Abstract

Wireless Sensor Networks (WSNs) have enabled applications in which security properties are of paramount importance. Security, in turn, is frequently bootstrapped through key distribution schemes. Most of the key distribution techniques, however, are ill-suited to WSNs. This makes extremely hard and challenging the objective of securing WSNs. In this work, we aimed at proposing key distribution schemes that are both (i) lightweight and (ii) able to fulfill architecture-specific needs. To our knowledge, ours is the first work in performing authenticated key distribution in WSNs in a non-interactive way through the use of Pairing-Based Cryptography.
