Dans versions nocturnes<\/a><\/noindex> Firefox par d\u00e9faut le support est d\u00e9sactiv\u00e9<\/a><\/noindex> la prise en charge des protocoles TLS 1.0 et TLS 1.1 (le param\u00e8tre security.tls.version.min est d\u00e9fini sur 3, \u00e9tablissant TLS 1.2 comme version minimale). Dans les versions stables, TLS 1.0\/1.1 devrait \u00eatre d\u00e9sactiv\u00e9 en mars 2020. Dans Chrome, la prise en charge de TLS 1.0\/1.1 cessera dans Chrome 81, pr\u00e9vu pour janvier 2020. <\/p>\n

La sp\u00e9cification TLS 1.0 a \u00e9t\u00e9 publi\u00e9e en janvier 1999. Sept ans plus tard, une mise \u00e0 jour, TLS 1.1, a \u00e9t\u00e9 publi\u00e9e avec des am\u00e9liorations de s\u00e9curit\u00e9 li\u00e9es \u00e0 la g\u00e9n\u00e9ration de vecteurs d'initialisation et de remplissages suppl\u00e9mentaires. Actuellement, le comit\u00e9 IETF (Internet Engineering Task Force), qui travaille sur le d\u00e9veloppement des protocoles et de l'architecture Internet,
\nd\u00e9veloppe<\/a><\/noindex> un projet de sp\u00e9cification, d\u00e9classant les protocoles TLS 1.0\/1.1 comme obsol\u00e8tes. Selon le service SSL Pulse<\/a><\/noindex> \u00c0 la date du 3 septembre, le protocole TLS 1.2 est pris en charge par 95,8 % des sites web autorisant des connexions s\u00e9curis\u00e9es, tandis que TLS 1.3 ne l'est que par 17,7 %. Les connexions utilisant TLS 1.1 sont accept\u00e9es par 75,5 % des sites HTTPS, et celles avec TLS 1.0 par 65,5 %.<\/p>\n

Les principaux probl\u00e8mes de TLS 1.0\/1.1 sont l'absence de prise en charge des algorithmes de chiffrement modernes (par exemple ECDHE et AEAD) et l'exigence de prise en charge d'anciens algorithmes dont la fiabilit\u00e9 est remise en question \u00e0 l'heure actuelle (par exemple, le support de TLS_DHE_DSS_WITH_3DES_EDE_CBC_SHA, o\u00f9 MD5 et SHA-1 sont utilis\u00e9s pour l'int\u00e9grit\u00e9 et l'authentification). La prise en charge d'anciens algorithmes a d\u00e9j\u00e0 conduit \u00e0 des attaques telles que
\nROBOT<\/a><\/noindex>, DROWN<\/a><\/noindex>, BEAST<\/a><\/noindex>, Logjam<\/a><\/noindex> et FREAK<\/a><\/noindex>. N\u00e9anmoins, ces probl\u00e8mes n'\u00e9taient pas directement des vuln\u00e9rabilit\u00e9s du protocole et \u00e9taient r\u00e9solus au niveau de leurs impl\u00e9mentations. Il n'y a pas de vuln\u00e9rabilit\u00e9s critiques dans les protocoles TLS 1.0\/1.1 qui pourraient \u00eatre utilis\u00e9es pour mener des attaques pratiques.<\/p>\n
