Former LSV student breaks the SHA1 cryptographic hash function

Visit website for this news

Elie Bursztein, a former PhD student under Jean Goubault-Larrecq, and head of the anti-abuse research team at Google, Inc., Mountain View, CA, USA, has just publicized a major breach into the SHA1 cryptographic hash function, in common work between his team and Amsterdam's CWI. That attack was produced by using a combination of recent cryptoanalysis techniques run on CPU clusters and GPU clusters at Google, and allows one to produce counterfeit documents.

This attack has devastating consequences. SHA1 is used routinely to make Web sites secure, notably merchant sites (SSL/TLS), as well as email (PGP/GPG), backup systems, and is also used in everyday tools such as Git. Its estimated cost of only 110 000 USD makes it tractable.

For details of the attack, see the group's site: shattered.io.


LSV Statement on the Secure Electronic Documents database TES

Visit website for this news

Le Laboratoire Spécification et Vérification (LSV), laboratoire d'informatique de l'ENS Paris-Saclay et du CNRS affirme que l'instauration du nouveau fichier "titres électroniques sécurisés" prévue par le décret №2016-1460, comporte un risque inhérent majeur d'attaque, vol et détournement à l'heure où les attaquants informatiques disposent de moyens considérables et croissants. Le LSV ne connaît pas de solution technique centralisée permettant de réaliser toutes les fonctionnalités prévues par le décret tout en garantissant la confidentialité des données des citoyens.
