SHARCS'06 - Special-purpose Hardware for Attacking Cryptographic Systems
SHARCS'06 is the second workshop dedicated to the challenging subject
of special-purpose cryptanalytical machines. The first SHARCS workshop
took place 2005 in Paris and attracted 120 participants from industry,
academia and government organization. In the upcoming workshop we
intend to include more contributed talks and therefore encourage
submissions to the areas listed below.
Much of the earlier work on special-purpose hardware was done on key
searches for symmetric-key algorithms, with a particular emphasis on
attacks against DES. More recently there has been interest in hardware
architectures for sieving methods for attacking the RSA
scheme. However, it seems that much work remains to be done including,
for instance, special purpose hardware crackers for:
- index calculus algorithms
- elliptic curve based schemes
- lattice based schemes
- specific block and stream ciphers
In addition to algorithmic issues, it is also the workshop's goal to make
advances on implementational issues such as:
- optical devices for cryptanalysis
- analog computers for cryptanalysis
- FPGAs for cryptanalysis
- clusters of standard computers for cryptanalysis
- routing protocols and other low-level tools
The ultimate objective of SHARCS is to determine whether special
purpose hardware poses a real threat for today's cryptographic
algorithms, and whether there are advantages over software-based
attacks. Since this is an intrinsically interdisciplinary subject, it
is hoped that the workshop can bring together researchers with
different backgrounds for discussing and advancing this exciting
The workshop will consist of invited keynote presentations and some
contributed presentations. We welcome submissions of extended
abstracts (at least 3 pages.) We would like to stress that we do not
aim at receiving contributions on side channel attacks. Furthermore,
at this point we exclude quantum cryptologic devices. Theoretical
papers analyzing the feasibility and costs of attacks using
specialized hardware are, however, very much welcomed.
The following speakers have confirmed giving an invited talk:
- Jens Franke
(Rheinische Friedrich-Wilhelms Universität Bonn)
On the factorization of RSA200
- Kris Gaj (George Mason University)
Elliptic Curve Method of Factoring in Reconfigurable Hardware
- Alan Gara (BlueGene System Architect, IBM)
BlueGene/L: An overview and exploration into unique architectural
features that can be exploited for cryptanalysis.
- Yusuf Leblebici (École Polytechnique Fédérale
How Much Faster Can We Go? : A Technology Outlook
The workshop is organized by the European Network of Excellence
(ECRYPT). The workshop is an activity of ECRYPT's
Virtual Application and Implementation Research Lab.
SHARCS'06 takes place in
Cologne, Germany, April 03-04, 2006, in the
Dorint Kongress Hotel
Call for papers:
There will be no formal proceedings, but a handout with abstracts will be
provided to all participants. (This avoids submissions to SHARCS from
conflicting with submissions to forthcoming conferences with
Call for contributions:
|February 17, 2006: ||submission of abstracts|

Colossus in Bletchley park
At last SHARCS, Tony Sale talked about the rebuilt colossus in Bletchley
park. Currently, the
Codes and Ciphers Heritage Trust
is raising funds to build a museum in H block. So the initial conflict
that BPT wanted to sell the property seems to be resolved. To actually
build the museum, donations are still warmly welcome.
