ABSTRACT
Networks of wireless sensors present a cost-effective solution to a range of applications in critical domains such as detection of chemical or biological agents or tracking of enemy vehicles. In these critical applications, using incorrect or maliciously corrupted data can have disastrous consequences. Security services are essential to ensure the authenticity, confidentiality, freshness, and integrity of the critical information collected and processed by such networks. This seminar critically examines key-management services that enable a sensor network to set up cryptographic keys in an autonomous fashion, without relying on expensive cryptography or trusted servers, and with minimal administrative overhead.
