A Study on Network Security Protocol to Defend against Fragmented Packet Attacks Using Biometrics

With rapid advancement of internet and web technology, damage from phishing has been increasing. To meet this issue, network authentication protocol with security implementation has been extensively studied. Single authentication such as password identification requires the authentication upon login, and session might be interrupted by ill-intentioned user once session is accomplished. Authentication method for fragmented packet is proposed to block the fragmented network attack. To prevent communication overload from the insertion of additional authentication information, the corresponding information is inserted to identifier for IP header, and packet size is controlled.
