Abstract:
A critical challenge faced by sensor network security provisioning is that sen
sors are susceptible to physical capture attacks. Once a sensor is compromised
, the adversary can easily launch clone attacks by replicating the compromised
node, distributing the clones throughout the network, and starting a variety
of other attacks such as insider attacks. In this talk, I will first present o
ur superimposed s-disjunct code based clone attack detection scheme, which com
putes for each sensor a social fingerprint by extracting the neighborhood char
acteristics, and verifies the legitimacy of the originator for each message by
checking the enclosed fingerprint. Then I will propose our approach to explor
ing the spatial correlation of the networking behaviors of the sensors in clos
e proximity for compromised node detection. This design is motivated by the ob
servation that neighboring sensors should behave similarly in normal condition
s. Finally I will talk about future research directions toward sensor network
security.
