Location verification and key management in wireless networks

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 ...

Integrity (I) codes: Message Integrity Protection and Authentication over Insecure Channels

Jean-Pierre Hubaux, Srdan Capkun, Mario Cagalj

Inspired by unidirectional error detecting codes that are used in situations where only one kind of bit errors are possible (e.g., it is possible to change a bit “0” into a bit “1”, but not the contrary), we propose integrity codes (I-codes) for a radio co ...

Key Agreement in Peer-to-Peer Wireless Networks

Jean-Pierre Hubaux, Srdan Capkun, Mario Cagalj

We present a set of simple techniques for key establishment over a radio link in peer-to-peer networks. Our approach is based on the Diffie-Hellman key agreement protocol, which is known to be vulnerable to the ``man-in-the-middle" attack if the two users ...

Secure Positioning in Wireless Networks

Jean-Pierre Hubaux, Srdan Capkun

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

Security of Distance-Bounding: A Survey

Serge Vaudenay, Srdan Capkun, Martin Benjamin, Gildas Avoine, Aslan Tchamkerten, Ioana Cristina Carlson

Distance-bounding protocols allow a verifier to both authenticate a prover and evaluate whether the latter is located in his vicinity. These protocols are of particular interest in contactless systems, e.g. electronic payment or access control systems, whi ...

Mobility Helps Peer-to-Peer Security

Jean-Pierre Hubaux, Levente Buttyan, Srdan Capkun

We propose a straightforward technique to provide peer-to-peer security in mobile networks. We show that far from being a hurdle, mobility can be exploited to set up security associations among users. We leverage on the temporary vicinity of users, during ...

Wormhole-Based Anti-Jamming Techniques in Sensor Networks

Jean-Pierre Hubaux, Srdan Capkun, Mario Cagalj

Due to their very nature, wireless sensor networks are probably the category of wireless networks most vulnerable to “radio channel jamming”-based Denial-of-Service (DoS) attacks. An adversary can easily mask the events that the sensor network should detec ...

Secure Neighborhood Discovery: A Fundamental Element for Mobile Ad Hoc Networking

Jean-Pierre Hubaux, Panagiotis Papadimitratos, Srdan Capkun, Marcin Poturalski

Pervasive computing systems will likely be deployed in the near future, with the proliferation of wireless devices and the emergence of ad hoc networking as key enablers. Coping with mobility and the volatility of wireless communications in such systems is ...
