Locating Compromised Sensor Nodes Through Incremental Hashing Authentication

Abstract. While sensor networks have recently emerged as a promising computing model, they are vulnerable to various node compromising attacks. In this paper, we propose COOL, a COmpromised nOde Locating protocol for detecting and locating compromised nodes once they misbehave in the sensor network. We exploit a proven collision-resilient incremental hashing algorithm and design secure steps to confidently locate compromised nodes. The scheme can also be combined with existing en-route false report filtering schemes to achieve both early false report dropping and accurate compromised nodes isolation.
