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 ...

Cryptography in radio frequency identification and fair exchange protocols

Gildas Avoine

This PhD thesis focuses on fair exchange protocols and radio frequency identification protocols. Fair exchange stems from a daily life problem: how can two people exchange objects (material or immaterial) fairly, that is, without anyone being hurt in the e ...

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 ...

Reducing Fair Exchange to Atomic Commit

Rachid Guerraoui, Serge Vaudenay, Marko Vukolic, Gildas Avoine, Felix Gaertner

The fair exchange problem is key to trading electronic items in systems of mutually untrusted parties. We consider modern variants of such systems where each party is equipped with a tamper proof security module. The security modules trust each other but c ...

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 ...

Low-Power Current Mode Logic for Improved DPA-Resistance in Embedded Systems

Yusuf Leblebici, Zeynep Toprak Deniz

In this work, MOS Current Mode Logic (MCML) is analyzed for low power, low noise, mixed signal applications demanding high security such as embedded cryptographic processors and smart cards. We emphasize the possible extension of MCML gate usage for low sp ...

On the use of larger bulges in the QR algorithm

Daniel Kressner

The role of larger bulges in the QR algorithm is controversial. Large bulges are infamous for having a strong, negative influence on the convergence of the implicitly shifted QR algorithm. This paper provides a new explanation of this shift blurring effect ...

The Security and Privacy of Smart Vehicles

Jean-Pierre Hubaux, Jun Luo, Srdan Capkun

Road safety, traffic management, and driver convenience continue to improve, in large part thanks to appropriate usage of information technology. But this evolution has deep implications for security and privacy, which the research community has overlooked ...

Gracefully Degrading Fair Exchange with Security Modules

Rachid Guerraoui, Gildas Avoine

The fair exchange problem is key to trading electronic items in systems of mutually untrusted parties. In modern variants of such systems, each party is equipped with a tamper proof security module. The security modules trust each other but can only commun ...

Reproduction of security documents and color images with metallic inks

Roger Hersch, Patrick Emmel

The present invention discloses methods and systems for printing by superposing a metallic ink and transparent inks. These methods and systems are useful for color separating images into superpositions of a metallic ink and transparent inks both for design ...
