Compromise-Resilient Anti-Jamming Communication in Wireless Sensor Networks

Jamming is a kind of Denial-of-Service (DoS) attack in which an adversary purposefully emits radio frequency signals to corrupt the wireless transmissions among normal nodes. Although some research has been conducted on countering jamming attacks, few works consider jamming attacks launched by insiders, where 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 nodes. In this paper, the authors address the insider jamming problem in wireless sensor networks. In the proposed solutions, the physical communication channel of a sensor network is determined by the group key shared by all the sensor nodes.
