Improving the ID-Based Key Exchange Protocol in Wireless Mobile Ad Hoc Networks

摘要

In 2005, Liaw et al. proposed an ID-based key exchange protocol without the auxiliary of certification authority that can be applied to wireless mobile Ad hoc networks, which can solve the security problem in the Wireless Mobile Ad hoc Networks (MANET) and is suitable for other wired network structures. Liaw et al.'s protocol, however, still has other serious weaknesses. The current paper will demonstrate the vulnerability of the protocol. Furthermore, we present a method that can avoid attacks.
