文摘A new group key management scheme against the unreliable wireless communication channel and unsafe environment was proposed for wireless sensor network(WSN).In the proposed scheme,broadcast polynomial, generated over finite field F_q based on the secret sharing,was employed to revoke compromised sensor nodes.In order to tolerate key-update message loss,group session keys were generated as one-way hash chain sequence and distributed in advance.The analysis showes that the scheme has better performance in terms of the computation and communication overhead.
