Abstract
A routing protocol is used to transmit messages from a sender to a receiver over a network of nodes, where adversaries can control links between the nodes and can also control the behavior of a large number of nodes. Various techniques can be used, along or in combination, to combat these effects. In one approach, certain trigger conditions are identified, the occurrence of which signals malicious behavior within the network. When signaled, the sender requests status reports from the intermediate nodes in an effort to determine which nodes are malicious. The information for the status reports is generated by nodes as packets are passed from one node to the next.
