Buidling blocks

Participant : Marine Minier.

In the context of the BLOC project funded by the ANR, we continue to work on Extended Generalized Feistel Network and on new ligthweight block cipher design (see [30] ). We hope to obtain results in this area at the beginning of 2015. With Christine Solnon and Julia Reboul, we work on the formalism of related-key and chosen-key attacks against symmetric key primitives using constraint programming (CP). This preliminary work was presented at the CP 2014 workshop ModRef 2014 in [42] .
