Title: Filtering of Injected False Data in Sensor Networks

Abstract:
In this talk, I will present a scheme for addressing false data
injection attacks in sensor networks.  These attacks are insider
attacks, where an adversary may compromise several sensor nodes, and
then use the compromised nodes to inject false data into the network.
Standard authentication mechanisms for not sufficient to prevent such
attacks, since the adversary knows all the keying material possessed
by the compromised nodes.  This scheme detects any injected false data
packets when no more than a certain threshold of nodes are
compromised.  In addition to presenting the basic scheme, I will
discuss the security and performance properties of the scheme.
