International workshop on

Embedded reconfigurable architectures for applied cryptography

- CryptArchi 2003



Saint-Victor-sur-Loire castle near Saint-Etienne

January 9, 10, 11 2003



The workshop is organized in the frame of French national research program ACI Cryptologie and as a part of the project CryptArchi: Embedded Architectures for Applied Cryptography.


Aims of the workshop:

1. Exchange of information about research activities of participants

2. Discussion of the problems concerning embedding of a complete cryptographic system in reconfigurable devices
   - control and security aspects
   - architecture aspects
   - protocol aspects
   - key generation and key management aspects

3. Proposition of the structure of an ideal reconfigurable device aimed for cryptographic applications

4. Proposition of the architecture of an embedded cryptographic system based on available reconfigurable device families

5. Definition of problems concerning complete and secure embedded cryptographic system design based on reconfigurable devices

Discussion about the design of embedded architectures for applied cryptography based on recent CLD families: solutions and problems to be solved:

Since an ideal CLD specified in previous discussion does not exist we will try to specify architectures of embedded cryptographic systems based on recent CLDs with characteristics as close as possible to an ideal system. Some problems to be solved should arise from this discussion.



Saint-Victor-sur-Loire - the workshop place:

At the west of Saint-Etienne, 15 km from the center of the town, the village of Saint-Victor-sur-Loire was built on a rocky spur, which dominates the Gorges of the Loire River and the Grangent Lake. Fortified village, Saint-Victor-sur-Loire keeps from the middle age period a castle (conference site), some shaded narrow streets and a roman church.

Moreover its rich historical patrimony, Saint-Victor-sur-Loire is also the port of Saint-Etienne and one of the most important French inland marinas with 300 sites.

The castle is surrounded with a small park. Jazz concerts are organized in a small theatre situated in the park. There are two conference rooms available in the castle. A small art gallery is used to organize expositions of regional artists. The restaurant of the castle with a very nice bird's-eye view of the river valley can accommodate about 50 persons.


Access to the TSI Laboratory Saint-Etienne:

Saint-Etienne is the second biggest town of the Region Rhône-Alpes. The town is situated in the center of France, about 60 km from Lyon. The TSI Laboratory is situated in La Métare city area (in the Internet site follow >Plan d’accès).

The best way to come to Saint-Etienne from abroad is to come to Paris (Roissy Airport) and to take the fast train (TGV) to Saint-Etienne. The journey lasts 2h50.


Workshop photos:

Both small size pictures and full size pictures (behind small pictures) will be available only until the end of April!
