2010/10/19
In this work, we study position-based cryptography in the quantum setting. The aim is to use the geographical position of a party as its only credential. On the negative side, we show that if adversar...

Recently, position-based quantum cryptography has been claimed to be unconditionally secure.
On the contrary, here we show that the existing proposals for position-based quantum cryptography are, in ...
