Security Aspects of Inter-Vehicle Communications

Jean-Pierre Hubaux, Maxime Raya

Inter-Vehicular Communications (IVC) are a cornerstone of the future intelligent transportation systems. A crucial enabling component of IVC is its security and privacy. Indeed, as vehicular computing systems become interconnected, there will be new venues ...

Secure positioning of wireless devices with application to sensor networks

Jean-Pierre Hubaux, Srdan Capkun

So far, the problem of positioning in wireless networks has been mainly studied in a non-adversarial setting. In this work, we analyze the resistance of positioning techniques to position and distance spoofing attacks. We propose a mechanism for secure pos ...

The Security of Vehicular Ad Hoc Networks

Jean-Pierre Hubaux, Maxime Raya

Vehicular networks are likely to become the most relevant form of mobile ad hoc networks. In this paper, we address the security of these networks. We provide a detailed threat analysis and devise an appropriate security architecture. We also describe some ...

A Family of Fast Syndrome Based Cryptographic Hash Functions

Recently, some collisions have been exposed for a variety of cryptographic hash functions including some of the most widely used today. Many other hash functions using similar constructions can however still be considered secure. Nevertheless, this has dra ...

DICTATE: DIstributed CerTification Authority with probabilisTic frEshness for Ad Hoc Networks

Jean-Pierre Hubaux, Jun Luo, Patrick Eugster

Securing ad hoc networks is notoriously challenging, notably due to the lack of an on-line infrastructure. In particular, key management is a problem that has been addressed by many researchers but with limited results. In this paper, we consider the case ...

Broad New OS Research: Challenges and Opportunities

James Richard Larus

Contemporary software systems are beset by problems that create challenges and opportunities for broad new OS research. To illustrate, we describe five areas where broad OS research could significantly improve the current user experience. These areas are d ...

Location verification and key management in wireless networks

Srdan Capkun

This thesis is primarily concerned with two security mechanisms for wireless networks: location verification and key management. These mechanisms are potential building blocks in the security architectures of a range of applications. Under location verific ...

Mobility Helps Security in Ad Hoc Networks

Jean-Pierre Hubaux, Levente Buttyan, Srdan Capkun

Contrary to the common belief that mobility makes security more difficult to achieve, we show that node mobility can, in fact, be useful to provide security in ad hoc networks. We propose a technique in which security associations between nodes are establi ...

Optimal location of FACTS devices to enhance power system security

Stéphane Gerbex

This paper compares three heuristic methods (SA, TS and GA) applied to the optimal location of FACTS devices in a power system. The optimizations are made on three parameters: the location of the devices, their types and their sizes. The FACTS devices are ...
