ATHENE-Forschende verbessern Grundlagen moderner Verschlüsselung

ATHENE-Forschende entwickeln auf die neuesten Entwicklungen angepasste Werkzeuge zur Analyse kryptografischer Schlüsselableitungsfunktionen – ETSI-Standard angepasst

(PresseBox) (Darmstadt, )
Die Verschlüsselung von Daten ist einer der zentralen Mechanismen der Cybersicherheit. Eine der wichtigsten Komponenten praktischer Verschlüsselungssysteme sind die sogenannten Schlüsselableitungsfunktionen (Key Derivation Function, KDF). Sind sie unsicher, ist die gesamte Verschlüsselung unsicher. ATHENE-Forschende der TU Darmstadt haben jetzt zusammen mit Forschenden der ETH Zürich und IBM das klassische KDF-Sicherheitsmodell aus dem Jahr 2010 grundlegend überarbeitet, sodass auch moderne Protokolle und quantensichere Kryptografie analysiert werden können. Ein erstes praktisches Ergebnis dieser Arbeit ist eine Anpassung im KDF-Standard von ETSI. Die Arbeit des Forschungsteams wurde auf der Eurocrypt 2025 (International Conference on the Theory and Applications of Cryptographic Techniques), einer der
