This work investigates how to organize access control to the WSN data in such a way that an unauthorized entity cannot make arbitrary queries to the WSN and proposes an implementation of the (cid:12)rst step of this solution.

Abstract

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 first solution to this problem and present our experiments with an implementation of the first step of this solution.

To identify denial-of-service vulnerabilities, the authors analyzed two effective sensor network protocols that did not initially consider security and demonstrate that consideration of security at design time is the best way to ensure successful network deployment.

Establishing pairwise keys in distributed sensor networks

1,361 Citations2003Donggang Liu, Peng Ning

A general framework for establishing pairwise keys between sensors on the basis of a polynomial-based key predistribution protocol is presented and a technique to reduce the computation at sensors required by these schemes is presented.

This paper introduces Sizzle, the first fully-implemented end-to-end security architecture for highly constrained embedded devices and shows that elliptic curve cryptography (ECC) not only makes public-key cryptography feasible on these devices, it allows one to create a complete secure web server stack including SSL, HTTP and user application that run efficiently within very tight resource constraints.
