However, a wireless sensor network is only as good as the information it produces. In this respect, the most important concern is information security. Indeed, in most application domains sensor networks will constitute a mission critical component requiring commensurate security protection. Sensor network communications must prevent disclosure and undetected modification of exchanged messages. Due to the fact that individual sensor nodes are anonymous and that communication among sensors is via wireless links, sensor networks are highly vulnerable to security attacks. If an adversary can thwart the work of the network by perturbing the information produced, stopping production, or pilfering information, then the perceived usefulness of sensor networks will be drastically curtailed. Thus, security is a major issue that must be resolved in order for the potential of wireless sensor networks to be fully exploited.

This talk is concerned with a number of novel solutions to the important problem of securing wireless sensor networks.
