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. ...

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...

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...
