Erg\u00e4nzt wird die Verschl\u00fcsselung noch durch den Zwang zur Authentifizierung der Kommunikationsteilnehmer. Die Bezeichnung SSL ist inzwischen abgel\u00f6st durch die Bezeichnung TLS (Transport Layer Security). Ge\u00e4ndert hat sich dabei nur die Bezeichnung. Die zu Grunde liegende Technologie ist gleich geblieben und zum Teil tragen Software-Pakete und -Bibliotheken aus historischen Gr\u00fcnden noch SSL im Namen, obwohl sie auf dem inzwischen weiter entwickelten TLS basieren.
