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.
In celebration of two decades of activity, LSV is hosting a workshop to look back at achievements in our field and to discuss challenges ahead. The programme include invited talks by partners and members of the laboratory.
Members, former members, and other interested colleagues are cordially invited to join us in Cachan on 11 and 12 May. Attendance is free, but registration is required.
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.
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.

Georg Zetzsche received the Distinguished Dissertation Award 2016 of the EATCS for his thesis Monoids as storage mechanisms at the University of Kaiserslautern, Germany. Georg Zetzsche is currently a post-doc at LSV in the INFINI axis.
Stéphanie Delaune received an ERC Starting Grant for her project POPSTAR - Physical properties Of security Protocols with an Application To contactless Systems. The objective of the project is to develop foundations and practical tools to analyse the security and privacy of modern security protocols that establish and rely on physical properties.
Stéphanie is a CNRS-Researcher, she has been a member of LSV since 2007 before joining the EMSEC team at IRISA, Rennes in September 2016.
