Abstract
An authentication apparatus and method for quantum cryptography communication. The quantum cryptography communication authentication method is performed using quantum cryptography communication authentication apparatuses, and includes transmitting, by a first quantum cryptography communication authentication apparatus, a quantum state to a second quantum cryptography communication authentication apparatus by selecting a first basis, and measuring, by the second quantum cryptography communication authentication apparatus, the quantum state by selecting a second basis, and performing, by the first quantum cryptography communication authentication apparatus and the second quantum cryptography communication authentication apparatus, authentication by revealing the first basis and the second basis and by comparing sifted keys generated from a common basis between the first basis and the second basis with each other.
