We investigate how to organize access control to the WSN data in such a way that an unauthorized entity ( the adversary ) cannot make arbitrary queries to the WSN. We call this problem authenticated querying . Roughly, this means that whenever the sensor nodes process a query, they should be able to verify that the query comes from a legitimate user. Authenticated querying is especially challenging if the adversary can gain full control over some sensor nodes through physical access ( node capture attack). We propose (cid:12)rst so-lution to this problem and present our experiments with an implementation of the (cid:12)rst step of this solution.
