Approaches to Post-Quantum Signatures"
Dr Christian Rechberger
(Graz University of Technology)
In this talk we survey practical ways to achieve public-key signature schemes
that are solely based on Symmetric-Key Primitives or Hash functions. This
promises to be a very conservative approach to achieve long-term security,
including resistance against future attacks which use scalable quantum
computers. In particular, we will also discuss two recent submissions to the
ongoing NIST PQ process: SPHINCS+ and PICNIC.
