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.
