Position-Based Quantum Cryptography: Impossibility and Constructions [PDF]
, 2010 The aim of position-based cryptography is to use the geographical position of a party as its only credential. In this work, we study position-based cryptography in the quantum setting. We show that if collaborating adversaries are allowed to pre-share an
