| Outline of Final Research Achievements |
In recent years, mobile ad hoc networks(MANET) are becoming more and more important when it is hard to use normal network infrastructures. However, the open nature of the wireless communication makes them vulnerable to various security attacks. Wormhole attack is one of the most serious attacks on MANET. By employing out of band link called as ‘wormhole,' attacker provides routing path and takes illegal actions such as data corruption and eavesdropping over communications.
In this study, I have proposed a set of countermeasures, which include multiple routing path generation, incoherency detection in propagation delay, and authentication of the acknowledgment, to the wormhole attack on MANET. The proposed method is confirmed by network simulation and implementation to wireless nodes which have limited computational power.
