Abstract
A certificated quantum cryptography method is provided. The method is performed by a quantum cryptography server connected to a first communication device and a second communication device which perform quantum key distribution. The method includes step of receiving a first quantum public key generated by the first communication device and a second quantum public key generated by the second communication device and registering measurement outcomes of the first and second quantum public keys. When first basis information and second basis information acquired by performing quantum key distribution between the first and second communication devices are signed and exchanged, the method includes the step of receiving a third quantum public key and a fourth quantum public key.
