Abstract
Disclosed is a method and apparatus for detecting prefix hijacking attacks. A source node is separated from a destination network at a first time via an original path. The destination network is associated with a prefix. At a second time, a packet is transmitted from the source node to the destination network to determine a current path between the source node and the destination network. A packet is also transmitted from the source node to a reference node to determine a reference node path. The reference node is located along the original path and is associated with a prefix different than the prefix associated with the destination network. The current path and the reference node path are then compared, and a prefix hijacking attack is detected when the reference node path is not a sub-path of the current path.
