Abstract: In order to satisfy the demand of mobile secure communication for quantum keys, this study proposes a commercial quantum key distribution (QKD) based quantum key injection scheme for mobile terminals. It integrates a quantum network with a classic network, employs a quantum key injection device, and applies an encryption strategy to securely transmit the quantum key from the quantum network to the classic network for injection into a mobile terminal.Experimental results in a real quantum key distribution environment show that the fusion network runs stably, and the injection of the quantum key at the mobile terminal is realised effectively, which can meet the demands of mobile secure communication for quantum keys.

Keywords: quantum key; mobile key injecting; commercial QKD; mobile secure communication; quantum network; classic network; QKD; quantum key distribution; quantum key injection device; encryption strategy; fusion network.
