Qvr Trfpuvpugr qre Xelcgbtensvr - Die Geschichte der Kryptografie

(PresseBox) (Aachen, )
Am 25. Mai jährt sich bereits zum dritten Mal die europäische Datenschutzgrundverordnung. Um Daten und Informationen zu schützen und gegen Missbrauch abzusichern, gibt es viele verschiedene Ansätze. Einer der ältesten und effektivsten ist Kryptografie, also Verschlüsselung von Information. Aus dem aktuellen Anlass wirft Utimaco einen Blick auf die spannenden Entwicklungen auf diesem Feld.

1. Aller Anfang ist analog

Kryptografie wird oft mit Digitaltechnologie und Computer-Algorithmen in Verbindung gebracht. Tatsächlich ist sie aber viel älter und Algorithmen sind nicht auf die digitale Welt beschränkt. Die Überschrift dieses Textes „Qvr Trfpuvpugr qre Xelcgbtensvr“ wurde beispielsweise mit einem sehr simplen Algorithmus zqgrzezpjuehr, tyn rycvqr: „jeqivyl fsxnk Zhwwaphdby xauyv Uytnqq zc 60 Oqqqxsc ov Dzgfbouq“.
