Workshop on Elliptic Curve Computation (ECC 2010)

In 18-22 October 2010 I visited Microsoft Research in Redmond, Washington to participate in Workshop on Elliptic Curve and Computation.

As the official press release states: "The study of Elliptic Curves has been closely connected with Machine computation almost since the invention of computers -- in 1952 Emil Artin had John von Neumann perform an extensive calculation relating to elliptic curves on the IAS MANIAC computer. The fundamental papers of Birch and Swinnerton-Dyer in 1965, which gave rise to the Birch-Swinnerton-Dyer conjecture were buttressed with extensive machine computation. There has been extensive interplay between theory and computation relating to ranks of elliptic curves, Heegner points, Galois representations, Sato-Tate distributions, and many other areas. The year 2010 marks the beginning of a 25 year period in which a number of influential papers initiated a fundamental connection between elliptic curves, cryptology and the theory of computation."

I received a full scholarship (fees, tickets, stay, etc.) to participate to the Workshop.

 

North German Algebraic Geometry Seminar, Summer Term 2010

The North German Algebraic Geometry Seminar is a joint seminar of the Algebraic Geometry groups in Bremen, FU Berlin, HU Berlin, Hamburg, Hannover, Göttingen, Groningen and Oldenburg.

I attended North German Algebraic Geometry Seminar, Summer Term 2010 at Leibniz Universität Hannover, 17.06.-18.06.2010.

GTEM 2010: Workshop on Computational Number Theory and Arithmetic Geometry

FP6 Research and Training Network GTEM [Galois Theory and Explicit Methods] organised a Workshop on Computational Number Theory and Arithmetic Geometry in Leuven-Heverlee, Belgium.

I am a Junior member of this research group and I participated in the workshop.

On of the speakers was ofcourse Prof. Dr. Gerhard Frey.

The workshop took place at May 17-21, 2010. 

There were some guided tours organised too. One was through Leuven city. I stayed with two collegues at Hotel de Pastorij.

During my stay to Belgium I had the chance to visit Liege and Brussels too. In Brussels I stayed at Hotel Beau Site.

13th Workshop on Elliptic Curve Cryptography (ECC 2009)

ECC 2009 is the 13th in a series of annual workshops dedicated to the study of elliptic curve cryptography and related areas. Over the past years the ECC conference series has broadened its scope beyond elliptic curve cryptography and now covers a wide range of areas within modern cryptography. For instance, past ECC conferences included presentations on hyperelliptic curve cryptography, pairing-based cryptography, side-channel attacks, voting protocols, quantum key distribution, AES, hash functions, and implementation issues.

This year the Workshop was hosted by The University of Calgary, August 24-26, 2009 at Calgary, Alberta, Canada.

I stayed at Travelodge (located in Motel Village, near the University of Calgary) 2227 Banff Trail NW.

I also participated to the Elliptic Curve Cryptography Summer School that was held the week before the ECC 2009 Workshop. The summer school ran from August 19 until August 22.

The scholarship committee offereed me  my accommodations for the duration of both events and the registration fees. The travel expences were coverd by the University of Oldenburg.

I have been to almost all EC Workshops since 2004 till this one.

North German Algebraic Geometry Seminar, Winter Term 2009/2010

The North German Algebraic Geometry Seminar is a joint seminar of the Algebraic Geometry groups in Bremen, FU Berlin, HU Berlin, Hamburg, Hannover, Göttingen, Groningen and Oldenburg

I attended North German Algebraic Geometry Seminar (NoGAGS), Winter Term 2009/2010  at Freie Universität Berlin, 19.11.-20.11.2009

During the event I stayed at Harnack-Haus and shared a room with my colleague Arne Grenzebach.

The organisers covered our expenses (travel, stay and registration fees).

Talk to Groningen on isogenous hyperelliptic curves of genus 2

Talk to Groningen, 13-11-2009 11:45-12:45

Marios Magioladitis,

The discrete logarithm problem on isogenous

hyperelliptic curves of genus 2

Abstract. In 2005, Jao, Miller, and Venkatesan proved that the DLP of elliptic curves with the same endomorhism ring is random reducible under the GRH. In this talk, we discuss a possible generalization of this result to hyperelliptic curves of genus 2 (and 3) defined over a finite field and show the difficulties involved. First, we explain the role of the endomorphism rings of the Jacobian and the polarization. Following the work of Jao, Miller and Venkatesan, we construct isogeny graphs for genus 2 curves. Specifically, we discuss the connection between isogenies and ideal classes in the Jacobian of these curves. This project is research in progress and we describe the current status of this research.

Workshop on Factoring Large Integers

On 11-12 September 2009. I attended a workshop on Factoring Large Numbers at the Ruhr-University Bochum (BSI-Projekt "Faktorisieren großer Zahlen").

It was organized by the Federal Office for Information Security (BSI) and the Chair of Cryptology and IT-Security.

The workshop took place in Veranstaltungsraum 2 (room number 01/53), which is located at level 01 in the mensa building.

I travelled with my collegues to Bochum from Oldenburg via Osnabrück and the return tour was via Bremen.

Invited speakers to the workshop were  Daniel J. Bernstein (University of Illinois at Chicago), Willi Geiselmann (Karlsruhe University), Antoine Joux (Université de Versailles), Tanja Lange (Technische Universiteit Eindhoven), Claus-Peter Schnorr (Goethe-University Frankfurt) and Francesco Sica.

During the evening of 11 September I went to  Starlight Express Theater for a beautiful show.
