Embodiment 1

[0055] Embodiment 1: ONU activation process for centralized transmission of authentication information

[0056] In this embodiment, the ONU authentication information is sent collectively during the ONU device activation process, such as figure 1 As shown, the key steps include:

[0057] Step 101: OLT sends a device authentication request to ONU;

[0058] Step 102: The ONU sends the device identification (including the serial number and RegID) and the encrypted user identification to the OLT;

[0059] Step 103: The OLT authenticates the device identification and the encrypted user identification sent by the ONU, and the authentication succeeds in step 104; otherwise, the ONU activation process is terminated and further interaction with the ONU is stopped.

[0060] In order to realize the authentication of the device ID and the encrypted user ID, the present invention adds two modules to the OLT, which are the device ID authentication unit for device ID authentication and the encrypted u...

Embodiment 2

[0071] Embodiment 2: ONU activation process for distributed authentication information

[0072] In this embodiment, the authentication information of the ONU is distributed and sent during the ONU activation process, such as image 3 As shown, the key steps include:

[0073] Step 301: The OLT sends a device authentication request;

[0074] Step 302: The ONU sends a device identification to the OLT, and the device identification is a serial number or RegID;

[0075] Step 303: The OLT invokes the device identification authentication unit to determine whether the device identification (serial number or RegID) is legal, if it is legal, go to step 304; otherwise, terminate the ONU activation process and stop further interaction with the ONU;

[0076] Step 304: The OLT allocates an ONU-ID to the ONU according to the legal ONU device identification (serial number or RegID);

[0077] Step 305: The OLT sends a ranging request to the ONU to perform ranging;

[0078] Step 306: The ONU sends the enc...

Abstract

The invention discloses an optical network unit (ONU) activating method and system in a gigabit passive optical network (GPON) system, aiming at solving the technical problems that uplink authentication information is wiretapped and the resource of the GPON system is occupied by a maliciously-registered illegal ONU when the ONU is activated. In order to guarantee the authenticating security of ONU equipment, the invention previously distributes a user identifier and a user secret key for an optical line terminal (OLT) and the ONU, wherein the OLT locally memorizes the corresponding relationship among an equipment identifier, the user identifier and the user secret key; the ONU offers the equipment identifier and the encrypted user identifier to the OLT when the ONU is activated; and the OLT obtains the user secret key and the user identifier which correspond to the ONU and are locally memorized by the equipment identifier to authenticate the ONU equipment for the encrypted user identifier. The invention can prevent the resource of the GPON system from being occupied and consumed when an illegal ONU is activated, and can prevent the authentication process of the ONU from being wiretapped and counterfeited by a malicious user, thereby guaranteeing the authenticating security of the ONU equipment.

Description

Technical field [0001] The invention relates to the field of GPON (Gigabit Passive Optical Network, gigabit passive optical network), and more specifically, to an ONU activation method and system in a GPON system. Background technique [0002] GPON system generally consists of OLT (Optical Line Terminal), ONU (Optical Network Unit, Optical Network Unit) and ODN (Optical Distribution Network). ODN is a point-to-multipoint structure, and one OLT is connected through ODN Multiple ONUs. [0003] In the GPON system, in order to prevent illegal ONUs from accessing the OLT, the OLT generally needs to authenticate the ONU. The authentication of the ONU by the OLT is based on the SN (Serial Number) or the RegID (Registration ID) of the ONU. The OLT authenticates the ONU at the later stage of the ONU activation process. The ONU activation process mainly includes the following steps: [0004] Step 1. The ONU listens to the downstream GTC (GPON Transmission Convergence, GPON Transmission Conv...
