BRIEF DESCRIPTION OF THE DRAWINGS

[0043] Figure 1 It is a flow chart of the method for secondary issuance of ETC electronic tags provided by an embodiment of the present invention;

[0044] Figure 2 It is a structural diagram of the ETC electronic tag secondary issuance system provided by an embodiment of the present invention. DETAILED DESCRIPTION

[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] The terms "first", "second", etc. in the specification and claims of the present invention are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the terms used in this way are interchangeable under appropriate circumstances, so that the embodiments of the present invention can be implemented in an order other than those illustrated or described herein. In addition, the term "and / or" in the specification and claims means at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0047] The following, in conjunction with the accompanying drawings, describes in detail the ETC electronic tag secondary issuance method provided by the embodiment of the present invention through specific embodiments and their application scenarios.

[0048] See also Figure 1 , Figure 1 : is a flow chart of the ETC electronic tag secondary issuance method provided by an embodiment of the present invention. The ETC electronic tag secondary issuance method provided by this embodiment includes the following steps:

[0049] S110, when the issuing device is in a preset state, the server sends a first encryption and decryption certificate to the issuing device.

[0050] The ETC electronic tag secondary issuance method in this embodiment is applied to the ETC electronic tag secondary issuance system, which includes a server, an issuance device and an ETC electronic tag, wherein the issuance device can be a mobile terminal, the ETC electronic tag can be an ETC user card, and the issuance device and the ETC electronic tag are connected through a vehicle bus subsystem.

[0051] Here, it needs to be clarified that the existing ETC electronic tag secondary issuance method mainly includes two ways to realize the communication between the issuing device and the ETC electronic tag.

[0052] One is that the issuing device and the ETC electronic tag use short-range communication. This issuance method requires users to be at a fixed issuance outlet or installation service outlet, with professional service personnel to perform secondary issuance operations.

[0053] Another way is that the issuing device and the ETC electronic tag communicate via Bluetooth. This issuance method requires adding Bluetooth function to the ETC electronic tag, which increases the cost of the ETC electronic tag.

[0054] Both of the above methods require manual acquisition of vehicle-related information, including vehicle model, license plate and vehicle logo, to ensure that the personalized data written into the ETC electronic tag during the secondary issuance process is consistent with the actual vehicle corresponding to the ETC electronic tag.

[0055] In this embodiment, the communication between the issuing device and the ETC electronic tag can be realized by using the vehicle bus subsystem. As an optional method, the vehicle bus subsystem is set to the OBD bus. Since the OBD bus is a bus system configured by the vehicle itself, it saves costs and does not require manual acquisition of relevant information about the vehicle. The ETC electronic tag and the issuing device are connected using the existing vehicle bus subsystem on the vehicle, which reduces the cost of the ETC electronic tag and further enhances the reliability of data transmission during the secondary issuance process.

[0056] Furthermore, in this embodiment, the vehicle bus subsystem provides an underlying data link to support data transmission, which may be a K line, a CAN line or Ethernet. In this embodiment, it mainly provides a physical layer communication link and an underlying data transmission link.

[0057] In this embodiment, the issuing device also pre-stores a second encryption and decryption certificate. Specifically, the first encryption and decryption certificate and the second encryption and decryption certificate of this embodiment can both be security certificates, which can encrypt or decrypt relevant information. The following is an explanation of the technical solution based on the first and second encryption and decryption certificates being security certificates. The preset state means that the second encryption and decryption certificate of the issuing device is verified to be legal by the server and communicates with the ETC electronic tag through the vehicle bus subsystem.

[0058] It should be understood that the server stores the issuance information corresponding to the vehicle where the ETC electronic tag is located after the secondary issuance. The above issuance information can be understood as the personalized information and vehicle information of the user corresponding to the ETC electronic tag.

[0059] When the issuing device is in a preset state, the server sends a security certificate to the issuing device.

[0060] S120, the issuing device sends the first encryption and decryption certificate to the ETC electronic tag through the vehicle bus subsystem.

[0061] In this embodiment, after receiving the security certificate, the issuing device sends the security certificate to the vehicle bus subsystem, and the vehicle bus subsystem then sends the security certificate to the ETC electronic tag. After receiving the security certificate, the ETC installs it, and the communication security of the ETC electronic tag after the secondary issuance process and the secondary issuance is guaranteed by installing the security certificate. The vehicle bus subsystem is also called the OBD bus. Since the OBD bus is a bus system configured by the vehicle itself, there is no need to manually obtain relevant information about the vehicle, so the OBD bus is set to communicate between the issuing device and the ETC electronic tag.

[0062] S130, the vehicle bus subsystem sends the pre-stored first encrypted information to the ETC electronic tag.

[0063] In this embodiment, the vehicle bus subsystem pre-stores the first encrypted information, and the first encrypted information may be the encrypted issuance information. An optional implementation is that the vehicle bus subsystem sends the first encrypted information to the ETC electronic tag; another optional implementation is that the ETC electronic tag obtains the first encrypted information stored by the vehicle bus subsystem.

[0064] S140: The ETC electronic tag is verified using the first encryption information and the first encryption and decryption certificate.

[0065] S150, when the verification is passed, the ETC electronic tag writes the issuance information, activates the ETC electronic tag, and completes the secondary issuance.

[0066] After obtaining the first encrypted information, the ETC electronic tag uses the first encrypted information and the security certificate for verification. If the verification passes, indicating that the security certificate is legal and available, the ETC electronic tag writes the issuance information, activates the ETC electronic tag, and completes the secondary issuance.

[0067] It should be noted that after the security certificate is verified, the issuing device will synchronously send the issuing information required for the secondary issuance to the server storage, thereby completing the secondary issuance activation process, and the ETC electronic tag starts working. Among them, the following embodiments use the issuing information as vehicle information as an example. Furthermore, in other embodiments, the issuing information may also include personalized information, specifically, the personalized information may be user information and contract signing information, etc.

[0068] In the embodiment of the present invention, when the issuing device is in a preset state, the server sends the first encryption and decryption certificate to the issuing device; the issuing device sends the first encryption and decryption certificate to the ETC electronic tag through the vehicle bus subsystem; the vehicle bus subsystem sends the pre-stored first encrypted information to the ETC electronic tag, and the first encrypted information is the encrypted issuance information; the ETC electronic tag uses the first encrypted information and the first encryption and decryption certificate for verification; if the verification is passed, the ETC electronic tag writes the issuance information, activates the ETC electronic tag, and completes the secondary issuance of information. In this embodiment, when the first encryption and decryption certificate is verified, a unified encryption and decryption certificate management is provided for the secondary issuance of the ETC electronic tag to ensure the security of the secondary issuance of the ETC electronic tag. In addition, after the secondary issuance of the ETC electronic tag, because the encryption and decryption certificate is installed, it is ensured that the communication process is carried out in ciphertext, which facilitates the ETC electronic tag to use the encryption and decryption certificate to communicate with other terminals of the ETC system in ciphertext, thereby improving the data security of the interaction process.

[0069] Further, the ETC electronic tag uses the first encrypted information and the first encryption and decryption certificate for verification, including:

[0070] When the ETC electronic tag does not store the issuance information, the issuing device sends the issuance information to the ETC electronic tag; the ETC electronic tag encrypts the issuance information using the first encryption and decryption certificate to obtain second encrypted information; when the first encrypted information is consistent with the second encrypted information, it is determined that the verification is successful.

[0071] A specific embodiment is that the ETC electronic tag does not store the issuance information. In this case, the ETC electronic tag obtains the issuance information from the issuing device, encrypts the issuance information using the security certificate issued by the server, and obtains the second encrypted information. Verify whether the first encrypted information is consistent with the second encrypted information. If the first encrypted information is consistent with the second encrypted information, determine that the security certificate is legal.

[0072] It should be noted that if the security certificate is not legal, then the second encrypted information encrypted using the security certificate is inconsistent with the first encrypted information.

[0073] In this embodiment, the ETC electronic tag uses a security certificate to encrypt the issuance information sent by the issuing device to obtain the second encrypted information, and by comparing the first encrypted information and the second encrypted information, ensure the legitimacy of the security certificate and the legitimacy of the one-to-one correspondence between the vehicle and the ETC electronic tag. In the subsequent work of the ETC electronic tag, the first encrypted information will be read from time to time through the vehicle bus subsystem to perform a one-to-one legitimacy check between the vehicle and the ETC electronic tag. This embodiment uses a security certificate, and the communication process uses encrypted information communication to ensure that the encryption certificate is issued, updated, and activated during and after the secondary issuance process, which can facilitate the unified management of security certificates by automobile companies.

[0074] Furthermore, the issuing device sending the issuing information to the ETC electronic tag includes:

[0075] The issuing device reads the first encrypted information pre-stored in the vehicle bus subsystem; specifically, the issuing device uses the pre-stored second encryption and decryption certificate to decrypt the first encrypted information to obtain the issuing information required for the secondary issuance; the issuing device sends the issuing information to the ETC electronic tag. In other embodiments, the issuing device can also obtain the issuing information required for the secondary issuance by automatically collecting and entering.

[0076] In this embodiment, the vehicle bus subsystem pre-stores the first encrypted information, and the issuing device obtains the first encrypted information from the vehicle bus subsystem. It should be noted that the issuing device pre-stores the security certificate. In this way, the issuing device uses the pre-stored security certificate to decrypt the first encrypted information to obtain the issuing information, and then sends the issuing information to the ETC electronic tag to further verify the security certificate in the ETC electronic tag.

[0077] Furthermore, the ETC electronic tag uses the first encrypted information and the first encryption and decryption certificate for verification, and further includes:

[0078] When the ETC electronic tag stores issuance information, the ETC electronic tag uses the first encryption and decryption certificate to decrypt the first encrypted information to obtain the decrypted first encrypted information; when the decrypted first encrypted information is consistent with the issuance information stored in the ETC electronic tag, it is determined that the verification is successful.

[0079] In a specific embodiment, the ETC electronic tag stores the issuance information. In this case, the ETC electronic tag can directly use the security certificate to decrypt the first encrypted information obtained from the vehicle bus subsystem to obtain the decrypted first encrypted information. It is verified whether the decrypted first encrypted information is consistent with the pre-stored issuance information. If the decrypted first encrypted information is consistent with the pre-stored issuance information, it is determined that the security certificate is legal.

[0080] It should be noted that if the security certificate is not legal, then the first encrypted information decrypted using the security certificate is inconsistent with the pre-stored issuance information.

[0081] In this embodiment, the ETC electronic tag uses the security certificate to decrypt the first encrypted information sent by the vehicle bus subsystem to obtain the decrypted first encrypted information, and ensures the legitimacy of the security certificate by comparing the decrypted first encrypted information with the pre-stored issuance information.

[0082] Specifically, in this embodiment, an example is given in which the first encrypted information is the first ciphertext vehicle information, the issued information is the plaintext vehicle information, and the second encrypted information is the second ciphertext vehicle information.

[0083] When the ETC electronic tag does not store plaintext vehicle information, the issuing device obtains the first ciphertext vehicle information through the on-board bus subsystem, decrypts the first ciphertext vehicle information through the security certificate of the issuing device to obtain the plaintext vehicle information, and then sends the plaintext vehicle information to the ETC electronic tag; the ETC electronic tag uses the installed security certificate to encrypt the received plaintext vehicle information to obtain the second ciphertext vehicle information; the ETC electronic tag compares the first ciphertext vehicle information with the second ciphertext vehicle information, and when it is consistent, it indicates that the data consistency is confirmed and the verification has passed, proving the reliability and correct installation of the security certificate, and simultaneously stores and locks the plaintext vehicle information in the ETC electronic tag, and at the same time, the ciphertext vehicle is synchronized to the server database through the secondary issuance device for storage and locking, indicating that the ETC electronic tag has been activated successfully and the secondary issuance is completed.

[0084] When the ETC electronic tag stores plaintext vehicle information, the ETC electronic tag can directly use the security certificate to decrypt the first ciphertext vehicle information obtained from the on-board bus subsystem to obtain the decrypted first ciphertext vehicle information. Verify whether the decrypted first ciphertext vehicle information is consistent with the pre-stored plaintext vehicle information. When the decrypted first ciphertext vehicle information is consistent with the pre-stored plaintext vehicle information, the security certificate is determined to be legal. It is further explained that the decrypted first ciphertext vehicle information can be understood as the second plaintext vehicle information, which means that when the second plaintext vehicle information is consistent with the pre-stored plaintext vehicle information, the security certificate is determined to be legal.

[0085] In this embodiment, the ETC electronic tag ensures the legitimacy of the security certificate and the legitimacy of the one-to-one correspondence between the vehicle and the ETC electronic tag by comparing the second plaintext vehicle information with the pre-stored plaintext vehicle information. In the subsequent operation of the ETC electronic tag, the first encrypted information will be read from time to time through the vehicle bus subsystem to perform a one-to-one legitimacy check between the vehicle and the ETC electronic tag.

[0086] This embodiment uses a security certificate, and the communication process uses encrypted information communication to ensure that the encrypted certificate is issued, updated, and activated during and after the secondary issuance process, which can facilitate the unified management of security certificates by automobile companies.

[0087] Furthermore, the method further comprises:

[0088] The issuing device sends a verification instruction to the server; the server reads the second encryption and decryption certificate pre-stored in the issuing device according to the verification instruction; when the second encryption and decryption certificate pre-stored in the issuing device is consistent with the encryption and decryption certificate pre-stored in the server, the server determines that the issuing device is in a preset state.

[0089] Before the secondary issuance of ETC electronic tags, it is necessary to verify whether the issuing device is in the preset state, that is, to verify whether the issuing device is in a legal state. If the issuing device is in a legal state, it means that the issuing device can participate in the secondary issuance process of ETC electronic tags.

[0090] The specific verification method is:

[0091] Since the issuing device and the server both store security certificates in advance, the status of the issuing device can be determined by verifying whether the security certificates of the two are consistent.

[0092] Specifically, the issuing device sends a verification instruction to the server. After receiving the verification instruction, the server obtains the security certificate stored in the issuing device and verifies whether the security certificate stored in the issuing device is consistent with the security certificate stored in the server.

[0093] If they are consistent, it means that the issuing device is legal and the ETC electronic tag can be issued for the second time; if they are inconsistent, it means that the issuing device is illegal and it is prohibited from participating in the secondary issuance of the ETC electronic tag.

[0094] This embodiment ensures the security of the secondary issuance process of the ETC electronic tag by verifying the status of the issuing device.

[0095] Furthermore, before the server sends the first encryption and decryption certificate to the issuing device, the method further includes:

[0096] The issuing device sends an issuing instruction to the server, so that the server sends a first encryption and decryption certificate.

[0097] After the issuing device communicates with the ETC electronic tag through the OBD bus, it sends an issuing instruction to the server.

[0098] An optional implementation is that after receiving the issuance instruction, the server sends the security certificate to the issuing device, and the issuing device then sends the security certificate to the ETC electronic tag via the OBD bus.

[0099] Another optional implementation is that after receiving the issuance instruction, the server sends a corresponding instruction to the issuing device, so that the issuing device sends the security certificate to the ETC electronic tag through the OBD bus.

[0100] In this way, during the secondary issuance process of the ETC electronic tag, the server will issue a security certificate to the ETC electronic tag, thereby ensuring the security of the secondary issuance process of the ETC electronic tag.

[0101] like Figure 2 As shown, the ETC electronic tag secondary issuance system 200 includes: a server 210, an issuance device 220, a vehicle bus subsystem 230 and an ETC electronic tag 240;

[0102] The server 210 is used to send the first encryption and decryption certificate to the issuing device when the issuing device 220 is in a preset state; the server 210 is specifically an ETC secondary issuance database, which stores user personalized secondary issuance information and installs legal security certificates.

[0103] The issuing device 220 is used to send the first encryption and decryption certificate to the ETC electronic tag 240 through the vehicle bus subsystem 230; specifically, the issuing device 220 is an ETC secondary issuing device with a network communication function, which can communicate with the server to complete data exchange, and can communicate with the ETC electronic tag through the vehicle bus subsystem 230. The issuing device 220 can be a vehicle-mounted vehicle system with the same function or an independent product device. The issuing device 220 also has the function of authenticating the security certificate issued by the server 210.

[0104] The vehicle bus subsystem 230 is used to send the pre-stored first encrypted information to the ETC electronic tag 240; the vehicle bus subsystem 230 provides an underlying data link to support data transmission, which can be a K line, a CAN line or Ethernet. In this system, it mainly provides a physical layer communication link and an underlying data transmission link.

[0105] The ETC electronic tag 240 is used to perform verification using the first encrypted information and the first encryption and decryption certificate; if the verification is successful, the issuance information is written, the ETC electronic tag is activated, and the secondary issuance is completed; in this embodiment, the ETC electronic tag has the ability of bus communication.

[0106] In this embodiment, the communication between the issuing device and the ETC electronic tag can be realized by using the vehicle bus subsystem. As an optional method, the vehicle bus subsystem is set to the OBD bus. Since the OBD bus is a bus system configured by the vehicle itself, it saves costs and does not require manual acquisition of relevant information of the vehicle. The vehicle bus subsystem is used to realize the secondary issuance and activation of the electronic tag based on the UDS custom diagnostic service, and the vehicle VIN identification is used to realize the one-to-one correspondence between the vehicle and the electronic tag, ensuring that the secondary issuance upload information is consistent with the actual loading information, and optimizing the secondary issuance activation process. Therefore, the OBD bus is set to communicate with the issuing device and the ETC electronic tag, so that the issuing device can send the issuance information and the first encryption and decryption certificate to the ETC electronic tag through the OBD bus.

[0107] Optionally, the issuing device 220 is further configured to send the issuing information to the ETC electronic tag 240 when the ETC electronic tag 240 does not store the issuing information;

[0108] The ETC electronic label 240 is further used to encrypt the issuance information using the first encryption and decryption certificate to obtain second encrypted information;

[0109] When the first encryption information is consistent with the second encryption information, it is determined that the verification is successful.

[0110] Optionally, the issuing device 220 reads the first encrypted information pre-stored by the vehicle bus subsystem 230;

[0111] The issuing device 220 uses the pre-stored encryption and decryption certificate to decrypt the first encrypted information to obtain the issuing information; in other embodiments, the issuing device 220 can also obtain the issuing information required for the secondary issuance by automatically collecting and entering;

[0112] The issuing device 220 sends the issuing information to the ETC electronic tag 240 .

[0113] Optionally, the ETC electronic tag 240 is further used to decrypt the first encrypted information using the first encryption and decryption certificate to obtain the decrypted first encrypted information when the ETC electronic tag 240 stores the issuance information;

[0114] When the decrypted first encrypted information is consistent with the issuance information stored in the ETC electronic tag 240, it is determined that the verification is successful.

[0115] Optionally, the issuing device 220 is further configured to send a verification instruction to the server 210;

[0116] The server 210 is further configured to read the first encryption and decryption certificate pre-stored by the issuing device 220 according to the verification instruction;

[0117] In the case where the second encryption and decryption certificate pre-stored in the issuing device 220 is consistent with the encryption and decryption certificate pre-stored in the server 210, the server 210 determines that the issuing device is in a preset state.

[0118] Optionally, the issuing device 220 is further configured to send an issuing instruction to the server 210 so that the server 210 sends the first encryption and decryption certificate.

[0119] In the present invention, the communication between the issuing device and the ETC electronic tag is realized by utilizing the vehicle bus subsystem. The issuing device sends the first encryption and decryption certificate to the ETC electronic tag through the vehicle bus subsystem. When the first encryption and decryption certificate is verified, a unified encryption and decryption certificate management is provided for the secondary issuance of the ETC electronic tag, thereby ensuring the security of the secondary issuance of the ETC electronic tag. In addition, after the secondary issuance of the ETC electronic tag, the ETC electronic tag can use the first encryption and decryption certificate to communicate with other terminals of the ETC system in a ciphertext manner, thereby improving the security of the data interaction process. The ETC electronic tag and the issuing device are connected by utilizing the existing vehicle bus subsystem on the vehicle, thereby reducing the cost of the ETC electronic tag and further enhancing the reliability of the secondary issuance process and data transmission after the secondary issuance.

[0120] The ETC electronic tag secondary issuance system in the embodiment of the present invention can be an ETC system, or a component, integrated circuit, or chip in a terminal. The system can be a mobile electronic device or a non-mobile electronic device.
