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 paper, the authors argue that IBE is ideal for WSNs and vice versa. They discuss the synergy between the systems, describe how IBE can solve the key agreement problem in WSNs, and present some estimates of performance.
