Our aim was to bring together researchers coming from coding theory and cryptography. More than 140 participants (77 academics, 27 studients, 19 researchers from industry 2026;) coming from 31 countries attended the workshop -- France (54), United States (13), Russia (13), Sweden (8), Germany (6), Norway (6), Spain (4), Italy (4), Irland (3), South Korea (3), United Kingdom (3), Canada, Finland, Lituania, The Netherlands, Denmark, Belgium, Bulgaria, Libanon, Israel, Malawi, India, Japan, Mexico, Australia, Singapore, Hong Kong2026; A wide range of topics were addressed during the meeting, from the more fundamental, as finite fields theory (dicrete logarithm) and designs to subjects closer to industrial applications as cryptography, convolutional coding or decoding of block codes. Algebraic coding theory was treated in all its variety, from the classical problems as code classification or parameter determination to more recent concerns as codes over rings. Cryptography was also represented in all its components. Let us mention also that some of the talks have treated of the interactions between coding and cryptography.
The program committee was composed of:
It has chosen 56 papers among 92 submissions, all of very good scientific level. All 92 submitted abstracts have been reviewed by two referees. For some papers, the members of the program committee have received help from other researchers: Mehdi-Laurent Akkar, Daniel Augot, Thierry Berger, Pascale Charpin, Pierrick Gaudry, Olav Geil, Henri Gilbert, Philippe Guillot, Johan P. Hansen, Fredrik Jönsson, Torleiv Kloeve, Pierre Loidreau, Subhamoy Maitra, Jean-François Misarsky, Cyril Prissete, Nicolas Sendrier, Christian Thommesen, Jacques Traoré and Gerardo Vega-Hernandez.
In addition we had four outstanding invited talks given by T. Ericson, J. Massey, F. Morain and T. Helleseth.
This electronic book contains all extended abstracts of accepted contributed talks and the abstract of Tor Helleseth's invited talk.
