ONU (Optical network unit) authentication method and ether passive optical network system

Abstract

The invention discloses an ONU (optical network unit) authentication method and an ether passive optical network (EPON) system, belonging to the technical field of ONU authentication. The ONU authentication method comprises the steps that local end equipment finds and connects with ONU equipment to be authenticated and sends an authentication request message to the ONU equipment to be authenticated; after receiving the authentication request message, the ONU equipment newly increases authentication information to the physical address information of the ONU equipment, and sends a response message carrying the physical address information and the authentication information of the ONU equipment to the local end equipment; the local end equipment carries out authentication on the physical address information and the authentication information in the responses message; and if the authentication is successful, the local end equipment sends an authentication passing message to the ONU equipment and terminates the authentication process, wherein the authentication information is invisible for users. According to the invention, the detection of the ONU legitimacy is guaranteed, and the commercial profit of operators and the information safety of users are guaranteed to the greatest extent on the basis of meeting the Chinese telecommunication EPON equipment standard.

Description

technical field [0001] The invention relates to the technical field of ONU authentication, in particular to an ONU authentication method and an Ethernet passive optical network system. Background technique [0002] According to China Telecom's EPON (Ethernet Passive Optical Network, Ethernet Passive Optical Network) standard specification, the certification of ONU (Optical Network Unit, optical node) refers to the OLT (optical line terminal, optical line terminal), that is, in the EPON system The central office device detects the ONU device according to the information of each connected ONU device to determine whether the ONU device meets the standard, so as to control the access of the ONU and ensure that the information data flow will not be stolen by the unrelated ONU device The detection method is the legality detection of the ONU. This is a way to solve the information security problem in the EPON system. [0003] For the EPON system including OLT / ONU, China Telecom's...

Problems solved by technology

However, when the network system where the user is located is FTTH and the ONU device is placed directly at the user's home, it is not very safe to use the authentication method based on the MAC address, because the MAC information of the ONU may be forcibly modified by the user, making the ONU legal. The illusion of not trying to use network resources and threatening the information security of other users
