Abstract

We propose a scalable key management scheme forsensor networks consisting of a large-scale randomdeployment of commodity sensor nodes that areanonymous. The proposed scheme relies on a location-basedvirtual network infrastructure and is built upona combinatorial formulation of the group keymanagement problem. Primary features of our schemeinclude autonomously computing group keys, anddynamically computing, using a simple hash function,the mapping of nodes to group keys. The scheme scaleswell in the size of the network and supports dynamicsetup and management of arbitrary structures ofsecure group communications in large-scale wirelesssensor network.
