Quantencomputer vs. Kryptografie

Forschungsprojekt: Signatur-Verfahren der TU Darmstadt und der genua mbh soll Angriffen von Quantencomputern standhalten

(PresseBox) (Kirchheim bei München, )
Die Kryptografie gerät zunehmend unter Druck: Weltweit werden erhebliche Anstrengungen in die Entwicklung von Quantencomputern gesteckt - sobald diese extrem leistungsfähigen Rechner einsatzfähig sind, können die derzeit verwendeten Public-Key-Verschlüsselungsverfahren keinen Schutz mehr bieten. Denn die schwer lösbaren Rechenaufgaben, auf denen diese Verfahren basieren, kann ein Quantencomputer innerhalb kurzer Zeit knacken. Auch digitale Signaturen, mit denen bspw. Software-Hersteller ihren Kunden heute die Echtheit von zugesandten Updates garantieren, werden mittels Kryptografie erzeugt und verlieren somit beim großen Entwicklungssprung ihre Wirksamkeit. Erforderlich sind somit neue Sicherheitsverfahren, die Quantencomputern standhalten.
