Energy-Efficient and Scalable Group Key Management for Hierarchical Sensor Network

Key management is deemed as the fundamental essential part of any secure communication. A secure sensor network communication protocol relies on the substantial secure, robust and efficient key management system. Implementing a private and public key pair for sensor network is impractical due to high computation and energy consumption. In this paper, the authors put forward two group key management schemes for hierarchical self-organizing wireless sensor network architecture. Both of the schemes are designed in such a way that more computational and communication burden is placed on the forwarding node and the similar workload is kept as low as possible at the sensor nodes. Besides, multilevel security can be achieved to secure groups of sensors at different levels.
