Title:
Post-Quantum Signatures

Authors: Johannes Buchmann, Carlos Coronado, Martin Döring, Daniela Engelbert, Christoph Ludwig, Raphael Overbeck, Arthur Schmidt, Ulrich Vollmer, Ralf-Philipp Weinmann

Abstract:

Digital signatures have become a key technology for making the Internet and other IT infrastructures secure. But in 1994 Peter Shor showed that quantum computers can break all digital signature schemes that are used today and in 2001 Chuang and his coworkers implemented Shor s algorithm for the first time on a 7-qubit NMR quantum computer. This paper studies the question: What kind of digital signature algorithms are still secure in the age of quantum computers?
