==============================================================
Zusammenfassung:

The fair evaluation and comparison of side-channel attacks and countermeasures
has been a long standing open question, limiting further developments in the
field. Motivated by this challenge, this work proposes a framework for the
analysis of cryptographic implementations that includes a theoretical model and
an application methodology. The model is based on weak and commonly accepted
hypotheses about side-channels that computations give rise to. It allows
quantifying the effect of practically relevant leakage functions with a
combination of security and information theoretic metrics, respectively
measuring the quality of an implementation and the strength of an adversary.
>From a theoretical point of view, we demonstrate formal connections between
these metrics and discuss their intuitive meaning. From a practical point of
view, the model implies a unified methodology for the analysis of side-channel
key recovery. The proposed solution allows getting rid of most of the
subjective parameters that were limiting previous specialized and often ad hoc
approaches in the evaluation of physically observable devices. It typically
determines the extent to which basic (but practically essential) questions such
as ``How to compare two implementations?" or ``How to compare two side-channel
adversaries?" can be fairly answered. In order to justify the interest and
relevance of these theoretical results, we will cover a few applications of the
model, based upon both simulations and real measurements of cryptographic
hardware devices.
