The present invention relates to the field of identity authentication. Provided are a method, device, and system for authentication, solving the problem that existing identity authentication technologies are incapable of protecting personal privacy, and that authentication technologies comprising personal privacy must provide a traceability feature. The method for identity authentication comprises: a second authenticator transmitting to a first authenticator a first identity authentication message; the first authenticator transmitting to an authentication server a second identity authentication message; the authentication server verifying the validity of a secure domain where the second authenticator is at and of the first authenticator on the basis of the second identity authentication message; the authentication server returning to the first authenticator a third identity authentication message; the first authenticator transmitting to the second authenticator a fourth identity authentication message; the second authenticator proceeding to verification when the fourth identity authentication message is received; the second authenticator transmitting to the first authenticator a fifth identity authentication message; and the first authenticator proceeding when the fifth identity authentication message is received. The authentication system comprises the first authenticator, the second authenticator, the secure domain where the second authenticator is at, and the authentication server. |
