Title: Compromise-Resilient Anti-Jamming for Wireless Sensor Networks

Abstract:
Jamming is a kind of Denial-of-Service (DoS) attack in which an
adversary purposefully emits radio frequency signals to corrupt
wireless transmissions.  Thus, the communications among normal sensor
nodes become difficult or even impossible. Although some research has
been conducted on countering jamming attacks, few works considered
jamming by insiders. Here, an attacker first compromises some
legitimate sensor nodes to acquire the common cryptographic
information of the sensor network and then jams the network through
those compromised sensors. In this paper, as our initial effort, we
propose a compromise-resilient anti-jamming scheme called
split-pairing scheme to deal with single insider jamming problem in a
one-hop network setting.  We implement and evaluate our solution using
the Mica2 Mote platform and show it has low recovery latency and
communication overhead, and it is a practical solution for resource
constrained sensor networks under the single insider jamming attack.
