<p>A user authentication method, apparatus and system for passive optical network. The method comprises: Optical Line Terminal OLT receives an user authenticating request from Optical Network Unit ONU, the authenticating request bringing a cryptographic identification; said OLT performs authentication according to the user cryptographic identification sent by said ONU, and then opens or closes a path from the ONU to a network side according to the authentication result. A passive optical network and an Optical Line Terminal OLT are also provided. The user authentication method provided by the present invention can enable the passive optical network user management and administration to be easier and more convenient, and improve the terminal interchangeability and the user security. Further, after the user changes the ONU, the new ONU also can access the network using the cryptographic identification.</p> |
