Description

  • Speaker

    Thomas Prest

I will present the remaining lattice-based candidates for standardization by NIST (2 signature schemes, 5 encryption schemes). At a high level, these can all be interpreted as straightforward instantiations of decades-old paradigms. But when we look under the hood, all of them make design choices which impact their security, efficiency and portability in distinct manners; we will discuss these. Finally, we will look at ninja tricks that can be pulled off with specific lattice-based schemes; in *some* contexts, these allow, with minimal changes to the schemes, to greatly decrease their communication overhead.

    Le mécanisme d'encapsulation de clé Classic McEliece faisait partie des candidats toujours en lice au dernier tour du processus de standardisation de la cryptographie post-quantique initié par le NIST en 2016. Fondé sur les codes correcteurs d'erreurs, en particulier autour du cryptosystème de Niederreiter, sa sécurité n'a pas été fondamentalement remise en cause. Néanmoins, un aspect important du[…]
