To Infinity and Beyond: Combined Attack on ECC Using Points of Low Order
We present a novel combined attack against ECC implementations that exploits specially crafted, but valid input points. The core idea is that after fault injection, these points turn into points of very low or...

The World Is Not Enough: Another Look on Second-Order DPA
In a recent work, Mangard et al. showed that under certain assumptions, the (so-called) standard univariate side-channel attacks using a distance-of-means test, correlation analysis and Gaussian templates are ess...

Revisiting Higher-Order DPA Attacks:
Security devices are vulnerable to side-channel attacks that perform statistical analysis on data leaked from cryptographic computations. Higher-order (HO) attacks are a powerful approach to break protected im...

Partition vs. Comparison Side-Channel Distinguishers: An Empirical Evaluation of Statistical Tests for Univariate Side-Channel Attacks against Two Unprotected CMOS Devices
Given a cryptographic device leaking side-channel information, different distinguishers can be considered to turn this information into a successful key recovery. Such proposals include e.g. Kocher’s original DPA...

Differential Cluster Analysis
We propose a new technique called Differential Cluster Analysis for side-channel key recovery attacks. This technique uses cluster analysis to detect internal collisions and it combines features from previousl...

Fault Analysis Study of IDEA
We present a study of several fault attacks against the block cipher IDEA. Such a study is particularly interesting because of the target cipher’s specific property to employ operations on three different algebra...

Comparative Evaluation of Rank Correlation Based DPA on an AES Prototype Chip
We propose a new class of distinguishers for differential side-channel analysis based on nonparametric statistics. As an example we use Spearman’s rank correlation coefficient. We present a comparative study o...

Perfect Matching Disclosure Attacks
Traffic analysis is the best known approach to uncover relationships amongst users of anonymous communication systems, such as mix networks. Surprisingly, all previously published techniques require very speci...

Mutual Information Analysis
We propose a generic information-theoretic distinguisher for differential side-channel analysis. Our model of side-channel leakage is a refinement of the one given by Standaert et al. An embedded device containin...

Power and Fault Analysis Resistance in Hardware through Dynamic Reconfiguration
Dynamically reconfigurable systems are known to have many advantages such as area and power reduction. The drawbacks of these systems are the reconfiguration delay and the overhead needed to provide reconfigur...
