Abstract

This paper presents a Constrained Function based message Authentication (CFA) scheme for wireless sensor networks, which meets all the requirements of the so-called sensor authentication criteria, while most of the existing schemes only achieve partial requirements. In particular, to the best of our knowledge, CFA is the first authentication scheme supporting enroute filtering with only a single packet overhead. We examine the CFA scheme from both the theoretical and experimental aspects. Our method has also been practically implemented on the TelosB compatible mote for performance evaluation.
