This disclosure provides a device identity authentication method and apparatus, an electronic device, and a computer-readable medium. The device identity authentication method includes generating, by a terminal device, a first identity authentication message in response to an identity authentication instruction; sending the first identity authentication message to the second device for the second device to authenticate an identity of the terminal device based on the first identity authentication message to obtain a first identity authentication result; receiving, by the terminal device, a second identity authentication message; wherein the second identity authentication message is a message sent by the second device when the first identity authentication result is passed; authenticating an identity of the second device based on the second identity authentication message to obtain a second identity authentication result.
