Abstract
Official abstract text for this publication.
Disclosed is a method of registering only an authorized optical network terminal among a plurality of optical network terminals with the same serial number, in an optical line terminal, using a public key encryption algorithm, in a Gigabit Passive Optical Network (GPON). According to an exemplary aspect, a GPON system encrypts a physical layer OAM message transmitted/received for serial number registration of an optical network terminal, using a key distributed according to a public key encryption algorithm, and authenticates registration of the optical network terminal using the encrypted physical layer OAM message. Accordingly, it is possible to securely authenticate registration of an authorized optical network terminal and block registration of unauthorized optical network terminals.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method in which an optical network terminal obtains a registration approval from an optical line terminal in a Gigabit passive optical network (GPON), comprising: at the optical network terminal, being assigned an optical line terminal (OLT) public key, by the optical line terminal, when the optical network terminal joins the GPON, the OLT public key corresponding to an optical line terminal (OLT) private key assigned to the optical line terminal; an…
