Abstract: A method and a related device for unlocking a smart lock are provided, and may be applied to an intelligent vehicle or a self-driving vehicle, to implement an unlocking function of a smart lock of the vehicle. The method includes: A terminal device monitors a distance change trend between the terminal device and an intelligent device, where the intelligent device includes a smart lock. If the terminal device determines that the terminal device is approaching the intelligent device and a distance between the terminal device and the intelligent device is less than a first distance threshold, the terminal device enables an identity authentication process between the terminal device and the intelligent device. The terminal device unlocks the smart lock when identity authentication between the terminal device and the intelligent device succeeds.

Abstract: A first apparatus sends a first random number to a second apparatus, where a vehicle carries the first apparatus and a first set. The second apparatus belongs to the first set. The first set further includes a third apparatus. The first apparatus communicates with the third apparatus using the second apparatus. The first apparatus receives a first message from the second apparatus. The first message includes first verification information to perform identity verification on the second apparatus. The first verification information is based on identity information of the second apparatus and the first random number. The first apparatus determines, based on the first verification information and the first random number, that the identity verification on the second apparatus has succeeded.
