Abstract

A method for issuing a quantum key chip, a method for applying a quantum key chip, an issuing platform and a system. The method comprises: feeding, by a a quantum key issuing platform, a quantum key into a quantum key chip and binding an ID of the quantum key chip in a one-to-one correspondence to an ID of a user using the quantum key chip, where the ID of the quantum key chip and/or the ID of the user serve as identification information of the quantum key in the quantum key chip, and the quantum key is obtained by pre-negotiation between the quantum key issuing platform and a key distribution center (KDC); and sending, by the quantum key issuing platform, the identification information of the quantum key to the KDC, so that the KDC binds the identification information to the quantum key corresponding to the identification information.
