In wireless sensor networks,the most energy-consuming operation is the communication among network nodes.The energy consumed in communication is much less than that in computation.The broadcasting is one of the most energy-saving forms in communication because of the communication modes of One-To-Many and Many-To-One.To assure the validity of the entity and the privacy of the message,we should firstly solve the problem of the broadcast key secure distribution.Motivated by these concerns,on the enough consideration on the characteristics of wireless sensor networks,a broadcast key secure distri-bution protocol is proposed,in which Shamir's threshold secret sharing scheme and the ellipse curve bilinear pair are adopted.Then,security analysis and performance analysis are made on it.Analyses show that this protocol can be used to guarantee the security of wireless sensor networks,and at the same time,it can meet the special application requirements of wireless sensor networks.
