F. Morain and A. Guillevic (with their co-authors R. Barbulescu and P. Gaudry) broke the discrete logarithm world record for finite fields of the form with a prime of 80 decimal digits. The new techniques form the preprint  .
D. Augot and M. Finiasz received the best paper award at FSE 2014  . FSE is the most important conference devoted to symmetric cryptography. Grace contribution is to propose a mathematical construction which enables direct construction of so-called diffusion layers in block ciphers.
