Problems solved by technology

[0013] In this way, illegal users may obtain the SN or MAC address of other ONUs by monitoring the PLOAM messages or MPCPDU messages of the ONU activation process, and use the SN or MAC addresses of legitimate ONUs to report to the OLT at any appropriate time. Register and complete the activation process of other ONUs, therefore, the security of the PON system cannot be guaranteed

Embodiment Construction

[0049] The core idea of ​​the present invention is that the purpose of the present invention is to provide a method, system and equipment for preventing the optical network unit in the passive optical network system from being counterfeited, through the process of allocating logical identifiers in the activation process on the ONU, the downlink The message is encrypted to prevent the ONU from being counterfeited.

[0050] The method, system and equipment of the present invention will be described in detail below in conjunction with accompanying drawings 2 to 4 .

[0051] Here, only GPON is taken as an example for description, where the equipment identifier of the ONU is usually SN, and the logical identifier of the ONU is usually ONU-ID.

[0052] Firstly, the method of the present invention is described in detail.

[0053] As shown in Figure 2, the present invention needs to pre-set the key between the OLT and the ONU, specifically, at first the OLT and a plurality of ONUs ar...

Abstract

This invention relates to a method, a system and a device for preventing imitating optical network units in a passive optical network system, in which, the method includes: A, an OLT utilizes a ciphered key to cipher the identification information of an ONU and sends a result to the ONU, B, the ONU gets the indentification information of the ONU from the result. This invented system includes: a management module of the OLT key and an authentication module of ONU, which includes a management module of ONU key and a comparison / judgement module. This invented device includes: an OLT device and an ONU device in a passive optical network.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method, system and equipment for preventing counterfeiting of optical network units in a passive optical network system. Background technique [0002] Optical access technology, especially PON (Passive Optical Network) is an important access technology in the field of access network. PON includes GPON (Gigabit Passive Optical Network) and EPON (Ethernet Passive Optical Network). [0003] As shown in Figure 1, the PON system consists of three parts: OLT (Optical Line Terminal), ODN (Optical Distribution Network) and ONU / ONT (Optical Network Unit / Optical Network Terminal). [0004] The OLT provides a network-side interface for the system and connects at least one ODN; the ODN is a passive optical splitting device, which splits and transmits the downstream data of the OLT to each ONU / ONT, and simultaneously transmits the upstream data of multiple ONUs / ONTs to the OL...
