[HGI-News-de] HGI-Kolloquium am 02.05.2013: Challenges in Lattice-Based Cryptography

[Newsletter des Horst Görtz Instituts]

Sehr geehrte Damen und Herren,

im Rahmen des HGI-Kolloquiums, organisiert vom Lehrstuhl für
Systemsicherheit und dem Horst-Görtz-Institut der Ruhr-Universität
Bochum, wird Michael Schneider von der TU Darmstadt am nächsten
Donnerstag, den 02. Mai 2013 um 11.00 Uhr s.t. in Raum ID 04/413 über
folgendes Thema referieren:

Challenges in Lattice-Based Cryptography
Lattice-based cryptography is one of the most promising candidates for
future cryptography. The security of lattice-based schemes relies on the
hardness of lattice problems that remain secure even in the presence of
large-scale quantum computers. But so far, lattice-based cryptosystems
come with a few issues that have to be addressed before a real-world
rollout can take place.
In the area of cryptanalysis, there is still no common approach of
assessing the practical security of latti­ce-based schemes. In addition,
there are new heuristic improvements to the strongest algorithms for
cryptanalysis that have to be taken into account.
>From the implementation point of view, lattice-based schemes are
supposed to be easy to implement. They only apply simple operations like
matrix or polynomial multiplication and addition. A closer look re­veals
the necessity to implement these operations in a fast and clever manner,
in order to make the sche­mes comparable to classical cryptosystems.
We give an overview of the challenges in both areas, cryptanalysis as
well as practical implementations.

Zu diesem und sämtlichen weiteren Vorträgen des HGI-Kolloquiums
