Sebastiaan Indesteege sera au séminaire de l'ÉNS le vendredi 15 mai à 11 heures en Salle S16, Passage Saumon. Il expliquera le design de la fonction LANE et présentera la cryptanalyse de différents candidats à la compétition SHA-3.
Titre de la présentation : "On the design and cryptanalysis of cryptographic hash functions"
Résumé : Most of the current research on cryptographic hash functions is at least in some way related to the SHA-3 competition organised by the National Institute of Standards and Technology (NIST). This competition aims to select the next generation hash function standard, as recent cryptanalytic advances have raised serious concerns regarding the long-term security of several popular hash functions such as MD5 and SHA-1.
Teams from all over the world have submitted new hash function designs to this competition. Of the 64 hash function proposals that were submitted to NIST, 51 have been accepted to the first round of evaluations. A thorough evaluation of the security of all candidates is required in order to allow a good selection to be made.
This talk touches upon several topics related to the SHA-3 competition. The design of the hash function LANE is presented, as well as cryptanalysis of several other SHA-3 candidates.
