Mobile Ad hoc Networks (MANET) are vulnerable to both active and passive attacks. The wormhole attack is one of the most severe security attacks in wireless ad hoc networks, an attack that can be mounted on a wide range of wireless network protocols without compromising any cryptographic quantity or network node. In Wormhole attacks, one malicious node tunnels packets from its location to the ...
A number of protocols have been proposed to date to defend against wormhole attacks in wireless networks by adopting synchronized clocks, positioning devices, or directional antennas. In this work, we introduce a novel approach for detecting wormhole attacks. The proposed algorithm is completely localized and works by looking for simple evidence that no attack is taking place, using only connec...
Wormhole attack is a severe threat against ubiquitous sensor networks. It can be launched without compromising any legitimate node or cryptographic mechanisms, and often serves as a stepping stone for many serious attacks. Most existing countermeasures often make critical assumptions or require specialized hardware devices in the network. Those assumptions and requirements limit the applicabili...
