referring to fig. 1, a general digital key system includes: a digital key terminal 1 (digital key terminal held by a vehicle owner), a vehicle machine 3, a vehicle owner device server 41, a vehicle server 42, a tracking platform 5, a friend device server 43, and a friend device 6 (digital key terminal held by a friend). The digital key terminal 1 and the car machine 3 perform identity interaction verification, which is also called key pairing or key sharing, to generate key identity creation data. The digital key terminal 1 creates data according to the key identity, and realizes the key control operation of the vehicle where the vehicle machine 3 is located.
Specifically, the digital key terminal 1 configures a near field communication module 111, a bluetooth communication module 112, and a UWB communication module 113, and the car machine 3 may configure corresponding modules that perform pairing communication with the near field communication module 111, the bluetooth communication module 112, and the UWB communication module 113.

The digital key terminal 1 performs data interaction with the owner device server 41, the friend device server 43 and the friend device 6, shares the digital key with the friend device 6, performs access configuration files which can be set by the digital key terminal 1 on the friend device 6, and terminates the shared digital key.
The friend device 6 can use the digital key shared by the digital key terminal 1, but cannot share the digital key shared by the digital key terminal 1 with other devices. The digital key terminal 1 communicates with the owner device server 41, and the friend device 6 communicates with the friend device server 43. The digital key terminal 1 and the friendly device 6 can also communicate directly with the vehicle server 42. The digital key terminal 1 and the friend device 6 can communicate with the vehicle server 42 through the owner device server 41 and the friend device server 43, respectively. The communication between the digital key terminal 1 and the owner equipment server 41 is direct, and the communication between the friend equipment 6 and the friend equipment server 43 is direct, so that service end certificates of the vehicle, the digital key terminal 1 and the friend equipment 6 are exchanged, and functions of digital key sharing, tracking, termination, notification and authentication are realized.
The owner device server 41 and the friend device server 43 are responsible for managing the life cycle (period of data) of the digital key, and renew, delete, suspend, and resume certificates in the digital key terminal 1 and the friend device 6, respectively.

Therefore, the digital key terminal 1 needs to perform identity interaction verification with the car machine 3 to generate key identity creation data, and the digital key terminal 1 needs to install and operate the digital key architecture (Digital Key Framework). The digital key terminal 1 performs data interaction with the owner device server 41, the friend device server 43, and the friend device 6, and needs to have an internet connection capability.
However, if a device such as a wristwatch or a bracelet is selected as the digital key terminal 1, the device does not have the capability to install, operate the digital key infrastructure. In order to reduce the cost, some devices such as watches or wrist rings do not have the internet connection capability.

If the first communication module 11 is the near field communication module 111 and the bluetooth communication module 112, one of them may be selected to complete the data interaction.
The digital key application module 12 includes an application protocol data unit processing sub-module 121, and when the routing target is the digital key architecture of the portable terminal, the application protocol data unit processing sub-module 121 is configured to interact with the digital key architecture (Digital Key Framework) 21 of the portable terminal 2. Wherein the interaction of the application protocol data unit comprises: the application protocol data unit processing sub-module 121 transmits the application protocol data unit to the digital key architecture 21 of the portable terminal 2, and the digital key architecture 21 of the portable terminal 2 transmits the processed application protocol data unit to the application protocol data unit processing sub-module 121.
In the embodiment of the application, the interaction of the application protocol data unit between the vehicle 3 and the digital key terminal 1 is switched to the interaction of the application protocol data unit between the vehicle 3 and the digital key architecture 21 of the portable terminal 2 through the first communication module 11 of the digital key terminal 1.

The near field communication module 111 configured in the digital key terminal 1 enables the digital key terminal 1 to interact with the vehicle machine through the near field communication module 111 and the application protocol data unit under the condition of no electricity, namely, data interaction is achieved.
According to the digital key terminal, the digital key framework is not required to be installed and operated, the digital key framework in the portable terminal connected with the digital key terminal is utilized to generate key identity creation data, the capability of installing and operating the digital key framework of the portable terminal is utilized, the selection range of the digital key terminal is enlarged, and the cost of the digital key terminal is reduced.
Embodiments of the present application are further described with a specific implementation scenario.
When the digital key terminal 1 (for example, a device such as a watch or a bracelet without the capability of installing and operating the digital key architecture) approaches the vehicle in which the vehicle machine 3 is located, the vehicle machine 3 sends an application protocol data unit to the near field communication module 111 of the digital key terminal 1, and it can be determined whether the route target is the digital key architecture 21 of the portable terminal 2 or the secure element 13 of the digital key terminal 1 according to a selection command (select command) corresponding to the application protocol data unit.
Therefore, the routing target can be determined simply through the received application protocol data unit, and the operation is simpler.
If the determined route target is the digital key architecture 21 of the portable terminal 2, the digital key terminal 1 is connected with the portable terminal 2 in a specific connection manner including: wireless or wired, the wireless mode including one of: bluetooth, internet, local area network, zigbee.
Therefore, a plurality of selectable connection modes exist between the digital key terminal 1 and the portable terminal 2 in the embodiment of the application, and the implementation of the embodiment of the application is more flexible. That is, the digital key terminal 1 and the portable terminal 2 may perform the interaction of the application protocol data unit in any of the above modes, so as to implement the scheme of the embodiment of the present application. For example, if the digital key terminal 1 itself does not have the internet connection capability, the connection to the portable terminal 2 may be implemented by a wired method or any method such as bluetooth, lan, zigbee, etc.
The application protocol data unit processing sub-module 121 included in the digital key application module 12 in the digital key terminal 1 interacts with the digital key architecture 21 of the portable terminal 2 by wire or wirelessly. The digital key architecture 21 of the portable terminal 2 processes the application protocol data unit received from the application protocol data unit processing sub-module 121 of the digital key terminal 1 in a Trusted Execution Environment (TEE), and the digital key architecture 21 of the portable terminal 2 transmits the processed application protocol data unit to the application protocol data unit processing sub-module 121. In the embodiment of the application, the identity interaction verification between the mobile phone 3 and the digital key terminal 1 is performed through the interaction of the application protocol data unit between the application protocol data unit processing sub-module 121 of the digital key terminal 1 and the digital key architecture 21 of the portable terminal 2. The application protocol data unit processing sub-module 121 of the digital key terminal 1 enables the vehicle machine 3 and the digital key architecture 21 of the portable terminal 2 to perform identity interaction verification through the near field communication module 111 of the digital key terminal 1, and the digital key architecture 21 of the portable terminal 2 generates key identity creation data.
Specifically, if the application protocol data unit processing sub-module 121 transmits the application protocol data unit to the digital key architecture 21 of the portable terminal 2 in a wired manner, the transmission of the application protocol data unit may be directly performed. If the application protocol data unit processing sub-module 121 transmits the application protocol data unit to the digital key architecture 21 of the portable terminal 2 in a wireless manner, the application protocol data unit may be packaged and then transmitted.
The digital key architecture 21 of the portable terminal 2 transmits the generated key identity creation data to the secure element 13 of the digital key terminal 1, disables (disable) the card analog function (i.e., analog IC card function) of the near field communication module 111 during the generation of the key identity creation data, and enables (enable) the card analog function of the near field communication module 111 after the generation of the key identity creation data. When the security element 13 of the digital key terminal 1 obtains the key identity creation data, it indicates that the digital key terminal 1 and the car machine 3 are paired.
When the digital key terminal 1 approaches the vehicle where the vehicle machine 3 is located again, the vehicle machine 3 sends an application protocol data unit to the near field communication module 111 of the digital key terminal 1, if the determined route target is the secure element 13, the secure element 13 interacts with the vehicle machine 3 through the near field communication module 111 by using the application protocol data unit, and the secure element 13 creates data according to the identity of the key to realize key control operation on the vehicle where the vehicle machine 3 is located.
The key control operation includes: the operations of switching on and off the lock, starting the engine, welcoming and the like are realized by the safety element according to the key identity creation data without the participation of a digital key framework.
In still another specific implementation of this embodiment of the present application, referring to fig. 3, when the route target is the server 4, the application protocol data unit processing sub-module 121 is further configured to interact with the server 4 through the digital key architecture 21 of the portable terminal 2.
In this embodiment, when the vehicle machine needs to be connected to the server 4, that is, when the route target is the server 4, the application protocol data unit processing sub-module 12 of the digital key terminal 1 performs interaction of the application protocol data unit with the server 4 through the digital key architecture 21 connected to the portable terminal 2. Therefore, in the embodiment of the present application, the digital key terminal 1 only needs to be connected to the digital key architecture 21 of the portable terminal 2, and the digital key terminal 1 may be connected to the portable terminal 2 by a wired manner, or any manner such as internet, bluetooth, local area network, zigbee, etc. The digital key terminal 1 in this embodiment of the present application does not have to have an internet connection capability, and it may be a wired mode, or any mode such as bluetooth, lan, zigbee, etc. may be used to implement the digital key architecture 21 for connecting the portable terminal 2.
Specifically, the server 4 includes: a vehicle owner device server 41, a vehicle server 42, and a friend device server 43. The functions implemented by the owner device server 41, the vehicle server 42, and the friend device server 43 are not different from those of the prior art, and will not be described in detail herein.
In still another specific implementation of the embodiment of the present application, the server 4 further includes: the Application protocol data unit processing sub-module 12 of the digital key terminal 1 performs Application protocol data unit interaction with other Application servers (not shown in the figure) through the digital key architecture 21 of the connected portable terminal 2, thereby multiplexing the upper layer Application (APP) of the portable terminal 2.
Referring to fig. 4, still another embodiment of the present application provides a digital key terminal 1, and the first communication module 11 is a bluetooth communication module 112.
The digital key terminal 1 further includes:
the second communication module 14, the second communication module 14 is used for measuring the distance between the digital key terminal 1 and the vehicle where the car set 3 is located through UWB.
The digital key application module 12 further includes: UWB coverage unit 122, UWB coverage unit 122 is configured to generate a distance instruction according to a distance between digital key terminal 1 and a vehicle in which car unit 3 is located. The application protocol data unit processing sub-module 121 is further configured to determine whether to generate key identity creation data according to the distance instruction; and/or the safety element 13 is also used for determining whether to perform key control operation on the vehicle where the vehicle is located according to the distance instruction.
Embodiments of the present application are further described with a specific implementation scenario.
When the digital key terminal 1 (for example, a watch or a bracelet without the capability of installing and operating the digital key architecture) approaches the vehicle in which the vehicle machine 3 is located, the vehicle machine 3 sends an application protocol data unit to the bluetooth communication module 112 of the digital key terminal 1, and whether the route target is the digital key architecture 21 of the portable terminal 2 or the secure element 13 of the digital key terminal 1 can be determined according to the data header corresponding to the application protocol data unit.
Because equipment such as general bracelet, wrist-watch all possess bluetooth communication module, therefore this embodiment digital key terminal is more applicable to the digital key terminal that has bluetooth communication module itself.
If the determined route target is a digital key architecture, the digital key terminal 1 is connected with the portable terminal 2, and specific connection modes include: wireless or wired, the wireless mode including one of: bluetooth, internet, local area network, zigbee.
Therefore, a plurality of selectable connection modes exist between the digital key terminal 1 and the portable terminal 2 in the embodiment of the application, and the implementation of the embodiment of the application is more flexible.
Since the bluetooth communication module 112 is provided in the embodiment of the present application, the connection between the digital key terminal 1 and the portable terminal 2 may also be implemented by selecting the bluetooth communication module 112, and no other linking manner is required.
The application protocol data unit processing sub-module 121 included in the digital key application module 12 in the digital key terminal 1 interacts with the digital key architecture 21 of the portable terminal 2 through the bluetooth communication module 112. The digital key architecture 21 of the portable terminal 2 processes the application protocol data unit received from the application protocol data unit processing sub-module 121 of the digital key terminal 1 in a Trusted Execution Environment (TEE), and the digital key architecture 21 of the portable terminal 2 transmits the processed application protocol data unit to the application protocol data unit processing sub-module 121. In the embodiment of the application, the identity interaction verification between the mobile phone 3 and the digital key terminal 1 is performed through the interaction of the application protocol data unit between the application protocol data unit processing sub-module 121 of the digital key terminal 1 and the digital key architecture 21 of the portable terminal 2. The application protocol data unit processing sub-module 121 of the digital key terminal 1 enables the vehicle machine 3 and the digital key architecture 21 of the portable terminal 2 to perform identity interaction verification through the bluetooth communication module 112 of the digital key terminal 1, and the digital key architecture 21 of the portable terminal 2 generates key identity creation data.
Specifically, if the application protocol data unit processing sub-module 121 transmits the application protocol data unit to the digital key architecture 21 of the portable terminal 2 through the bluetooth communication module 112, the application protocol data unit may be packaged and then transmitted through the bluetooth communication module 112.
Specifically, the UWB coverage unit 122 determines whether the distance between the digital key terminal 1 and the vehicle in which the car machine 3 is located, obtained by the second communication module 14, is smaller than a preset distance threshold, and generates a distance instruction if it is smaller than the preset distance threshold, otherwise, does not generate a distance instruction. The preset distance threshold is set by one skilled in the art as desired.
If the distance instruction is received, the application protocol data unit processing sub-module 121 notifies the digital key architecture 21 of the portable terminal 2 to generate key identity creation data, and the digital key terminal 1 and the vehicle 3 complete pairing; if the distance instruction is not received, the application protocol data unit processing sub-module 121 notifies the digital key architecture 21 of the portable terminal 2 that the key identification creation data is not generated, and the digital key terminal 1 and the car set 3 are not paired any more.
When the digital key terminal 1 approaches the vehicle where the vehicle machine 3 is located again, the vehicle machine 3 sends an application protocol data unit to the bluetooth communication module 112 of the digital key terminal 1, and if the security element 13 receives a distance instruction sent by the UWB coverage area unit 122, the security element 13 interacts with the vehicle machine 3 through the bluetooth communication module 112 to implement key control operation on the vehicle where the vehicle machine 3 is located according to the key identity creation data.
