Further, the card pool can be updated periodically or aperiodically according to the requirement of the user; or the card pool can be updated according to the card swiping result of the card reading device, for example, if the card swiping result of all the card identifications in the card selection recommendation table is card swiping failure, the user may need to manually add a new card matched with the card reading device, and trigger a card adding instruction to adjust the card pool by the security element.

In the embodiment of the disclosure, the intelligent card selecting model can be used for selecting cards for users in advance, automatically realizing card switching, reducing time consumption of card swiping of users, and improving card swiping experience of the users.

In step S103, the near field communication controller responds to the first card swiping request with the first non-access protocol parameter.

In the embodiment of the disclosure, after receiving the first card swiping request, the near field communication controller responds to the first card swiping request by using the first non-access protocol parameter, so that the card reading device performs anti-collision verification on the first non-access protocol parameter and returns an anti-collision verification result to the near field communication controller.

The card swiping process of the first type card comprises anti-collision check and business check, the card swiping process of the second type card comprises anti-collision check and authentication check, and the card swiping process of the third type card only comprises anti-collision check.

Step S502, judging whether the checking instruction is a business instruction, if so, turning to step S503; if not, go to step S504.

Step S503, matching the target application identifier, and reading the service parameter of the target application identifier to respond to the service instruction.

In the embodiment of the present disclosure, the verification instruction is a service instruction, which indicates that the card type corresponding to the card reading device is a type one card, that is, a service card, and the security element responds to the service instruction by using a service parameter identified by the target application, as shown in fig. 6, a processing method of the service instruction of the present disclosure includes the following steps:

in step S601, the secure element receives a service instruction.

In the embodiment of the disclosure, in the case that the verification instruction is a service instruction, the card type corresponding to the card reading device is a type one card.

Step S602, the secure element determines whether the card selection data set has an update, and if yes, goes to step S603; if not, go to step S610.

In the embodiment of the disclosure, the security element can determine that the card selection data set is updated as long as any one of the signal frequency, the signal envelope, the signal slope, the signal phase, the signal radio frequency power, the geographic location, the geomagnetism, and the card pool is changed.

In step S603, the secure element inputs the updated card selection data set into the smart card selection model, so as to obtain a second recommendation table output by the smart card selection model.

In the embodiment of the disclosure, in the case that the card selection data set is updated, the security element inputs the updated card selection data set into the intelligent card selection model to obtain the second recommendation table.

In step S604, the secure element matches a target application identifier from the second recommendation table.

In the embodiment of the disclosure, one card may correspond to at least one application identifier, and in the case that one card corresponds to a plurality of application identifiers, application parameters corresponding to the plurality of application identifiers in the secure element are the same, where the application parameters include a non-access protocol parameter, a service parameter, and the like. Therefore, in the case where one card corresponds to a plurality of application identifications, one is generally selected from the plurality of application identifications as the application identification corresponding to the card identification.

Further, the secure element determines whether to look up a default application identifier from the second recommendation table as a target application identifier or to look up an application identifier matching the local application identifier of the service instruction from the second recommendation table as a target application identifier according to whether the service instruction includes the local application identifier. The default application identifier is pre-selected and can be selectively set according to the use frequency of the card, different use scenes and the like.

Further, when the service instruction does not include the local application identifier, the secure element searches the default application identifiers from the second recommendation table as target application identifiers, and uses the default application identifiers found from the application identifiers corresponding to the card identifiers in the second recommendation table as target application identifiers one by one.

Or when the service instruction comprises the local application identifier, the safety element searches the second recommendation table for the application identifier matched with the local application identifier of the service instruction as a target application identifier, compares the local application identifier with the application identifiers corresponding to the card identifiers of the second recommendation table one by one, judges whether the local application identifier can be locally matched with each application identifier corresponding to the second recommendation table, and takes the application identifier which can be locally matched, namely comprises the local application identifier as the target application identifier. For example, the application identifiers corresponding to the card identifiers are 000, 225637, 551, 565637, 452, 458612, the local application identifier is 5637, and then 000, 225637, 551, 565637 are individually used as the target application identifier, and 452, 458612 is not used as the target application identifier.

In the embodiment of the disclosure, the secure element directly determines that the card swiping result of the first card swiping request is card swiping failure under the condition that the application identifier corresponding to each card identifier of the second recommendation table is determined to have no default application identifier or cannot be matched with the local application identifier locally.

Further, a prompt of ' default application identification does not exist ', card swiping failure ' or ' local application identification matching failure ' is fed back to the front end of the electronic equipment, and a user resets the default application identification or adds a new card matched with the card reading equipment to the card pool so as to facilitate smooth card cutting.

Step S605, the secure element reads the service parameter of the target application identifier, and sends the service parameter to the card reading device through the near field communication controller.

In the embodiment of the disclosure, the security element sends the first service parameter to the near field communication controller, and then the near field communication controller sends the first service parameter to the card reading device, so that the security element can transmit the first service parameter to the card reading device through the near field communication controller.

Step S606, the near field communication controller receives a service verification result returned by the card reading device for performing service verification on the service parameter, determines whether the service verification result is successful, and if yes, goes to step S607; if not, go to step S608.

In step S607, the near field communication controller determines that the card swiping result of the first card swiping request is successful card swiping.

In the embodiment of the disclosure, under the condition that the service verification result is verification success, the card reading device is forbidden, and the card swiping of the first card swiping is successful, so that the near field communication controller can directly determine that the card swiping result of the first card swiping request is the card swiping success.

Further, after the card is successfully swiped, the method further comprises the following steps:

In step S608, the near field communication controller sends the service verification result to the secure element.

In the embodiment of the present disclosure, in the case that the first service verification result is verification failure, card re-selection is required, so that the near field communication controller sends the first service verification result that the verification fails to the secure element.

In step S609, the secure element triggers a false departure operation.

In the embodiment of the disclosure, under the condition that the card reading device is forbidden and the card swiping is successful, the near field communication controller can directly determine the card swiping result of the card swiping success without sending the card swiping result to the security element, so the security element only receives the service verification result of the verification failure, and the security element triggers the false-off-site operation in response to the service verification result of the verification failure, so that the card reading device leaves the signal field of the card reading device for the electronic device, and then the electronic device enters the signal field of the card reading device, and at the moment, the card reading device can initiate a second card swiping request to the electronic device after the false-off-site operation again.

Further, in the case that the service verification result is not received, the secure element may directly determine that the card swiping result of the first card swiping request is successful.

In step S610, the secure element matches the target application identifier from the first recommendation table, and goes to step S605.

In the embodiment of the disclosure, in the case that no update exists in the card selection data set, the security element matches a default application identifier from the first recommendation table as a target application identifier, or matches an application identifier matched with the local application identifier of the service instruction from the first recommendation table as a target application identifier. The method for matching the target application identifier in the first recommendation table is the same as the method for matching the target application identifier in the second recommendation table, and will not be described herein.

In the embodiment of the disclosure, by the processing method of the service instruction of the disclosure, the security element decides whether to match the target application identifier in the recommendation table before or after updating according to whether the card selection data set is updated, further reads the corresponding service parameter to respond to the service instruction, decides whether to trigger the false leaving operation according to the service check result of the card reading device, and re-accepts the card swiping request of the card reading device, and re-performs the anti-collision check by using the first non-access protocol parameter which is checked successfully, so as to reciprocate until the final card swiping result of a card is determined, thereby realizing intelligent card cutting, improving the card selection efficiency and improving the card cutting performance.

In the embodiment of the present disclosure, after the verification result of the service verification is that the verification fails, the security element triggers the false departure operation, according to whether the reason generated by the service verification result of the verification failure is related to the first non-access protocol parameter, the security element and the near field communication controller trigger different response actions, as shown in fig. 7, the response method of the false departure operation of the service instruction of the present disclosure includes the following steps:

Step S701, the security element determines whether the verification result of the service verification is that the reason of the verification failure is related to the first non-access protocol parameter, and if so, goes to step S702; if not, go to step S705.

In step S702, the secure element updates the first non-access protocol parameter and sends the updated first non-access protocol parameter to the nfc controller.

In the embodiment of the disclosure, when the secure element determines that the reason for the verification failure of the service verification is related to the first non-access protocol parameter, the first non-access protocol parameter needs to be updated, and the updated first non-access protocol parameter is sent to the near field communication controller to respond to the card reading device.

Further, the secure element determines an updated first non-access protocol parameter based on whether the card selection data set is updated, wherein:

Under the condition that the card selection data set is updated, the safety element inputs the updated card selection data set into the intelligent card selection model, reselects a second target card which is different from the first target card from a second recommendation table output by the intelligent card selection model, and reads the non-access protocol parameters of the second target card as updated first non-access protocol parameters;

Or under the condition that the card selection data set is not updated, reselecting a second target card which is different from the first target card from the first recommendation table, and reading the non-access protocol parameters of the second target card as updated first non-access protocol parameters.

In step S703, the near field communication controller receives a second card swiping request triggered by the card reading device after the false off-field operation.

In step S704, the nfc controller responds to the second card swiping request with the updated first non-access protocol parameter.

Step S705, the near field communication controller receives a second card swiping request triggered by the card reading device after the false off-field operation.

In the embodiment of the disclosure, when the security element determines that the reason of the service verification failure is unrelated to the first non-access protocol parameter, the first non-access protocol parameter is not required to be updated, and the near field communication controller still responds to the card reading device by using the first non-access protocol parameter which is successfully subjected to the previous anti-collision verification, so that the consumption of time, communication and other costs for requesting the non-access protocol parameter from the security element again is avoided, and the card cutting performance is improved.

In step S706, the near field communication controller responds to the second card swiping request with the first non-access protocol parameter.

In the embodiment of the disclosure, when the first non-access protocol parameter which is successful in the previous anti-collision verification is used for responding to the second card swiping request again, the verification result of the anti-collision verification is necessarily successful, so that the near field communication controller directly and thoroughly transmits the service instruction carried in the anti-collision verification result to the security element again, and the service verification process is repeated until the card swiping is successful.

In the embodiment of the disclosure, by the response method of the false departure operation of the service instruction, for the false departure operation triggered by the security element, according to whether the reason of the false departure is related to the first non-access protocol parameter, different operations such as updating the first non-access protocol parameter or responding to the card reading equipment by using the old first non-access protocol parameter are executed, so that the success of service verification is ensured, the quick response and the card selection success rate of the card cutting are realized, and the card cutting performance is improved.

Step S504, in response to the authentication instruction, the secure element generates an element random number, and performs authentication verification through interaction between the near field communication controller and the card reading device.

Wherein, the element random number is an integer, the value range is-2147483648 ～ 2147483647 (namely-2 ³¹～2³¹ -1), and 4 bytes (namely 32 bits) are occupied.

In step S803, the near field communication controller receives the encryption result returned by the card reading device, and sends the encryption result to the secure element.

In the embodiment of the disclosure, when the card reading device issues the authentication instruction, the card reading device generates a card reading random number, and performs data operation on the card reading random number to obtain an encrypted ciphertext.

Further, the data operation refers to the subsequent function calculation of 64 bits on the card reading random number.

Further, after receiving the element random number, the card reading device encrypts the encrypted ciphertext by using the card reading random number, the element random number, the card reading key and the application identifier of the first non-access protocol parameter which corresponds to the authentication instruction and is successfully checked, so as to obtain an encryption result.

In step S804, the secure element performs authentication verification on the encryption result.

In the embodiment of the present disclosure, the essence of authentication verification is essentially the inverse operation of the encryption operation of the card reading device.

And S8041, decrypting the encryption result by using the application identifier corresponding to the first non-access protocol parameter, the element random number and the agreed element key to obtain an encrypted ciphertext and a decrypted random number.

Further, the decryption algorithm of the secure element is the same as the encryption algorithm of the card reading device, and the card reading device and the secure element pre-agree on encryption/decryption keys, and store the card reading key and the element key in the card reading device and the secure element respectively.

In the embodiment of the disclosure, under the condition that the verification result of the authentication verification is verification success, determining that the card swiping result of the first card swiping request is card swiping success.

Further, since the authentication instruction corresponds to the second type card, after the second type card is successfully swiped, the method further comprises:

Further, the secure element performs 96-bit subsequent function calculation on the decrypted random number, and sends the calculation result to the card reading device through the near field communication controller. The card reading device performs 96-bit subsequent function operation on the card reading random number, and the obtained result is compared with the calculated result to determine whether to disable or disable

In step S807, the secure element triggers a false departure operation.
