Key establishment in sensor networks is a challenging problem because of resource constraints of the sensors. The classical public-key routines are impractical in most sensor network architectures. In this paper, the authors propose a new random key pre-distribution scheme which is based on the identity-based approach for key establishment between two neighbor nodes in wireless sensor networks. Their proposed scheme provides better security against node capture, in particular, against node fabrication attack than the existing random key pre-distribution schemes.
