Laboratoire Spécification et Vérification

Founded in 1997, the Laboratoire Spécification et Vérification (LSV) is the Computer Science laboratory of ENS de Cachan, and is also affiliated to the French Centre National de la Recherche Scientifique (CNRS) as UMR 8643. Research at LSV is focused on the verification of critical software and systems, as well as on the verification of computer system security.

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.
