METHOD AND APPARATUS FOR AUTHENTICATION IN PASSIVE OPTICAL NETWORK AND PASSIVE OPTICAL NETWORK THEREOF

摘要

The embodiments of the present invention provide a method and an apparatus for authentication in a Passive Optical Network (PON), and a PON. The method includes: receiving, by an Optical Network Unit /Optical Network Terminal (ONU/ONT), a first negotiation message sent by an Optical Line Terminal (OLT), and authenticating the OLT according to a logic registration ID of the OLT; sending, by the ONU/ONT, a second negotiation message to the OLT, the logic registration ID of the ONU/ONT is used to enable the OLT to authenticate the ONU/ONT according to a logic registration ID of the ONU/ONT, and allocates a terminal identifier for the ONU/ONT after the authentication succeeds. In the embodiments of the present invention, the OLT and the ONU/ONT are authenticated through the logic registration IDs, thus eliminating security threats in the authentication process.
