Attacks on fixed-apparatus quantum-key-distribution schemes

Year: 2014

Type: article

Abstract: We consider quantum-key-distribution implementations in which the receiver's apparatus is fixed and does not depend on his choice of basis at each qubit transmission. We show that, although theoretical quantum key distribution is proven secure, such implementations are totally insecure against a strong eavesdropper that has one-time (single) access to the receiver's equipment. The attack we present here, the ``fixed-apparatus attack,'' causes a potential risk to the usefulness of several recent implementations.
