Design and Implementation of a Waveform-Matching Based Triggering System
Implementation attacks such as side channel attacks and fault attacks require triggering mechanisms to activate the acquisition device or fault injection equipment. Most academic works work with a very simple ...

Consolidating Masking Schemes
In this paper we investigate relations between several masking schemes. We show that the Ishai–Sahai–Wagner private circuits construction is closely related to Threshold Implementations and the Trichina gate. ...

DPA, Bitslicing and Masking at 1 GHz
We present DPA attacks on an ARM Cortex-A8 processor running at 1 GHz. This high-end processor is typically found in portable devices such as phones and tablets. In our case, the processor sits in a single boa...

Inner Product Masking Revisited
Masking is a popular countermeasure against side channel attacks. Many practical works use Boolean masking because of its simplicity, ease of implementation and comparably low performance overhead. Some recent...

A Note on the Use of Margins to Compare Distinguishers
Relative distinguishing margins are becoming a popular measure for comparing distinguishers. This paper presents some examples that show that this measure, although informative and intuitively sound, should no...

Generic DPA Attacks: Curse or Blessing?
Generic DPA attacks, such as MIA, have been recently proposed as a method to mount DPA attacks without the need for possibly restrictive assumptions on the leakage behaviour. Previous work identified some shor...

Power Analysis of Atmel CryptoMemory – Recovering Keys from Secure EEPROMs
Atmel CryptoMemory devices offer non-volatile memory with access control and authenticated encryption. They are used in commercial and military applications e.g. to prevent counterfeiting, to store secrets suc...

Selecting Time Samples for Multivariate DPA Attacks
Masking on the algorithm level, i.e. concealing all sensitive intermediate values with random data, is a popular countermeasure against DPA attacks. A properly implemented masking scheme forces an attacker to ...

Theory and Practice of a Leakage Resilient Masking Scheme
A recent trend in cryptography is to formally prove the leakage resilience of cryptographic implementations – that is, one formally shows that a scheme remains provably secure even in the presence of side channel...

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...

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...
