AUTHENTICATION SYSTEM FOR POWER LINE COMMUNICATION AND METHOD FOR DISTRIBUTING AUTHENTICATION DATA FOR POWER LINE COMMUNICATION

摘要

PROBLEM TO BE SOLVED: To provide an authentication system for power line communication by which authentication data is distributed by excluding a risk of being eavesdropped and a method for distributing the authentication data for the power line communication.;SOLUTION: When an interface 12 constituting a local communication part of a slave side modem 1b is connected to an interface 12 constituting a local communication part of a master side modem 1a via a communication line 15, a first judgment part 10 of the master side modem 1a transmits and distributes an encryption key which is the authentication data preliminarily stored in a storage part 8 to the slave side modem 1b via the communication line 15.;COPYRIGHT: (C)2007,JPO&INPIT
