Description

Technical Field

[0001] The present invention relates to the technical field of vehicles, and in particular to a safe vehicle emergency unlocking system. Background Art

[0002] In order to prevent problems such as vehicle loss and loan default, it is often necessary to use vehicle locking technology, but emergency situations often occur, such as when the vehicle is in an unsafe state or some situations where unlocking is temporarily required.

[0003] Usually, temporary unlocking requires the terminal to store an emergency unlock password. When temporary unlocking is needed, the on-site personnel enter the emergency unlock password, and the terminal unlocks the device after verifying that the passwords are consistent. This solution has the risk of emergency unlock key leakage; or the background server sends the emergency unlock password to the terminal, but there are often situations such as signal blind spots where the emergency unlock password cannot be obtained in time. Summary of the invention

[0004] In order to solve the above problems, the present invention proposes a safe vehicle emergency unlocking system.

[0005] The specific plan is as follows:

[0006] A safe vehicle emergency unlocking system, comprising: an on-board terminal, a backend server, a temporary unlocking tool and a vehicle to be unlocked;

[0007] A pair of asymmetric keys is stored in the vehicle terminal, and the asymmetric keys include a terminal public key and a terminal private key;

[0008] The backend server receives and stores the unique terminal code and terminal public key of each vehicle-mounted terminal;

[0009] After receiving the terminal unique code corresponding to the vehicle to be unlocked input by the user, the temporary unlocking tool sends an emergency unlocking password request containing the terminal unique code to the backend server;

[0010] After receiving the emergency unlock password request, the backend server generates the unlock validity time based on the request reception time, and generates the emergency unlock password for unlocking the vehicle to be unlocked, and then generates the emergency unlock password based on the unlock validity time, the emergency unlock password and the terminal unique code in the request, and searches for the corresponding terminal public key through the terminal unique code in the request, encrypts the generated emergency unlock password based on the found terminal public key, and sends it to the temporary unlock tool;

[0011] After receiving the encrypted emergency unlocking password, the temporary unlocking tool sends it to the vehicle terminal of the vehicle to be unlocked;

[0012] After the vehicle-mounted terminal decrypts the received emergency unlock password using the terminal private key, it extracts the terminal unique code and unlock validity time for verification. After the verification passes, the emergency unlock password is sent to the vehicle to be unlocked to unlock the vehicle to be unlocked.

[0013] Furthermore, the temporary unlocking tool establishes a connection with the backend server via a two-way encrypted link.

[0014] Furthermore, the two-way encrypted link adopts TLS two-way encrypted link.

[0015] Furthermore, the temporary unlocking tool communicates with the backend server wirelessly.

[0016] Furthermore, the temporary unlocking tool can communicate with the vehicle-mounted terminal via wired or wireless means.

[0017] Furthermore, the vehicle-mounted terminal adopts a terminal with a hardware encryption chip.

[0018] Furthermore, the vehicle-mounted terminal adopts asymmetric key encryption technology.

[0019] Furthermore, the vehicle-mounted terminal adopts TBOX.

[0020] Furthermore, the vehicle-mounted terminal adopts a driving recorder.

[0021] Furthermore, the vehicle-mounted terminal adopts a security gateway.

[0022] Furthermore, the terminal unique code is an international mobile equipment identity code, an integrated circuit card identification code or a serial number.

[0023] The present invention adopts the above technical solution, by encrypting the emergency unlock password, and the secret key is protected by a hardware encryption chip, which effectively prevents the problem of password leakage. At the same time, it solves the problem that the vehicle terminal cannot obtain the emergency unlock password from the background server in time when the mobile phone signal on the vehicle is weak or the signal is in a blind spot. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Figure 1 Shown is a schematic diagram of the structure of the system according to an embodiment of the present invention. DETAILED DESCRIPTION

[0025] To further illustrate various embodiments, the present invention provides drawings. These drawings are part of the disclosure of the present invention, which are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, ordinary technicians in this field should be able to understand other possible implementations and advantages of the present invention.

[0026] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0027] Embodiment 1:

[0028] The embodiment of the present invention provides a safe vehicle emergency unlocking system. Figure 1 As shown, it includes: a vehicle-mounted terminal, a background server and a temporary unlocking tool.

[0029] The vehicle terminal uses a terminal with a hardware encryption chip, including but not limited to TBOX (Telematics BOX), driving recorder, security gateway and other terminal devices. The vehicle terminal is installed on the vehicle, and each vehicle corresponds to a vehicle terminal. The vehicle terminal stores a pair of asymmetric keys, which include the terminal public key and the terminal private key.

[0030] The backend server can be a local backend server or a cloud backend server, which is not limited here. The backend server receives and stores the terminal unique code and terminal public key of each vehicle-mounted terminal. When storing, the terminal unique code and the terminal public key need to correspond one to one. The terminal unique code can be the International Mobile Equipment Identity (IMEI), the Integrated Circuit Card Identity (ICCID), the Serial Number (SN), etc.

[0031] The temporary unlocking tool can be a handheld terminal such as an electronic watch, a mobile phone, etc. for easy use. After receiving the terminal unique code corresponding to the vehicle to be unlocked input by the user, the temporary unlocking tool sends an emergency unlocking password request containing the terminal unique code to the background server. In this embodiment, the temporary unlocking tool can communicate with the background server wirelessly, and further, can establish a connection with the background server through a two-way encrypted link, including but not limited to a TLS (Secure Transport Layer Protocol) two-way encrypted link.

[0032] After the background server receives the emergency unlock password request, it generates an unlock validity period based on the request reception time (such as within 5 days from the request reception time), and generates an emergency unlock password for unlocking the vehicle to be unlocked. Then, it generates an emergency unlock password based on the unlock validity period, the emergency unlock password and the terminal unique code in the request, and searches for the corresponding terminal public key through the terminal unique code in the request. After encrypting the generated emergency unlock password based on the found terminal public key, the encrypted emergency unlock password is sent to the temporary unlocking tool.

[0033] After receiving the encrypted emergency unlocking code, the temporary unlocking tool sends it to the vehicle terminal of the vehicle to be unlocked. The temporary unlocking tool can communicate with the vehicle terminal via wired or wireless means.

[0034] After the vehicle-mounted terminal decrypts the received emergency unlock password using the terminal private key, it extracts the terminal unique code and unlock validity time for verification. After the verification passes, the emergency unlock password is sent to the vehicle to be unlocked to unlock the vehicle to be unlocked.

[0035] After the vehicle to be unlocked receives the emergency unlocking password, the vehicle is unlocked within the unlocking validity time based on the emergency unlocking password therein.

[0036] The embodiment of the present invention proposes a safe vehicle emergency unlocking system consisting of a vehicle-mounted terminal with a hardware encryption chip, a background server, and a temporary unlocking tool, which effectively avoids the leakage of encryption keys and improves security, effectiveness and convenience.

[0037] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, it should be understood by those skilled in the art that various changes may be made to the present invention in form and details without departing from the spirit and scope of the present invention as defined by the appended claims, all of which are within the scope of protection of the present invention.
