Authentication method and equipment, electronic equipment and storage medium

Abstract

The embodiments of the invention relate to the field of authentication, and disclose an authentication method and equipment, electronic equipment and a storage medium. In the authentication method andequipment, the electronic equipment and the storage medium, the authentication method includes the steps that a first distance is acquired, and the first distance is a distance between first equipment and equipment which directly transmits a first authentication request to the first equipment, wherein the first authentication request is originally generated and sent by second equipment; a seconddistance is acquired, and the second distance is a distance between the second equipment and equipment which directly transmits a second authentication request to the second equipment, wherein the second authentication request is originally generated and sent by the first equipment; and according to the first distance and the second distance, whether the authentication is successful or not is determined. Bidirectional positioning is carried out through the first equipment and the second equipment, the first distance is compared with the second distance, according to the comparison result, whether the authentication is successful or not is determined, the security of the first equipment is ensured, and the relay attack is effectively prevented.

Description

technical field [0001] The embodiments of the present invention relate to the field of authentication, and in particular to an authentication method, authentication equipment, electronic equipment, and storage media. Background technique [0002] In recent years, a keyless entry and start (Passive Entry Passive Start, PEPS) system has been widely used. The PEPS system means that when the distance between the key carried by the user and the vehicle meets the preset distance, the vehicle will be automatically unlocked without the user actively performing an unlocking operation. [0003] The inventors have found at least the following problems in the prior art: the current PEPS systems on the market cannot defend against relay attacks (Relay Attacks). When a vehicle equipped with the PEPS system encounters a relay attack, any data sent by the vehicle's electronic control unit to the key will be forwarded to the key via one or more relay devices; at the same time, the data sent...

AI Technical Summary

Problems solved by technology

[0003] The inventors have found that there are at least the following problems in the prior art: the current PEPS system on the market cannot resist relay attacks (Relay Attacks)

Due to the relaying of one or more relaying devices, when the distance between the key and the vehicle is very far (exceeding the preset distance), the electronic control unit of the vehicle will receive a message sent by a relaying device that corresponds to the vehicle The data of the signal strength required for authentication, and then the relay device can open the door, so that the safety of the vehicle and the contents of the vehicle cannot be guaranteed
