the digital key scans a two-dimensional code on a physical key to obtain physical key information and first check code information; the physical key information comprises a Bluetooth address and identification code information;

the digital key generates second check code information according to the physical key information;

checking the first check code according to the second check code;

after the verification is passed, the digital key generates a first random number.

3. The method of claim 2, wherein checking the first check code according to the second check code comprises:

and judging whether the second check code is consistent with the first check code, if so, passing the check, and if not, failing to pass the check.

4. The method of claim 1, further comprising, prior to the DK-ECU generating the second random number:

and the DK-ECU receives the physical key information sent by the physical key so as to acquire corresponding second key information according to the physical key information.

5. The method of claim 1, wherein the physical key and the DK-ECU establish a bluetooth connection comprising:

the physical key sends a Bluetooth connection message to the DK-ECU by scanning the Bluetooth broadcast of the DK-ECU and enters a Bluetooth connection state;

and the DK-ECU enters a Bluetooth connection state after receiving the Bluetooth connection message and establishes Bluetooth connection with the physical key.

6. A system for activating a physical key, comprising: a digital key, a physical key and a digital key electronic control unit DK-ECU; the digital key, the physical key and the DK-ECU are connected in a Bluetooth mode;

7. An apparatus for activating a physical key, comprising:

the first key information sending module is used for sending the first key information to a physical key by the digital key to activate the physical key if the comparison result shows that the first key information is matched with the second key information;

the first key information sending module is further configured to: the physical key and the DK-ECU establish Bluetooth connection; the DK-ECU generates a second random number, generates first session key information according to the second random number and the second key information, and sends the second random number to the physical key; the physical key generates second session key information according to the second random number and the stored first key information, and sends the second session key information to the DK-ECU; and the DK-ECU compares the first session key information with the second session key information, if the first session key information is matched with the second session key information, the authentication is passed, and the authentication result is returned to the physical key.

8. An electronic device, characterized in that the electronic device comprises:

at least one processor; and

the memory stores a computer program executable by the at least one processor, the computer program being executable by the at least one processor to enable the at least one processor to perform the method of physical key activation of any one of claims 1-5.

9. A computer-readable storage medium storing computer instructions for causing a processor to perform the method of activating a physical key of any one of claims 1-5 when executed.
