[0002] Currently, quantum secure communication based on quantum key distribution (QKD) is mainly used for point-to-point key sharing and encryption of information transmission over wired networks such as VPNs (Virtual Private Networks) and routers. Exploring the combination of quantum key distribution with wireless communication encryption applications is of great value for expanding the application scenarios of quantum secure communication, opening up the commercial application market, and promoting industrial development.

[0003] Once generated, quantum keys no longer possess the security guaranteed by quantum physics properties, therefore they cannot be transmitted a second time over a communication network. By using a quantum key distribution network as the key distribution infrastructure, key filling devices can be used to fill keys onto removable storage media, such as SD cards, that meet certain security level requirements within the security management domains of different quantum key distribution network nodes.

[0004] By integrating the key storage medium with a wireless terminal that has authentication and encrypted communication functions, it is possible to use quantum keys to encrypt and protect the authentication and session key negotiation process between the wireless terminal and the encryption server, thereby providing a certain degree of quantum encryption services for encryption applications in the field of wireless communication.

[0024] Figure 4 The diagram shown is a second structural diagram of a quantum key injection test module according to an exemplary embodiment of the present invention. Detailed Implementation

[0025] The concept of this invention is that by performing communication tests, quantum key injection function tests, performance stress tests, and abnormal operation tests in sequence through a quantum key injection machine, various abnormal operations and stress tests are covered while ensuring the stable operation of the quantum key injection hardware, thus ensuring the stress resistance and stability of quantum key injection.

[0026] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0027] like Figure 1 The flowchart of the quantum key injection method and the quantum key injection test method are shown, including: Step S1: Perform a communication test between the quantum key filling machine and the quantum key management network device; Step S2: Under normal communication test conditions, perform quantum key injection function test of quantum key injection machine; Step S3: Under normal quantum key injection function, perform at least one performance stress test on the quantum key injection machine; Step S4: Under normal performance stress test conditions, perform at least one abnormal operation test on the quantum key injection machine.

[0028] like Figure 2 The diagram shows a network topology for a quantum key injection machine. The quantum key distribution network includes a quantum cryptography service management center and at least one quantum cryptography service center A, B, and C under the control of the quantum cryptography service management center. Each quantum cryptography service center includes a quantum key management device, a quantum random number generator, a quantum key injection machine, and a cryptographic machine.

[0029] A quantum random number generator is used to generate quantum random numbers. The quantum key management device integrates quantum key generation control, key storage, distribution, relay, and quantum key relay routing control. It forms a secure channel with the quantum key injector and distributes quantum keys according to the request of the quantum key injector. A cryptographic machine is a device that provides IPSec VPN functionality and information encryption. It uses quantum keys to replace traditional key exchange, providing security guarantees such as confidentiality, integrity protection, and data source authentication for data transmission within a user's internal network.

[0030] A quantum key injector is used to inject the acquired quantum key into a secure medium for convenient mobile use by subsequent users.

[0031] During the quantum key injection test, the secure channel communication between the quantum key injector and network devices, including at least the quantum cryptography service management center, is first tested to ensure its normal operation. For example, the communication between the quantum key injector and the quantum key management device is tested. After confirming normal network communication, the quantum key injector performs a normal quantum key injection function test. After confirming normal quantum key injection function, the maximum concurrent quantum key injection count is tested. Quantum key injection tests are then performed for different quantum key storage media, such as USB secure media cards, SIM cards, and SD cards. After confirming normal quantum key storage media testing, the injection rate for each storage medium is tested. Finally, anomaly tests are performed to address potential abnormal operations, including repeated quantum key injection, repeated interruption of quantum key injection, repeated abnormal restarts, and repeated insertion and removal of the injection medium.

[0032] like Figure 3 As shown, the quantum key injection machine includes a quantum key injection test module, which includes: a communication test unit 301, a functional test unit 302, a stress test unit 303, and an anomaly test unit 304.

[0033] The communication test unit is configured to perform communication tests between the quantum key injector and the quantum key management network device; the functional test unit is configured to test the quantum key injector to perform normal quantum key injecting functions under normal communication test conditions; the stress test unit is configured to perform at least one performance stress test on the quantum key injector under normal quantum key injecting function conditions; and the anomaly test unit is configured to perform at least one abnormal operation test on the quantum key injector under normal performance stress test conditions.

[0034] The filling process of the quantum key filling machine is operated by the operator user. Before performing the communication test between the quantum key filling machine and the quantum key management network device, the process also includes: adding the operator user, authenticating the operator user, and performing the communication test after the authentication is successful.

[0035] like Figure 4 As shown, the quantum key injection test module also includes an authentication unit 300, which is configured to bind users based on user information and the Ukey.

[0036] After successfully binding a user, the communication test unit 301 receives the user settings and adds network devices and interfaces, including a secure channel interface, a key distribution management interface, a secure media library, and a key management server.

[0037] When performing a functional test, the functional test unit 302 configures the number of charging bytes, and after inserting the charging medium, determines whether the charging medium has been used. If not, i.e., it has not been used, then it performs quantum key charging. If yes, i.e., it has been used, then it replaces the charging medium and performs quantum key charging.

[0038] Furthermore, an exemplary embodiment of the present invention may also provide a computer-readable storage medium storing a computer program. This computer-readable storage medium stores a computer program that, when executed by a processor, causes the processor to perform a quantum key injection testing method according to an exemplary embodiment of the present invention. This computer-readable recording medium is any data storage device capable of storing data read by a computer system. Examples of computer-readable recording media include: read-only memory, random access memory, read-only optical disc, magnetic tape, floppy disk, optical data storage device, and carrier waves (such as data transmission via the Internet through wired or wireless transmission paths).

[0039] Furthermore, an exemplary embodiment of the present invention may also provide a computing device. The computing device includes a processor and a memory. The memory stores a computer program. The computer program is executed by the processor, causing the processor to perform a computer program for a quantum key injection testing method according to an exemplary embodiment of the present invention.
