and setting a digital key authentication algorithm in the third-party application, receiving a challenge value sent by a digital key system, performing symmetric key calculation on the challenge value, and returning a corresponding authentication value to the digital key system for authentication.
8. A contactless automobile key implementation device, comprising:
the key generation unit is used for acquiring a key state, setting a key of the vehicle key equipment aiming at the third-party application in the initial identification state based on a preset local digital key learning process;
and the operation unit is used for setting a digital key authentication algorithm in the third-party application, receiving the challenge value sent by the digital key system, carrying out symmetric key calculation on the challenge value, and returning a corresponding authentication value to the digital key system for authentication.
9. An electronic device, comprising:
a processor; and
a memory for storing a program of the contactless car key implementation method, wherein the electronic device executes the contactless car key implementation method according to any one of claims 1 to 5 or 7 after being powered on and running the program of the contactless car key implementation method through the processor.
