Presentation of the Seminar


Cryptography is a young and active science, interesting governmental agencies and, more recently, scientists and businessmen. It allows the development of secure remote services and the protection of confidential data.

Cryptography is a multidisciplinary science, with links with number theory, algebraic geometry, algorithmic and computer science. It gives practical issues to large developments in pure mathematics, and provides new challenges.

Involved Organizations

  • DGA Information Superiority [DGA-MI]: French Defence technical center for information warfare, in charge of building cryptographic algorithms, belonging to the french Delegation for Armament [DGA].
  • Institut de Recherche Mathématiques de Rennes [IRMAR]: research institute in mathematics involving the Centre National de la Recherche Scientifique [CNRS], the University of Rennes 1, the École Normale Supérieure of Cachan [ENS Cachan], the Institut National des Sciences Appliquées of Rennes [INSA Rennes] and the University of Rennes 2.

With this seminar, these partners intend to develop the interest in cryptography of the main players of the region of Rennes, beyond the current trend, engage into a successful high level scientific collaboration.

Scientific board

The scientific board is in charge of the organization and the program of the seminar. Its members are:


Invited speakers can chose the form of their talk. They may propose a one-hour talk, or of instance two shorter talks. Since the audience of this seminar come from either cryptography, computer science or mathematics, it is however preferable to clearly introduce the domain of the talk.

Several talks on similar subjects may be grouped together, to get different approaches of a same domain in one afternoon.


Invitations of various duration (from one to four weeks) are as well organized by the board. These invitations allow researchers from IRMAR and DGA-MI to work with a guest on a specific subject in algorithmics or cryptography.
