A Distributed Group Key Management Scheme for Sensor Networks
Liang Dai · Computer Knowledge and Technology · 2009
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 the resources are constrained.Based on the thresh-old secret sharing mechanism and group key share refresh mechanism,a distributed group key management scheme is proposed in this paper.Analysis results demonstrate that the scheme has good security performance and lower network overheads.
