Authentication method, medium, and electronic device

An authentication method, comprising:

• receiving, by a second device, a first authentication request from a first device, wherein the first authentication request is sent by the first device in response to a distance between the second device and the first device reaching a first preset distance;
• determining, by the second device in response to the received first authentication request, whether wireless communication between the second device and the first device is subject to a relay attack according to a duration of an anti-relay determination exceeding a time threshold, wherein the anti-relay determination comprises simultaneously performing satellite positioning and network positioning to determine a height and position of the second device and further comprises determining, in a trusted execution environment (TEE), whether the second device is rooted, wherein the second device being rooted comprises the second device being subject to malicious control;
• and
• sending, by the second device, a first authentication success ciphertext to the first device in response to determining that wireless communication between the second device and the first device is not subject to the relay attack, wherein the first authentication success ciphertext is associated with performance, by the first device, of a service agreed on between the first device and the second device.

A first device, comprising:

• one or more processors;
• and
• at least one non-transitory memory;
• and
• at least one non-transitory computer readable memory connected to the one or more processors and including computer program code, wherein the at least one non-transitory computer readable memory and the computer program code are configured, with the one or more processors, to cause the first device to perform at least:
• sending, in response to determining that a distance between the first device and a second device reaches a first preset distance, a first authentication request to the second device, wherein the first authentication request requests that the second device determine whether wireless communication between the first device and the second device is subject to a relay attack according to a duration of an anti-relay determination exceeding a time threshold and before the first device performs a service agreed on with the second device, wherein the anti-relay determination comprises simultaneously performing satellite positioning and network positioning to determine a height and position of the second device and further comprises determining, in a trusted execution environment (TEE), whether the second device is rooted, wherein the second device being rooted comprises the second device being subject to malicious control;
• determining in response to determining that the distance between the first device and the second device reaches a second preset distance, whether a first authentication success ciphertext sent by the second device is received, wherein the first authentication success ciphertext is sent by the second device in response to the second device determining that wireless communication between the first device and the second device is not subject to the relay attack, and further in response to the second preset distance being less than the first preset distance;
• and
• performing the service agreed on with the second device in response to the first device determining that the first authentication success ciphertext sent by the second device is received, and further in response to verification performed by the first device on the first authentication success ciphertext succeeding.
