Summary

Route fingerprinting attacks target anonymous communication systems, such as Tarzan, which use peer-to-peer networks with transient nodes. The original Tarzan design had nodes learn about a random subset of other nodes, making it vulnerable to node knowledge profiling and route reconstruction attacks. An attacker can exploit the route reconstruction protocol to infiltrate the chain and compromise the entire path by causing good nodes to fail and replacing them with subverted nodes. The attacker can induce node failures through denial of service attacks or overloading the node with traffic, and then cause the replacement node to fail until a subverted node is selected. This attack can be mounted linearly from the source to the destination or vice versa.
