    Quantum Key-Recovery on AEZ

    Résumé : AEZ is an authenticated encryption algorithm, candidate in the CAESAR competition. While some classical analysis on the algorithm have been published, the cost of these attacks is beyond the security claimed by the designers.
    In this talk, I’ll present how all the versions of AEZ are completely broken against a quantum adversary, using a generalisation of Simon’s quantum algorithm for period finding.

    Lieu : Bât. Descartes, Salle 301
