Research on Group Key Management Framework for Wireless Sensor Networks
Juan Luo · Computer Engineering and Applications Journal · 2006
Many emerging Wireless Sensor Networks applications especial for emergency and military situations depend upon secure group communications.But group key management in WSN faces a great challenge because of badness environment,node invalidation,unreliable links and multi-hop communications.Since a distributed key generation algorithms is proposed in this paper.Furthermore a novel partial key verification strategy is raised in terms of WSN's node invalidation and unreliable links,which improved the security and validity.Simulation results demonstrate that the latter's performance is better than the former algorithm.
