[0038] The method embodiment provided in the first embodiment of the present application can be executed in a mobile terminal, a computer terminal or a similar computing device. Figure 1 The hardware structure block diagram of a computer terminal (or mobile device) for implementing a configuration method of an electronic payment device is shown. Figure 1As shown, the computer terminal 10 (or mobile device) may include one or more (102a, 102b, ..., 102n are used to illustrate) processors 102 (the processor 102 may include but is not limited to a processing device such as a microprocessor MCU or a programmable logic device FPGA), a memory 104 for storing data, and a transmission device 106 for communication functions. In addition, it may also include: a display, an input / output interface (I / O interface), a universal serial bus (USB) port (which may be included as one of the ports of the BUS bus), a network interface, a power supply and / or a camera. It can be understood by those skilled in the art that Figure 1 The structure shown is only for illustration and does not limit the structure of the above electronic device. Figure 1 More or fewer components as shown, or with Figure 1 Different configurations shown.

[0039] It should be noted that the one or more processors 102 and / or other data processing circuits described above may generally be referred to herein as "data processing circuits". The data processing circuits may be embodied in whole or in part as software, hardware, firmware, or any other combination thereof. In addition, the data processing circuit may be a single independent processing module, or may be incorporated in whole or in part into any of the other components in the computer terminal 10 (or mobile device). As described in the embodiments of the present application, the data processing circuit acts as a processor control (e.g., selection of a variable resistor terminal path connected to an interface).

[0040] The memory 104 can be used to store software programs and modules of application software, such as program instructions / data storage devices corresponding to the configuration method of the electronic payment device in the embodiment of the present application. The processor 102 executes various functional applications and data processing by running the software programs and modules stored in the memory 104, that is, the configuration method of the electronic payment device described above is implemented. The memory 104 may include a high-speed random access memory, and may also include a non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory.

[0042] The display may be, for example, a touch screen liquid crystal display (LCD) that enables a user to interact with a user interface of the computer terminal 10 (or mobile device).

[0043] Under the above operating environment, this application provides Figure 2 The configuration method of the electronic payment device shown. Figure 2 It is a flowchart of a configuration method of an electronic payment device according to Embodiment 1 of the present application.

[0044] Step S201, obtaining a terminal number of an initial electronic payment device to be configured and determining configuration information of functions that need to be configured for the initial electronic payment device.

[0045] Optionally, the terminal number of the initial electronic payment device to be configured and the configuration information of the functions to be configured of the initial electronic payment device may be obtained through the management terminal of the initial electronic payment device.

[0046] Generally speaking, the terminal number of the initial electronic payment device is 15 digits, consisting of a 4-digit area code + a 4-digit branch number + a 4-digit merchant number + a 3-digit terminal sequence number. It should be noted that if the terminal number of the initial electronic payment device only has a 4-digit area code, it means that the QR code configuration generated subsequently is universal for all merchants under it. If the terminal number of the initial electronic payment device only has a 4-digit area code + a 4-digit branch number, it means that it is effective for merchants under a certain branch. If the terminal number of the initial electronic payment device only has a 4-digit area code + a 4-digit branch number + a 4-digit merchant number, it means that it is effective for all terminals of a specific merchant. If the terminal number of the initial electronic payment device only has a 4-digit area code + a 4-digit branch number + a 4-digit merchant number + a 3-digit terminal sequence number, it is only effective for a specific smart electronic payment device. If the terminal number is less than 15 digits, the 15 digits are supplemented by the method of post-filling F, for example, enter 9008 (area code) + 0199 (branch number) + FFFF + FFF.

[0047] In an optional embodiment, a management personnel may input the above terminal number at the management end and select the function to be configured.

[0048] In an optional embodiment, the configuration information of the function to be configured of the initial electronic payment device can be represented by 4 digits, the first three digits represent the configuration operation object, and the fourth digit represents the configuration operation action. For example, opening a communication program can be recorded as 0011, 001 represents the communication program, and 1 represents opening. The configuration information can also be closing a bank card balance query, which can be recorded as 0020, 002 represents a bank card balance query, and 0 represents closing.

[0049] Step S202, generating a target QR code according to the terminal number and configuration information.

[0050] Optionally, the management terminal of the initial electronic payment device to be configured processes the acquired terminal number and configuration information to generate a target QR code. After the target QR code is obtained, it can be sent to the relevant merchant by email or other means.

[0051] Step S203: According to the target QR code, the initial electronic payment device is functionally configured to obtain the target electronic payment device.

[0052] Optionally, after receiving the target QR code sent by the management end of the initial electronic payment device to be configured, the initial electronic payment device can obtain configuration information of the function to be configured by scanning the target QR code, and then perform corresponding function configuration to obtain the target electronic payment device.

[0053] In summary, the management end generates a target QR code based on the terminal number of the initial electronic payment device and the configuration information of the required configuration function. The initial electronic payment device obtains the configuration information by scanning the target QR code, and the corresponding function configuration of the initial electronic payment device can be realized. This avoids the manual configuration of the electronic payment device, thereby achieving the effect of improving the configuration efficiency of the electronic payment device.

[0054] Optionally, generating a target QR code based on the terminal number and configuration information includes: obtaining target password information of the management end corresponding to the initial electronic payment device; obtaining a first key based on the target password information, the terminal number and a first preset value; generating a target QR code based on the first key, the terminal number, the configuration information and the validity period of the target QR code to be generated.

[0055] In an optional embodiment, generating a target QR code through the terminal number and configuration information includes the following steps: obtaining target password information of the management terminal corresponding to the initial electronic payment device. Generally speaking, the target password information consists of 6 digits, for example, 123456.

[0056] In order to improve the security of the target QR code, a first key, for example, key A, is obtained according to the target password information, the terminal number and the first preset value. For example, the 6-digit and 15-digit terminal number of the initial electronic payment device and the first preset value 5 are spliced, and the spliced ​​characters are used as the above-mentioned first key. At the same time, in order to improve the security of the target QR code, the validity period of the target QR code can also be set. The validity period is in the YYMMDD format, which is used to identify the expiration date of the QR code, for example, 240410.

[0057] Finally, the target two-dimensional code is generated according to the first key, the terminal number, the configuration information and the validity period of the target two-dimensional code to be generated.

[0058] The first key and terminal number can add a layer of security verification to the generation of the QR code, ensuring that only specific terminals can obtain the configuration information corresponding to the target QR code. By setting the validity period of the QR code, the life cycle of the QR code can be effectively controlled, further improving data security.

[0059] Optionally, generating a target QR code based on the first key, terminal number, configuration information and the validity period of the target QR code to be generated includes: encrypting the terminal number, configuration information and the validity period of the target QR code to be generated by using the first key to obtain a first ciphertext; determining a first message authentication code based on the first ciphertext; obtaining a second key based on the target password information, the terminal number and a second preset value; encrypting the first message authentication code and target data based on the second key to obtain a second ciphertext, wherein the target data consists of the terminal number, configuration information and the validity period of the target QR code to be generated; and generating a target QR code based on the second ciphertext.

[0060] In an optional embodiment, the target QR code is generated by the following steps: First, the terminal number, configuration information and the validity period of the target QR code to be generated are encrypted by a first key to obtain a first ciphertext, for example, ciphertext A. In an optional embodiment, the encryption work can be completed by using the CBC mode (CipherBlock Chaining) encryption method of the SM4 cryptographic algorithm (symmetric encryption algorithm).

[0061] After obtaining the first ciphertext, the first message authentication code MAC is obtained according to the first ciphertext, for example, the last 4 bytes of the first ciphertext are taken as the first message authentication code. Then, the second key is obtained according to the target password information, the terminal number and the second preset value, for example, the 6-digit and 15-digit terminal number of the initial electronic payment device and the second preset value 9 are spliced, and the spliced ​​characters are used as the second key, for example, key B.

[0062] After obtaining the second key, the second key is used to encrypt the first message authentication code and terminal number, configuration information and the validity period of the target QR code to be generated to obtain a second ciphertext. In an optional embodiment, the CBC mode (Cipher Block Chaining) encryption method of the SM4 cryptographic algorithm (symmetric encryption algorithm) can be used to complete the above encryption work.

[0063] It should be noted that the target data (for example, data A) composed of the terminal number, configuration information and the validity period of the target QR code to be generated is in the form of: 15-digit terminal number|expiration date|function selection 1|function selection 2...|&&|. For example, data A is composed of 90080199FFFFFFF|240410|0011|0020|&&.

[0064] The above-mentioned first message authentication code and target data are assembled into data B, that is, data B is data A+MAC+FEFFFFFFFFFFFFFFFFFFFFFFFF, and the data B is encrypted in sm4's cbc mode using key B to obtain ciphertext B.

[0065] Finally, the second ciphertext (ie, ciphertext B) is converted into a two-dimensional code to obtain the above-mentioned target two-dimensional code.

[0066] The first message authentication code is determined by the first ciphertext, and then the first message authentication code and the target data are encrypted according to the second key, and the above-mentioned target QR code is obtained according to the final ciphertext. The double encryption method is adopted, which can effectively improve the security of the QR code.

[0067] Optionally, obtaining the first key based on the target password information, the terminal number and the first preset value includes: obtaining multiple first key factors based on the target password information and the first preset value; processing the terminal number to obtain multiple second key factors; and concatenating the multiple first key factors and the multiple second key factors to obtain the first key.

[0068] In an optional embodiment, the above-mentioned first key can be obtained by the following steps: multiplying the target password information and a first preset value (for example, 2) to obtain a calculated value, and then obtaining multiple first key factors based on the calculated value. For example, if the target password information is 123456 and the calculated value is 24690, 24690 is split into two first key factors, namely 246 and 690.

[0069] Then, the terminal number is processed, for example, digits 5 to 15 of the 15-digit terminal number are split into three second key factors, and finally the first key is obtained according to multiple first key factors and multiple second key factors. For example, the first key factor + second key factor can be directly used to obtain the first key.

[0070] In an optional embodiment, the target password information can be multiplied by the first preset value to obtain a value and then add a group of random 6-digit values, and then the last six digits of the result are taken and divided to further enhance the security of encryption. For example, (123456*2)+137596=384508, the last 6 digits are taken and then divided into two groups, 384 is the first key factor A of the first key, and 508 is the first key factor B of the first key.

[0071] In an optional embodiment, the second key factor can also be obtained in the following manner: the first four digits of the terminal number are multiplied by 5, the last 4 digits of the result are taken, and then divided into two groups, the first two digits are the second key factor C, and the last two digits are the second key factor D. For example, the first four digits of the terminal number are 9008*5+3344=48384, the last 4 digits are taken as 8384, and then divided into two groups, 83 is the second key factor C, and 84 is the second key factor D. Then, digits 5 to 8 of the terminal number are the second key factor E; digits 9 to 12 of the terminal number are the second key factor F; and digits 13 to 15 of the terminal number are the second key factor G.

[0072] Finally, a 32-bit first key is obtained by concatenating multiple first key factors and multiple second key factors. For example, the first key is composed of EEEEEEEE+second key factor G+first key factor A+second key factor F+first key factor B+second key factor E+second key factor C+second key factor D+EEE.

[0073] In an optional embodiment, the second key can be obtained in the following manner: first, the 6-digit password is *3 and the last 6 digits are taken out, that is, (123456*3)+248653=619021, and the last 6 digits are taken out, and then divided into two groups, 619 is the key factor A, and 021 is the key factor B. The first four digits of the terminal number 12 are input 9008*7+1357=64413, and the last 4 digits are taken out to be 4413, and then divided into two groups, 44 is the key factor C, and 13 is the key factor D. Then, the 32-bit key B is concatenated, which is composed of AAAAAAAA+key factor C+FFF key factor B+FFF+key factor A+key factor D+AAAAAAAA.

[0074] By calculating and dividing the target password information, terminal number and the first preset value, multiple key factors are obtained, and then the key factors are spliced, which improves the security of the first key, thereby achieving the technical effect of improving the security of the target QR code.

[0075] Optionally, based on the target QR code, the initial electronic payment device is functionally configured to obtain the target electronic payment device, including: obtaining target password information of the management end corresponding to the initial electronic payment device; decrypting the data corresponding to the target QR code based on the target password information and the terminal number to obtain decrypted configuration information; and functionally configuring the initial electronic payment device based on the decrypted configuration information to obtain the target electronic payment device.

[0076] In an optional embodiment, according to the target QR code, the functional configuration of the initial electronic payment device includes the following steps: the initial electronic payment device obtains the target password information of the management end corresponding to the initial electronic payment device. It should be noted that the target password information can be informed by the management personnel.

[0077] The data corresponding to the target QR code is decrypted using the target password information and the terminal number to obtain the decrypted configuration information. Finally, the initial electronic payment device is functionally configured according to the decrypted configuration information to obtain the target electronic payment device.

[0078] By decrypting the target password information, terminal number and target QR code, the automatic configuration of the initial electronic payment device is realized, which improves the efficiency of function configuration.

[0079] Optionally, the data corresponding to the target QR code is decrypted based on the target password information and the terminal number to obtain the decrypted configuration information, including: obtaining a second key based on the target password information, the terminal number and the second preset value; decrypting the data corresponding to the target QR code based on the second key to obtain decrypted target data and a decrypted message authentication code; verifying the decrypted message authentication code to obtain a verification result; when the verification result indicates that the verification is passed, obtaining the decrypted configuration information based on the decrypted target data.

[0080] In an optional embodiment, the above-mentioned decrypted configuration information can be obtained by the following steps: Generate a second key according to the target password information, the terminal number and the second preset value. For example, the value obtained by multiplying the target password information by the second preset value is taken to obtain the last six digits, and divided into two groups as part of the first key. Furthermore, the value obtained by multiplying the target password information by the first preset value can also be added to a group of random 6-digit values, and then the last six digits of the result are taken to further enhance the security of encryption. For example, (123456*3)+248653=619021, take the last 6 digits, and then divide them into two groups, 619 is the first key factor A, and 021 is the first key factor B.

[0081] Then, the first four digits of the terminal number are multiplied by 7, and the last four digits are taken, and then divided into two groups, the first two digits are the second key factor C, and the last two digits are the second key factor D. For example, the first four digits of the terminal number of the electronic payment device are 9008*7+1357=64413, and the last four digits are taken as 4413, and then divided into two groups, 44 is the second key factor C, and 13 is the second key factor D. Finally, AAAAAAAA+second key factor C+FFF first key factor B+FFF+first key factor A+second key factor D+AAAAAAAA is used as the above-mentioned second key.

[0082] The data corresponding to the target QR code is decrypted by the second key. The data corresponding to the target QR code is ciphertext B. The data obtained by decrypting ciphertext B by the second key is data B, which is data A+MAC+FEFFFFFFFFFFFFFFFFFFFFFFFF. Removing the last 24 bits of data B gives data A+MAC. The decrypted message authentication code needs to be verified, and if the verification is passed, the last 4 bits of data A+MAC are taken as MAC, and then the remaining data is separated by |. The first group is the 15-digit terminal number. Remove the F after the terminal number. If the remaining string is the same as the string of the local terminal number, it means that it is valid for the terminal, otherwise it is rejected. The second group is a 6-digit validity period. If it is within the validity period, continue. The third to the second to last group are the decrypted configuration information. For example, data A is 90080199FFFFFFF|240410|0011|0020|&&FFFFFFFFFFFFFFFFFFFFFFFFFFFFF, then the corresponding configuration information is |0011|0020|.

[0083] The above steps can effectively prevent illegal access and data leakage, while ensuring the authenticity and integrity of the configuration information, thereby improving the security of remote configuration of electronic payment devices.

[0084] Optionally, the decrypted message authentication code is verified to obtain a verification result including: obtaining a first key based on the target password information, the terminal number and the first preset value; encrypting the decrypted target data with the first key to obtain a third ciphertext; determining a second message authentication code based on the third ciphertext; and verifying the decrypted message authentication code based on the second message authentication code to obtain a verification result.

[0085] In an optional embodiment, the decrypted message authentication code is verified by the following steps: a first key is obtained according to the target password information, the terminal number and the first preset value. For example, the target password information and the first preset value (for example, 2) are multiplied to obtain a calculated value, and then multiple first key factors are obtained according to the calculated value. For example, if the target password information is 123456 and the calculated value is 24690, 24690 is split into two first key factors, 246 and 690 respectively. Then, the terminal number is processed, for example, digits 5 to 15 of the 15-digit terminal number are split into 3 second key factors, and finally the first key is obtained according to multiple first key factors and multiple second key factors. For example, the first key factor + second key factor can be directly used to obtain the first key.

[0086] The first key can also be obtained by the following steps: after the 6-digit password is *2, the last 2 digits are taken out, that is, (123456*2)+137596=384508, the last 6 digits are taken out, and then divided into two groups, 384 is the first key factor A, and 508 is the first key factor B. The first four digits of the terminal number are 9008*5+3344=48384, and the last 4 digits are taken out to be 8384, which are then divided into two groups, 83 is the second key factor C, and 84 is the second key factor D. The 5th to 8th digits of the terminal number are the key factor E; the 9th to 12th digits of the terminal number are the key factor F; the 13th to 15th digits of the terminal number are the key factor G, and then the 32-bit first key is concatenated, which is composed of EEEEEEEE+second key factor G+first key factor A+second key factor F+first key factor B+

[0087] The second key factor E+the second key factor C+the second key factor D+EEE.

[0088] Then, the decrypted target data is encrypted with the first key to obtain the third ciphertext, that is, the data A is decrypted in sm4 cbc mode with the first key to obtain ciphertext A, and then the last 4 bytes of ciphertext A are taken as MAC. Then the decrypted message authentication code is compared to see if it is the same as the MAC in data B. If they are the same, the verification of the decrypted message authentication code is passed.

[0089] By verifying the message authentication code, it can be effectively ensured that the data has not been tampered with during the transmission process, thereby improving the security of the remote configuration of the electronic payment device.

[0090] In an optional embodiment, the following steps can be used to verify the validity period of the QR code. Before the initial electronic device processes the QR code, the initial electronic payment device signs in the acquiring system. The acquiring system determines the sign-in message sent by the initial electronic payment device, returns a successful response message after confirmation, and then obtains the date in the response message. It should be noted that the sign-in message may include an area code for comparison with the area code in the terminal number obtained after decryption of the target QR code. The date entered in the response message is in the YYMMDD format, for example, 240408. The date obtained from this sign-in is used to compare with the validity period of the QR code. The validity period can only be continued if it is greater than the date obtained from this sign-in. For example, if the validity period (240410) is greater than the date (240408) obtained from this sign-in, then continue.

[0091] In an optional embodiment, the following may be used: Figure 3 The flowchart shown realizes the generation of the QR code, which specifically includes:

[0092] Step 1: The management end of the initial electronic payment device to be configured signs in to the acquiring system. After returning a successful response message, the management end obtains the configuration information of the function to be configured and obtains the target password information;

[0093] Step 2: Calculate, split and concatenate the target password information, the terminal number and the first preset value to generate a first key, encrypt the terminal number, the configuration information and the validity period of the target QR code to be generated by the first key to obtain a first ciphertext, and take the last 4 bytes of the first ciphertext as the first message verification code;

[0094] Step 3: Calculate, split and concatenate the target password information, the terminal number and the second preset value to generate a second key, and encrypt the first message authentication code and the target data using the second key to obtain a second ciphertext;

[0095] Step 4: Convert the second ciphertext into a target QR code and send it to the relevant merchant via a messaging program or email.

[0096] In an optional embodiment, the following may be used: Figure 4 The flowchart shown implements the functional configuration of the initial electronic payment device, specifically including:

[0097] Step 1: The initial electronic payment device to be configured signs in at the acquiring system. After returning a successful response message, the sign-in date in the response message is obtained;

[0098] Step 2: Enter the target password information sent by the acquirer administrator to the merchant, and scan the target QR code to convert it into the second ciphertext;

[0099] Step 3: Calculate, split and concatenate the target password information, the terminal number and the second preset value to generate a second key, decrypt the second ciphertext using the second key to obtain the decrypted target data and the decrypted message verification code;

[0100] Step 4: Obtain a first key from the target password information, the terminal number and the first preset value, encrypt the decrypted target data with the first key to obtain a third ciphertext, and take the last 4 bytes of the third ciphertext as the second message verification code;

[0101] Step 5: The second message authentication code verifies the decrypted message authentication code to obtain a verification result. When the verification result indicates that the verification is passed, the decrypted configuration information is obtained from the decrypted target data.

[0102] Step 6: The electronic payment device updates its configuration according to the configuration information to obtain the target electronic payment device.

[0103] In an alternative embodiment, the Figure 5 The configuration system shown implements the configuration of the smart POS machine, such as Figure 5 As shown, the configuration system includes smart POS acquiring management APP1, merchant smart POS acquiring APP2, and acquiring system 3. Among them, smart POS acquiring management APP1 is used to generate a configuration QR code; merchant smart POS acquiring APP2 is used to scan the configuration QR code to update the local configuration; acquiring system 3 is used to provide the merchant smart POS acquiring APP2 with a check-in and return date.

[0104] In an optional embodiment, the execution process of the smart POS acquiring management APP1 is as follows: Figure 6 As shown, it includes: and function selection, terminal number input, validity period input, target password information input, MAC generation, ciphertext B generation and QR code generation.

[0105] In an optional embodiment, the execution process of the merchant smart POS acquiring APP2 is as follows: Figure 7 As shown, it includes: signing in and obtaining the date, inputting the target password information, scanning the QR code, decrypting the ciphertext, verifying the MAC and updating the configuration.

[0106] In an optional embodiment, the execution process of the acquiring system 3 is as follows: Figure 8 As shown, it includes: receiving a sign-in request message, verifying a message, and sending a sign-in response.

[0107] The configuration method of the electronic payment device provided in the embodiment of the present application encrypts and generates a target QR code through the terminal number of the initial electronic payment device to be configured and the configuration information of the functions that need to be configured of the initial electronic payment device, and performs functional configuration on the initial electronic payment device based on the target QR code to obtain the target electronic payment device, thereby solving the technical problem of needing to manually configure the functions of the electronic payment device, resulting in relatively low configuration efficiency.

[0108] In this solution, the terminal number of the initial electronic payment device and the configuration information of the required configuration function are input into the management terminal corresponding to the initial electronic payment device to be configured, and the target QR code is generated by encrypting the terminal number and the configuration information. Then, the target QR code is scanned by the initial electronic payment device, and the data corresponding to the target QR code is decrypted to obtain the configuration information, and the corresponding function configuration is performed on the initial electronic payment device, thereby obtaining the target electronic payment device. Through this solution, the remote configuration of the electronic payment device is realized, avoiding the need for the acquiring business personnel to go to the specific merchant site to configure the new function of the electronic payment device, thereby achieving the effect of improving the configuration efficiency of the electronic payment device.
