Broadcast Authentication and Key Management for Secure Sensor Networks
Peng Ning, Donggang Liu · 2005
This chapter is intended as a starting point for studying sensor network security. It focuses on recent advances in broadcast authentication and key management in sensor networks, which are foundational cryptographic services for sensor network security. Authors describe µTESLA and multi-level µTESLA protocols developed for scalable broadcast authentication in sensor networks. They then describe random key pre-distribution techniques proposed for establishing pairwise keys between resource constrained sensor nodes. Attacks against location discovery and some additional security problems in sensor networks are then discussed.
