Summary:Ad hoc networks are a new wireless networking paradigm for mobile
hosts. Unlike traditional mobile wireless networks, ad hoc networks do
not rely on any fixed infrastructure. Instead, hosts rely on each other
to keep the network connected. Military tactical and other
security-sensitive operations are still the main applications of ad hoc
networks, although there is a trend to adopt ad hoc networks for
commercial uses due to their unique properties. One main challenge in
the design of these networks is their vulnerability to security attacks.
In this article, we study the threats on ad hoc network faces and the
security goals to be achieved. We identify the new challenges and
opportunities posed by this new networking environment and explore new
approaches to secure its communication. In particular, we take advantage
of the inherent redundancy in ad hoc networks-multiple routes between
nodes-to defend routing against denial-of-service attacks. We also use
replication and new cryptographic schemes, such as threshold
cryptography, to build a highly secure and highly available key
management service, which terms the core of our security framework
