The Internet consists of a large number of interconnected heterogeneous ASs (Autonomous Systems), each owned and administered by an autonomous organization. Traffic in each AS is forwarded by routers that maintain a coherent picture of the network topology using an intra-AS routing protocol. The most popular intra-AS routing protocols are link-state protocols, such as OSPF and IS-IS. An attacker who...
Modern society is becoming increasingly dependent on various communication networks such as the Internet and the sensor networks. These networks need strong security measures to keep the traffic secure. If the security fails, many aspects of the society may suffer. In this paper, we address the network security challenge by focusing on one integral part of the network functionality: routing. Using...
Detecting and handling routing loops is a critical issue in the design of anonymous peer-to-peer content sharing networks (apCSNs). A principal requirement of such a scheme is that it should not leak any message forwarding information that can undermine the user anonymity of the resulting apCSN. A number of loop handling schemes have been developed in apCSNs such as Freenet and GNUnet. However, they...
