SECURITY DATA TRANSMISSION METHOD IN ETHERNET(R) PASSIVE OPTICAL SUBSCRIBER NETWORK SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a security data transmission method in an Ethernet(R) passive optical subscriber network system. SOLUTION: The method is composed of: a step of generating a transmission frame including a data field for encrypting security data, a key information field for storing key information to be used for restoring the encrypted data in the data field, and a security frame equipped with optical subscriber network unit (ONU) ID field indicating optical subscriber network unit information for an optical subscriber network unit (ONU) to identify a destination user and a user ID field indicating a security ID to be identified by the destination user, and a step of transmitting the generated transmission frame.
