The present invention relates to the field of identity authentication. Provided are a method, device, and system for identity authentication, solving the technical 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 mainly comprises: a first authenticator transmitting to a second authenticator a first identity authentication message; the second 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 on the basis of the second identity authentication message; the authentication server returning to the second authenticator a third identity authentication message; when the third identity authentication message is received by the second authenticator, same transmitting to the first authenticator a fourth identity authentication message.

Method, device, and system for identity authentication

The present invention provides an entity identification method, apparatus and system, and relates to: an entity A transmits an identification request message to an entity B, the identification request message includes the result SNof an XOR operation of a Pre-Shared Key (PSK) and the data from processing data Naccording to a first agreed rule, wherein data Nis generated by entity A, and the PSK is a key shared by A and B; entity B receives the identification request message, performs an XOR operation on SNand PSK, performs a process according to a second agreed rule, then performs a process according to a third agreed rule, and then performs an XOR operation again with the PSK processed according to the third agreed rule and then processed according to a fourth rule to obtain SON, and transmits SONthrough an identification response message to entity A.

Entity identification method, apparatus and system

A method and device device for authentication are provided. The method includes: 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.
