This volume contains the proceedings of the 12th conference on Arithmetic,
Geometry, Cryptography and Coding Theory, held in Marseille, France from
March 30 to April 3, 2009, as well as the first Geocrypt conference, held in
Pointe-à-Pitre, Guadeloupe from April 27 to May 1, 2009, and the European
Science Foundation exploratory workshop on Curves, Coding Theory, and
Cryptography, held in Marseille, France from March 25 to 29, 2009.

The articles contained in this volume come from three related
symposia organized by the group Arithmétique et Théorie
de l'Information in Marseille. The topics cover arithmetic properties
of curves and higher dimensional varieties with applications to codes
and cryptography.
