactless key of the target smart card application program in the SE chip 12, it means that the NFC card reader device 30 applies the target smart card key to the target smart card. The program has read permissions. Therefore, the NFC mobile terminal 10 can authenticate the NFC card reader 30 by determining whether the NFC card reader 30 holds a valid contactless key of the target smart card application in the SE chip 12 .

Specifically, when the NFC mobile terminal 10 is close to the NFC card reader 30, the NFC card reader 30 can first send a select command to the NFC mobile terminal 10, and the select command is used to indicate the smart card where the NFC card data to be read is obtained. The AID of the application. Wherein, the select command is received by the NFC chip 11 in the NFC mobile terminal 10 and passed to the SE chip 12 .

Afterwards, the SE chip 12 responds to the above select command, sends the AID of the smart card application program to the NFC chip 11 in the NFC mobile terminal 10 , and the NFC chip 11 transmits it to the NFC card reading device 30 .

Further, after the NFC card reading device 30 receives the above-mentioned AID, the target smart card application program in the SE chip 12 can authenticate the NFC card reading device 30 .

Specifically, the SE chip 12 sends an acquisition request to the NFC chip 11 through the target smart card application program, and the above acquisition request is used to indicate acquisition of the target effective contactless key of the target smart card application program stored in the NFC card reader device, and the NFC chip 11 will The acquisition request is passed to the NFC card reading device 30, so that the NFC card reading device 30 returns the corresponding valid contactless key based on the above-mentioned received AID.

Further, the NFC mobile terminal 10 receives the effective non-contact key from the NFC card reading device 30, and compares the received effective non-contact key with the target effective non-connection key stored in the NFC mobile terminal 10, if the comparison results in If the two are consistent, step 605 is executed; if the two are not consistent, the process ends.

In addition, in the above data interaction logic, since only the NFC chip 11 and the SE chip 12 are required to participate, even if the NFC mobile terminal 10 is turned off, the above data interaction logic can be executed normally.

Through the process shown in Figure 6, the NFC mobile terminal authenticates the NFC card reader device, so that only the authentication passes, that is, the legal NFC card reader device can obtain the NFC card data, effectively guaranteeing the NFC card data The security can prevent NFC card data from being maliciously leaked.
