Promoting Scientific Activities

Scientific events organisation

The team has organised the international conference ECC 2015 — 19th Workshop on Elliptic Curve Cryptography in Bordeaux from September 28 to September 30 and a Summer School on elliptic curves the week before from September 23 to September 25.

The three day conference with 170 participants comprised about fifteen invited lectures by world-renowned scientist, presenting the major advances of the previous year. Topics ranged widely from new mathematical and algorithmic results on elliptic curves and abelian varieties, over implementations and attacks of cryptosystems up to practical studies on real-world use of curve based cryptography. This year, a panel discussion on the standardisation of elliptic curves for cryptographic use was also organised.

The preceding summer school with about 70 participants included four invited lectures of three hours each (one of which was given by Damien Robert), and a software tutorial on Sage and Pari/GP. The tutorial on Pari/GP was done by Bill Allombert and Karim Belabas. The school concluded with an afternoon of computer exercices.
