Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present application as detailed in the accompanying claims.

The background art to which the present application relates is explained first:

with the intellectualization of vehicles and the complexity of key functions of vehicles, software upgrading of keys has become a normal state. Existing key upgrade schemes typically require the owner to take the key to a special after-market maintenance point, e.g., a 4S store (Automobile Sales Service Shop), where a professional in the 4S store can upgrade the key using a special burning device.

The key is upgraded in a 4S shop, and the 4S shop can use a wired or wireless mode:

the wired upgrade mode uses special cables, even hardware clamps and special software for upgrade, and some even need to disassemble keys.

In a wireless upgrading mode, the wireless interface of the key can be used for upgrading, and the wireless interface is used for upgrading through special hardware and special software or common mobile phones and special software.

Whichever upgrade mode requires the owner to bring the key to the 4S store and requires professional personnel to operate, reducing user experience.

At the same time, because of the risk of being unreliable for operators, the security of key upgrade has a certain risk of being attacked.

Under normal conditions, the upgrading process needs to authenticate the validity of the special software, authenticate the personnel operating the professional software, and authenticate the upgrading package by the authenticated personnel operating the legal software. However, if the operator is not trusted, the user and the vehicle may not be authenticated because the authentication system is bypassed by an illegal mechanism using illegal software and dedicated upgrade software is not bound to the user or the vehicle.

Based on the above problems, the inventor of the present application found in the research process of the related technical field that, by upgrading the key by the dedicated software in the user terminal device, the terminal device performs security verification with the key by the authentication parameter distributed by the third party, i.e. the vehicle, where both the terminal device and the key are trusted before the upgrade, so that the risk caused by the unauthentication of the operator can be avoided, and the security authentication mechanism of the authentication of the third party increases the security of the key upgrade. Based on the method, the device, the equipment and the storage medium for upgrading the vehicle key are provided.

When implemented as a server, the electronic device needs to communicate wirelessly with a user's terminal device and with a vehicle.

When the electronic device is implemented as a vehicle, it is necessary to perform wireless communication with a user's terminal device, a server, and a key.

When the electronic device is implemented as a terminal device, wireless communication is required between the electronic device and a vehicle, a server, and a key.

When the electronic device is implemented as a key, wireless communication is required between the electronic device and the vehicle, the server and the terminal device.

Alternatively, the above-mentioned devices of the electronic apparatus 500 may be connected by a system bus.

The memory 512 may be a separate memory unit or may be a memory unit integrated in the processor 511. The number of processors 511 is one or more.

Optionally, the electronic device may further be provided with a display for displaying the processing result of the processor and interacting with a man-machine. In some embodiments, the display may be a front panel of the electronic device; in other embodiments, the display may be a flexible display screen, or even the display may be configured as a non-rectangular irregularly patterned display screen, i.e., a contoured screen. The display may be made of a liquid crystal display (Liquid Crystal Display, LCD), an Organic Light-Emitting Diode (OLED), or the like.

It is to be appreciated that the processor 511 may be a central processing unit (Central Processing Unit, CPU), but may also be other general purpose processors, digital signal processors (Digital Signal Processor, DSP), application specific integrated circuits (Application Specific Integrated Circuit, ASIC), etc. A general purpose processor may be a microprocessor or the processor may be any conventional processor or the like. The steps of a method disclosed in connection with the present application may be embodied directly in a hardware processor or in a combination of hardware and software modules within a processor.

The system bus may be a peripheral component interconnect standard (peripheral component interconnect, PCI) bus or an extended industry standard architecture (extended industry standard architecture, EISA) bus, among others. The system bus may be classified into an address bus, a data bus, a control bus, and the like. For ease of illustration, the figures are shown with only one bold line, but not with only one bus or one type of bus. The memory may include random access memory (random access memory, RAM) and may also include non-volatile memory (NVM), such as at least one disk memory.
