Unconditionally-secure and reusable public-key authentication

Quantum Physics 2011-08-16 v1

Abstract

We present a quantum-public-key identification protocol and show that it is secure against a computationally-unbounded adversary. This demonstrates for the first time that unconditionally-secure and reusable public-key authentication is possible in principle with (pure-state) public keys.
