    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...

    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...

    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...

    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...
