Abstract
The application discloses a user identity authentication method of a smart home device, comprising the following steps: a target application acquires first source data in response to a user triggering an identity authentication operation of a target smart home device; a SIM card of a user terminal to which the target application belongs processes the first source data to obtain a digest ciphertext of the first source data and a first signature corresponding to the digest of the first source data; a signature authentication request of the digest ciphertext and the first signature is sent to a control center server of the target application to obtain to-be-signed data, wherein the to-be-signed data is generated by the control center server based on pre-registered binding information, the digest ciphertext and the first signature after verifying that the user is legal; the to-be-signed data is signed based on the SIM card, and the signature result is sent to the control center server for signature verification to determine the access authority of the user according to the signature verification result.
