Measuring and Analyzing on Effection of BGP Session Hijack Attack

Because there is no authentication mechanism used in BGP, a mis-behaving router can announce routes to any destination prefix on the Internet and even manipulate route attributes in the routing updates it sends to neighboring routers. Taking advantage of this weakness has become the fundamental mechanism for constructing prefix hijack attacks. The relation of network topology and prefix hijacking influence is presented for all sorts of hijacking events in different Internet layers. And a large Internet emulation environment is constructed and the attack impaction of IP prefix hijacking events are evaluated. The results that the hierarchical nature of network influences the effection of the BGP hijacking attack greatly. Key-Words: BGP hijacking; Inter-domain routing system; Internet emulation environment.
