Il comitato IETF (Internet Engineering Task Force), responsabile dello sviluppo dei protocolli e dell'architettura di Internet, ha pubblicato il RFC 8996, che classifica ufficialmente i protocolli TLS 1.0 e 1.1 come tecnologie obsolete. <\/p>\n

La specifica TLS 1.0 \u00e8 stata pubblicata nel gennaio del 1999. Dopo sette anni, \u00e8 stato rilasciato l'aggiornamento TLS 1.1, che ha introdotto miglioramenti per la sicurezza, legati alla generazione di vettori di inizializzazione e a riempimenti. Secondo il servizio SSL<\/a> Pulse al 16 gennaio mostra che il protocollo TLS 1.2 \u00e8 supportato dal 95,2% dei siti web che consentono connessioni sicure, mentre TLS 1.3 \u00e8 al 14,2%. Le connessioni tramite TLS 1.1 sono consentite dal 77,4% dei siti HTTPS, e TLS 1.0 dal 68%. Circa il 21% dei primi 100.000 siti, riportati nel ranking di Alexa, non utilizza ancora HTTPS. <\/p>\n

I principali problemi del TLS 1.0\/1.1 sono la mancanza di supporto per le moderne cifrature (ad esempio, ECDHE e AEAD) e l'obbligo specificato nelle norme di supportare vecchie cifrature, la cui affidabilit\u00e0 \u00e8 stata messa in discussione con l'evoluzione della tecnologia informatica (ad esempio, \u00e8 richiesto il supporto per TLS_DHE_DSS_WITH_3DES_EDE_CBC_SHA, mentre MD5 e SHA-1 sono utilizzati per la verifica dell'integrit\u00e0 e dell'autenticazione). Il supporto per algoritmi obsoleti ha gi\u00e0 portato all'emergere di attacchi come ROBOT, DROWN, BEAST, Logjam e FREAK. Tuttavia, questi problemi non costituivano vulnerabilit\u00e0 del protocollo e sono stati affrontati a livello di implementazione. Nei protocolli TLS 1.0\/1.1 non ci sono vulnerabilit\u00e0 critiche utilizzabili per attacchi pratici.
