Abstract

This chapter presents the technical challenges and solutions in securing wireless networks, in particular infrastructure-less wireless networks such as mobile ad hoc networks and wireless sensor networks. Communications in infrastructure-less wireless networks are challenging, as there are no trusted base stations to coordinate the activities of mobile hosts. Applied cryptographic tools, in particular threshold cryptography, play an important role in the trust establishment, message security, and key management in such networks. We describe several technical approaches that integrate applied cryptography techniques into mobile ad hoc networks and wireless sensor networks. We also outline several research directions in these areas.
