Title: Design of privacy mechanisms for wireless sensor networks with intrusion detection



 

Abstract: Wireless sensor networks often have to be protected not only against an active attacker who tries to disrupt network operations, but also against a passive attacker looking for some sensitive information like the location of a certain node or information about the movement of a tracked object. To address such issues, we can use an intrusion detection system and a privacy mechanism simultaneously. However, both of these often come with contradictory aims. A privacy mechanism typically tries to hide a relation between various events while an intrusion detection system tries to link the events up.

This talk will present and explore some of the problems that might occur when such techniques are brought together and we also provide some ideas how these problems could be solved. Other related work on simulations (of wireless sensor networks), experiments with evolutionary algorithms for protocol design, and our attempts to provide a semi-automated framework that optimizes the configuration of an intrusion detection system in terms of detection accuracy and memory usage shall be also mentioned.
