Abstract
An authentication apparatus for detecting and preventing a source address spoofing packet, includes a packet reception unit configured to receive a packet from a previous node or a user host; a self-assurance type ID generation unit configured to generate a self-assurance type ID of a source node of the received packet; and a self-assurance type ID verification unit configured to determine whether the source address of the received packet has been spoofed. Further, the authentication apparatus includes a white list storage unit configured to store a reliable source node; a black list storage unit configured to store an unreliable source node; and a packet transmission unit configured to transmit the packet whose source has been verified through the self-assurance type ID verification unit to a next network node.
