Title: Quantum Proofs of Knowledge - Possibility and Impossibility
Abstract:
Quantum computers, when the come, will threaten most of today's crypto. We need to think ahead and study which protocols can withstand an attacker with quantum computers. In this talk, we focus on "proofs of knowledge" and show that things get interesting there. While some protocols indeed work in the quantum setting, we show that we cannot expect such result in general.
