Abstract
The present disclosure relates to a device authentication method and system, an IoT device, and an authentication server. The method includes: obtaining random data; obtaining public input parameters including the random data, and generating an authentication proof based on a preset proof parameter and the public input parameters; sending the authentication proof to an authentication server, such that the authentication server verifies the authentication proof based on a preset verification parameter to obtain an authentication result; obtaining the authentication result returned by the authentication server. This embodiment can use authentication proof without the need to use device key information for authentication, improving authentication security. Moreover, the authentication server is unable to restore device key information based on the authentication proof, further avoiding leakage of the device key information and improving information security.
