More on Castor: the Scalable Secure Routing for Ad-hoc Networks

Karl Aberer, Panagiotis Papadimitratos, Marcin Poturalski, Wojciech Galuba, Zoran Despotovic

Wireless ad hoc networks are inherently vulnerable, as any node can disrupt the communication of potentially any other node in the network. Many solutions to this problem have been proposed. In this paper, we take a fresh and comprehensive approach, simult ...

Adaptive Message Authentication for Vehicular Networks

Jean-Yves Le Boudec, Jean-Pierre Hubaux, Nikodin Ristanovic, Panagiotis Papadimitratos, Georgios Theodorakopoulos

Public key cryptography can introduce significant processing delays in vehicular communication platforms. This can lead to serious performance issues, especially in the case of multi-hop Inter-Vehicle Communication. In this paper we propose Adaptive Messag ...

Sheridan Printing2009

With a number of projects developing vehicular communication systems, there is rising awareness on threats and the need to introduce security and privacy-enhancing mechanisms. With recent results, in principle in agreement across different major projects, ...

Secure Neighbor Discovery in Wireless Networks: Formal Investigation of Possibility

Jean-Pierre Hubaux, Panagiotis Papadimitratos, Marcin Poturalski

Wireless communication enables a broad spectrum of applications, ranging from commodity to tactical systems. Neighbor discovery (ND), that is, determining which devices are within direct radio communication, is a building block of network protocols and app ...

A Low-Cost Secure Neighbor Verification Protocol for Wireless Sensor Networks

Jean-Pierre Hubaux, Panagiotis Papadimitratos, Reza Shokri, Marcin Poturalski, Gaël Ravot

Neighbor Discovery (ND) is an enabler for communication in Wireless Sensor Networks (WSN). Attacks against ND, notably the well-known and simple to mount wormhole attack, can severely degrade performance and security. Hence it should be thwarted in any WSN ...

Towards Provable Secure Neighbor Discovery in Wireless Networks

Jean-Pierre Hubaux, Panagiotis Papadimitratos, Marcin Poturalski

In wireless systems, neighbor discovery (ND) is a fundamental building block: determining which devices are within direct radio communication is an enabler for networking protocols and a wide range of applications. To thwart abuse of ND and the resultant c ...
