Thomas STIELTJES

ORGANIZERS

Ronald Cramer (BRICS, Aarhus), Bas Edixhoven (UL) and Berry Schoenmakers (TUE).

DATES

Start: Monday September 22, 2003, 9.30-10.00: arrival of participants at the Lorentz Center (Oortgebouw, third floor).
End: Friday September 26, 2003, 16.30, closing reception with drinks.

SPEAKERS

Courses and problem sessions on Monday through Thursday, and some of the lectures on Friday, will be given by:

The Friday concluding the Stieltjesweek is the first day of the

workshop Mathematics of Cryptology,

for which this graduate course is a preparation and introduction.

SCHEDULE

On Monday through Thursday we have the following day schedule:

On Friday the schedule is different: Graduate Course until 12:30, followed by the workshop, see the program of the workshop.

TOPICS

Discrete logarithms on elliptic curves (van Tilborg).
Point counting on hyperelliptic curves, after Kedlaya (Carls and Edixhoven).
Hash proof systems, chosen ciphertext security and public key encryption (Cramer and Fehr).
Verifiable secret sharing and secure multi-party computation (Cramer and Fehr).
Sigma protocols and applications of secure multi-party computation, e.g. electronic voting (Cramer/Fehr/Schoenmakers).

PROGRAM

See the program on the webpages of the Lorentz Center.

TEXTS

The following texts are now available on the web.

Robert Carls and Bas Edixhoven, course in postscript or in pdf and exercises (a magma implementation is available at David Lubicz's home page).
Ronald Cramer and Ivan Damgård, lecture notes (including exercises).
Berry Schoenmakers, transparencies (including exercises).
Henk van Tilborg, course and exercises.

PREREQUISITES

Participants are expected to have some experience in mathematics related to cryptography (mainly algebra and number theory), or in cryptography, and/or some experience in theoretical computer science, especially complexity theory and algorithms, for example by having studied mathematics or cryptography or theoretical computer science for at least two or better three years.

REGISTRATION

To register and to reserve hotel accomodation if necessary, send an email to Bas Edixhoven (edix@math.leidenuniv.nl), mentioning your affiliation (university/employer) and situation (student + year + field, PhD-student + field, postdoc, professor,.....).

Participation is free of charge. Standard hotel accomodation costs 70 euro (singly occupancy with breakfast), 55 (without breakfast) or 27.5 euro (double occupancy without breakfast) per person per night.

PARTICIPANTS

There is a list of registered participants.
