RESIST SRP AGAINST WORMHOLE ATTACK
Marjan Kuchaki Rafsanjani, Mahmoud Eshraghi Samani · 2013
Ad-hoc networks refer to temporary or interim networks which form for special purposes. Actually they are wireless networks with mobile nodes. These networks use no network assisting element for path routing and in these networks available nodes are responsible for path routing. Therefore when malicious nodes want to find a way to interfere with the path routing then the existence of a secure route protocol (SRP) can prevent the interference. SRP protocol is one of the secure algorithms of path routing protocol but it is not resistant against wormhole attack. Wormhole attack is considered as a subtle attack in which two malicious nodes make a short connection in network's topology through private or implicit connection and represent two non neighbor nodes as neighbors and prevent the correct operation of path routing protocol by using this method. One of the methods of preventing wormhole attack is by using packet leashes. We try to decrease the wormhole attack occurrence in this routing protocol by a kind of packet leashes called temporal leashes. We also will minimize problems resulting from using temporal leashes by different methods and modifications in its structure.
