Method for creating digital key, device, and medium

A method for creating a digital key, performed by a target terminal, comprising:

• sending a terminal public key certificate to a target vehicle in a fleet, wherein the terminal public key certificate is obtained by signing a terminal public key of the target terminal by using a fleet pairing private key in a fleet pairing public-private key pair associated with the target vehicle;
• receiving a vehicle public key certificate sent by the target vehicle, wherein the vehicle public key certificate is sent in a case that the target vehicle performs a signature verification on the terminal public key certificate by using a fleet pairing public key in the fleet pairing public-private key pair and obtains the terminal public key after the signature verification is successful;
• and
• performing a signature verification on the vehicle public key certificate, and sending a successful signature verification notice to the target vehicle in a case that a vehicle public key of the target vehicle is obtained after the signature verification is successful.

An electronic device, comprising:

• a processor;
• and
• a memory for storing instructions executable by the processor,
• wherein the processor is configured to:
• receive a terminal public key certificate sent by a target terminal, wherein the terminal public key certificate is obtained by signing a terminal public key of the target terminal by using a fleet pairing private key in a fleet pairing public-private key pair associated with a target vehicle;
• perform a signature verification on the terminal public key certificate by using a fleet pairing public key in the fleet pairing public-private key pair;
• send a vehicle public key certificate of the target vehicle to the target terminal in a case that the terminal public key is obtained after the signature verification is successful;
• and
• determine that a digital key corresponding to the target terminal for controlling the target vehicle is successfully created in response to receiving a successful signature verification notice sent by the target terminal.
