发明名称 NETWORK AUTHENTICATION APPARATUS AND SYSTEM
摘要 <p><P>PROBLEM TO BE SOLVED: To provide a network system for rejecting an access from a terminal whose access is not permitted and from an impersonating intruder. <P>SOLUTION: Filtering sections 131 to 135 of an authentication node 100 judges whether or not a packet received via a network interface is a packet from a terminal whose access is permitted by referencing a filtering table on the basis of the MAC address and an IPv6 address and relays or discards the packet. A packet relay section 110 references an address table 160 to relay the packet passing through the filtering sections to a destination address via a proper network interface section. A filter change instruction processing section 140 receives a state change instruction for relaying the packet from a user terminal whose access is permitted and changes the filtering table of the filtering processing sections. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p>
