Huvudproblemen med TLS 1.0\/1.1 \u00e4r avsaknaden av st\u00f6d f\u00f6r moderna algoritmer (t.ex. ECDHE och AEAD) och kravet p\u00e5 st\u00f6d f\u00f6r \u00e4ldre algoritmer vars tillf\u00f6rlitlighet har ifr\u00e5gasatts i den moderna teknologiska utvecklingen (t.ex. kr\u00e4vs st\u00f6d f\u00f6r TLS_DHE_DSS_WITH_3DES_EDE_CBC_SHA, f\u00f6r integritet och autentisering anv\u00e4nds MD5 och SHA-1). St\u00f6det f\u00f6r f\u00f6r\u00e5ldrade algoritmer har redan lett till attacker som
\nROBOT<\/a><\/noindex>, DROWN<\/a><\/noindex>, BEAST<\/a><\/noindex>, Logjam<\/a><\/noindex> och FREAK<\/a><\/noindex>. Emellertid utgjorde dessa problem inte direkt s\u00e5rbarheter i protokollet och hanterades p\u00e5 niv\u00e5n av dess implementationer. Sj\u00e4lva protokollen TLS 1.0\/1.1 saknar kritiska s\u00e5rbarheter som kan anv\u00e4ndas f\u00f6r praktiska attacker.<\/p>\n
