Post-Quantum Digital Signatures

Digital signatures are a key mechanism to implement authentication, e.g. of communication partners.
Unfortunately, today's wide-spread mechanisms like RSA and (EC)DSA are vulnerable to quantum computers.
Consequently, it is important to develop new digital signature schemes (as a precaution).

In this seminar, your task is to summarize and discuss post-quantum-secure signature schemes.
The discussion should focus on achievable security, computational costs, and the size of signatures and public keys.
