In spite of several years of intense research, the area of security and cryptography in Wireless Sensor Networks (WSNs) still has a number of open problems. On the other hand, the advent of Identity-Based Encryption (IBE) has enabled a wide range of new cryptographic solutions. In this work, we argue that IBE is ideal for WSNs and vice versa. We discuss the synergy between the systems, describe how WSNs can take advantage of IBE, and present results for computation of the Tate pairing over resource constrained nodes. keywords: identity-based encryption, bilinear pairings, key management, sensor networks
