Evaluating Resistance of MCML Technology to Power Analysis Attacks Using a Simulation-Based Methodology

Paolo Ienne, Francesco Regazzoni, Yusuf Leblebici, Zeynep Toprak Deniz

This paper explores the resistance of MOS Current Mode Logic (MCML) against attacks based on the observation of the power consumption. Circuits implemented in MCML, in fact, have unique characteristics both in terms of power consumption and the dependency ...

The Complexity of Distinguishing Distributions

Serge Vaudenay, Thomas Baignères

Cryptography often meets the problem of distinguishing distributions. In this paper we review techniques from hypothesis testing to express the advantage of the best distinguisher limited to a given number of samples. We link it with the Chernoff informati ...

GossiCrypt: Wireless Sensor Network Data Confidentiality Against Parasitic Adversaries

Jean-Pierre Hubaux, Panagiotis Papadimitratos, Jun Luo

Abstract—Resource and cost constraints remain a challenge for wireless sensor network security. In this paper, we propose a new approach to protect confidentiality against a parasitic adversary, which seeks to exploit sensor networks by obtaining measureme ...

Logical concepts in cryptography

Simon Kramer

This thesis is about a breadth-first exploration of logical concepts in cryptography and their linguistic abstraction and model-theoretic combination in a comprehensive logical system, called CPL (for Cryptographic Protocol Logic). We focus on two fundamen ...

Secure Position-Based Routing for VANETs

Panagiotis Papadimitratos, Charles Harsch

Vehicular communication (VC) systems have the potential to improve road safety and driving comfort. Nevertheless, securing the operation is a prerequisite for deployment. So far, the security of VC applications has mostly drawn the attention of research ef ...

Reducing Time Complexity in RFID Systems

Gildas Avoine, Philippe Oechslin, Etienne Dysli

Radio frequency identification systems based on low-cost computing devices is the new plaything that every company would like to adopt. Its goal can be either to improve the productivity or to strengthen the security. Specific identification protocols base ...

High Security Pairing-Based Cryptography Revisited

Robert Granger

The security and performance of pairing based cryptography has provoked a large volume of research, in part because of the exciting new cryptographic schemes that it underpins. We re-examine how one should implement pairings over ordinary elliptic curves f ...

A Protection Scheme for MoC-Enabled Smart Cards

Serge Vaudenay, Claude Barral

The concept of Match-on-Card (MoC) consists of a smart card which receives an applicant's candidate template T to be compared with the stored reference template T_ref by processing the complete matching algorithm during a biometric authentication request. ...

Practical Cryptography in High Dimensional Tori

Robert Granger, Martijn Stam

At Crypto 2004, van Dijk and Woodruff introduced a new way of using the algebraic tori

T_n

in cryptography, and obtained an asymptotically optimal

n/\phi(n)

savings in bandwidth and storage for a number of cryptographic applications. However, the compu ...

Radio Frequency Identification: Adversary Model and Attacks on Existing Protocols

Gildas Avoine

Radio Frequency Identification (RFID) systems aim to identify objects in open environments with neither physical nor visual contact. They consist of transponders inserted into objects, of readers, and usually of a database which contains information about ...
