Since the sensor nodes join or leave the wireless sensor networks (WSNs) frequently
it is necessary to build a secure and efficient group key management system.Based on the key tree and the Chinese remainder theorem
a leveled group key management scheme is proposed.The new sensor may transmit some not sensitive messages by the sublevel group key sent to it
and a group key is sent to the new sensor so as to let it join the WSN in deed after it gets the trust of GCKS.In the leave event
the remaining nodes in the key tree are partitioned by the complete subset method.Then the group key can be updated securely by the method based on Chinese remainder theorem.Finally
we show that the proposed scheme satisfies the desired security properties
such as correctness
group key secrecy
forward secrecy and backward secrecy.The performance analysis shows that the proposed scheme is be applicable to WSNs.
