METHOD AND SYSTEM FOR RESILIENT PACKET TRACEBACK IN WIRELESS MESH AND SENSOR NETWORKS |
摘要 |
<p>A system and method for packet traceback in a network includes maintaining an identity number (ID) for each node in a network and generating a signature (e.g., a message authentication code (MAC)) using a secret key shared between each node on a forwarding path and a sink. Each forwarding node leaves a mark by appending its ID and a signature in the packet, either in a deterministic manner or with a probability. Upon receiving a packet at the sink, correctness of the signatures included in each packet is verified in the reverse order by which these signatures were appended. A last valid MAC is determined in the forwarding path to determine the locations of compromised nodes that collude in false data injection attacks.</p> |
