Abstract

Wireless Sensor Networks (WSNs) enabled with authenticated querying [1] allows only the authorized users to inject queries into the network and get responses thereof. Queries from unauthorized users are silently dropped. Providing authenticated querying for WSN is especially very challenging since the nodes are very much resource constrained and vulnerable to physical captures by the adversary. We present a fully symmetric key based solution for the above problem and analyze the same.
