Sehr geehrte Damen und Herren,

im Rahmen des HGI-Kolloquiums, organisiert vom Lehrstuhl für Netz-
und Datensicherheit (NDS), wird Ilya Kizhvatov, University of
Luxembourg, am kommenden Mittwoch den 8. Dezember 2010 über
"Outperforming DPA with Collision and Cache-Collision Side Channel
Attacks" referieren.

Der Vortrag beginnt um 11:15 Uhr im ID 03/401.

Abstract:
To date, Differential Power Analysis (DPA) is known as the most
practical side-channel attack. There are however side channel attacks
that use more information about the algorithm and therefore can be more
efficient than DPA. In this talk, we focus on two examples of such
"analytic" attacks: collision and cache-collision attacks. First, we
suggest how to combine collision attacks with DPA (and any other
divide-an-conquer SCA) and how to improve collision detection. Second,
we present trace-driven cache-collision attacks that are tolerant to
errors in distinguishing cache hits from cache misses. Our experiments
with real devices show that the presented attacks work in a practical
setting and require less side-channel measurements than DPA.
The talk is based on the recent joint work with Jean-François Gallais
and Michael Tunstall (eprint:2010/408), and with Andrey Bogdanov
(eprint:2010/590).

Beste Grüße


Dominik Birk
