Abstract: In recent years, Path Identifiers (PID) are used as inter domain routing objects in network. However, the PIDs used in existing approaches are static, which makes it easy for attackers to launch Distributed Denial-Of Service (DDoS) flooding attacks. To address this issue, introduce a D-PID, framework that uses PIDs negotiated between neighboring domains as inter-domain routing objects. In DPID, the PID of an inter-domain path connecting two domains is kept secret and changes dynamically. Security of data which shared in network can be ensured with cryptographic techniques also. DPID mechanism with data secure provide more chance to prevent DDoS attacks in network.
Keyword: Inter-domain routing, Cryptographic techniques security, distributed denial-of-service (DDoS) attacks, Path Identifiers (PID).
