Secure group communication is one of the most significant requirements for different applications of a sensor network which employs a group rekeying mechanism for the secure and efficient delivery of its group data. We present a group rekeying scheme for broadcast security of a location aware wireless sensor network exploiting the polynomial share based peer to peer key establishment [3, 4, 5] technique for implementing secure channels between group nodes and then, we introduce a mechanism to deliver the group key to each sensor node.
