AUTHENTICATION METHOD AND MEDIUM AND ELECTRONIC APPARATUS THEREOF

This application relates to the communications field and the artificial intelligence field, and discloses an authentication method and an electronic device. The method includes: When determining that a distance between a first device and a second device reaches a first preset distance, the first device sends a first authentication request to the second device, to request the second device to determine whether wireless communication between the first device and the second device is relayed. When determining that the distance between the first device and the second device reaches a second preset distance, the first device determines whether a first authentication success ciphertext sent by the second device is received. When the first device determines that the first authentication success ciphertext sent by the second device is received and verification performed by the first device on the first authentication success ciphertext succeeds, the first device performs a service agreed on with the second device. According to the authentication method in this application, when services such as imperceptible unlocking and imperceptible payment are performed, it can be determined whether a device that performs these services encounters a relay attack, to ensure security of the imperceptible services and make the imperceptible services more intelligent.
