Titre:<\/strong> Apports de TLS 1.3 \u00e0 la s\u00e9curit\u00e9 des communications sur internet<\/p>\n R\u00e9sum\u00e9 :<\/strong><\/p>\n Le protocole SSL\/TLS, n\u00e9 en 1994 chez Mozilla, est aujourd’hui une brique essentielle pour la s\u00e9curisation des communications sur internet. SSL\/TLS a \u00e9t\u00e9 l’objet de nombreuses attaques depuis 2011, ce qui a amen\u00e9 la communaut\u00e9 scientifique et les acteurs industriels \u00e0 chercher des solutions. Ces efforts ont men\u00e9 \u00e0 une nouvelle version du standard, TLS 1.3, qui devrait prochainement voir le jour sous forme d’une RFC.<\/p>\n Dans une premi\u00e8re partie, SSL\/TLS sera bri\u00e8vement d\u00e9crit, avec un petit historique, de SSLv2 \u00e0 TLS 1.2. Une seconde partie s’attachera \u00e0 pr\u00e9senter les faiblesses du protocole et la mani\u00e8re dont TLS 1.3 r\u00e9pond au probl\u00e8me. Enfin, dans une derni\u00e8re partie, les limites de TLS 1.3 seront discut\u00e9es et des perspectives seront dress\u00e9es concernant le travail \u00e0 venir pour assurer.<\/p>\n Biographie :<\/strong><\/p>\n Olivier Levillain est chef du centre de formation \u00e0 la SSI au sein de l’agence nationale de la s\u00e9curit\u00e9 des syst\u00e8mes d’information (ANSSI). Auparavant, il a travaill\u00e9 dans les laboratoires de la sous-direction expertise de l’ANSSI, sur des sujets vari\u00e9s allant des attaques sur les m\u00e9canismes bas-niveau des architectures mat\u00e9rielles aux infrastructures de gestion de cl\u00e9s. Plus r\u00e9cemment ses travaux ont port\u00e9 sur les protocoles r\u00e9seau s\u00e9curis\u00e9s (et plus particuli\u00e8rement SSL\/TLS, le sujet de sa th\u00e8se) et les langages de programmation (\u00e9tudes JavaSec et LaFoSec, pr\u00e9sentation Mind Your Languages).<\/p>\n Ses publications sont disponibles sur https:\/\/paperstreet.picty.org\/yeye<\/p>\n","protected":false},"excerpt":{"rendered":" S\u00e9minaire R3S pr\u00e9sent\u00e9 par Olivier Levillain, le Vendredi 18 mai 2018 \u00e0 14h00 en H218 \u00e0 T\u00e9l\u00e9com SudParis (Evry).
