Abstract

Key management has remained a challenging issue in sensor networks due to the constraints of sensor node resources.First

a probabilistic model to analyze the security of key infection was derived.Then a group based key infection to further improve its security performance was proposed.Finally

by combining the key infection with a lightweight key pre-distribution mechanism

a more secure key distribution scheme for sensor networks

Group based Key Infection with Key Pre-distribution

was presented.Analysis results show that proposed scheme presents a viable trade-off between security and resource consumption for smart dust sensor networks.
