[0074] Quantum key distribution is a key distribution that uses the characteristics of quantum mechanics to ensure the security of communications. It enables both parties in communication to generate and share a random, secure key to encrypt and decrypt messages. Under the traditional quantum key distribution scheme, optical transport network equipment (OTN equipment) obtains quantum security keys by requesting fixed cryptographic service platform nodes. Different cryptographic service platform nodes synchronize keys through QKD (quantum key distribution), so that different OTN devices can obtain the same session key.

[0075] However, the traditional quantum key distribution scheme has the following problems: OTN devices access a fixed cryptographic service platform to obtain working keys. When the access address of the quantum cryptographic service platform changes, the OTN device will not be able to perceive the change in the access address, resulting in key acquisition failure; when the quantum cryptographic service platform fails, the OTN device cannot automatically switch to the new quantum cryptographic service platform node to obtain the key, resulting in key acquisition failure.

[0076] The present invention proposes an information processing method, the purpose of which is to realize the dynamic management of the access address of the OTN device to the quantum cryptography service platform through the management platform, so as to solve the problem that when the access address of the quantum cryptography service platform changes or the quantum cryptography service platform fails, the OTN device will fail to sense the abnormality, resulting in communication failure and key acquisition failure. In order to achieve this goal, the embodiment of the present invention associates and stores the platform information of the quantum cryptography service platform and the device identification of the OTN device through the management platform, and the platform information includes the platform identification and access address of the quantum cryptography service platform, so that the management platform can query the platform information of the quantum cryptography service platform corresponding to the OTN device according to the device identification of the OTN device, thereby ensuring the communication between the OTN device and the quantum cryptography service platform and avoiding the failure of key acquisition.

[0077] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0078] Reference Figure 1, shows a flowchart of the steps of an information processing method according to an embodiment of the present invention, which is applied to a management platform. The method may specifically include the following steps:

[0079] Step 101, obtaining platform information of a quantum cryptography service platform and a device identifier of an OTN device corresponding to the quantum cryptography service platform; the platform information includes a platform identifier and an access address of the quantum cryptography service platform;

[0080] In an embodiment of the present invention, the management platform can obtain the platform information sent by the quantum cryptography service platform and the device identification of the OTN device corresponding to the quantum cryptography service platform. Among them, the platform information of the quantum cryptography service platform may include the platform identification of the quantum cryptography service platform (i.e., the quantum cryptography service platform ID) and the access address; the device identification of the OTN device may include the device serial number and the SPMID (Service Provider Message ID, service provider unique identifier) ​​assigned by the quantum cryptography service platform to the OTN device. Through the platform identification of the quantum cryptography service platform and the SPMID of the OTN device, an association relationship between the quantum cryptography service platform and the OTN device can be established to improve the efficiency of the OTN device accessing the quantum cryptography service platform.

[0081] Among them, the quantum cryptography service platform includes: platform management service, cryptographic operation service, key management service, API gateway service and other modules, which have flow limiting alarm function, complete cryptographic operation function and key management function, and support data persistence and background service management. Platform management service is used to provide tenant management, application management, key management, authentication management, authorization management, device management, cross-domain management, platform monitoring, system management and other capabilities. Cryptographic operation service is used to provide symmetric operation, asymmetric operation, hash operation and other capabilities. Key management service is used to provide management capabilities for working keys, asymmetric keys, injection keys, session keys and cross-domain key synchronization capabilities. API gateway service is used to provide flow limiting alarm, authentication, load balancing, and logging capabilities.

[0082] OTN equipment is mainly deployed between the integrated service access point of the metropolitan area network or local network and the customer equipment. It is connected to the OTN equipment placed in the integrated service access node at the central office through the line-side OTN interface to achieve the convergence of access services. Through the highly secure quantum cryptography service platform, OTN equipment can achieve end-to-end service encryption transmission, achieving the advantages of zero bandwidth loss, low encryption delay, and no perception of upper-layer services.

[0083] Step 102, storing the platform information of the quantum cryptography service platform and the device identification of the OTN device in association with each other;

[0084] In an embodiment of the present invention, the management platform can associate and store the platform information of the quantum cryptography service platform with the device identification of the OTN device, so as to quickly query the access address of the quantum cryptography service platform corresponding to the OTN device through the SPMID of the OTN device.

[0085] Step 103: After receiving the first information acquisition request sent by the OTN device, query the platform information of the quantum cryptography service platform corresponding to the OTN device according to the device identification of the OTN device carried in the first information acquisition request, and send the platform information to the OTN device, so that the OTN device communicates with the quantum cryptography service platform according to the access address.

[0086] In an embodiment of the present invention, after the management platform receives the first information acquisition request sent by the OTN device, it can query the platform information of the quantum cryptography service platform corresponding to the OTN device according to the device identification of the OTN device carried in the first information acquisition request, and send the platform information to the OTN device, so that the OTN device can communicate with the quantum cryptography service platform according to the access address.

[0087] Specifically, the management platform can determine the corresponding quantum cryptography service platform ID through the SPMID or device serial number of the OTN device, and query the access address of the quantum cryptography service platform according to the quantum cryptography service platform ID, and then send the access address to the OTN device, so that the OTN device can communicate with the quantum cryptography service platform according to the access address.

[0088] In one embodiment, the method may further include the following steps: after the access address of the quantum cryptography service platform is updated, obtaining address update information of the quantum cryptography service platform; the address update information includes the platform identifier of the quantum cryptography service platform and the updated access address; according to the updated access address, updating the access address corresponding to the platform identifier.

[0089] In an embodiment of the present invention, the management platform can re-acquire the address update information sent by the quantum cryptography service platform after the access address of the quantum cryptography service platform is updated; the address update information includes the platform identifier of the quantum cryptography service platform and the updated access address. The management platform can update the access address corresponding to the platform identifier according to the updated access address, so that when the access address of the quantum cryptography service platform changes, the OTN device can obtain the updated access address through the management platform to communicate with the quantum cryptography service platform, thereby avoiding the OTN device from failing to communicate due to the inability to perceive the update status of the access address of the quantum cryptography service platform.

[0090] In one embodiment, the method may further include the following steps: after receiving a second information acquisition request sent by the OTN device, determining a new quantum cryptography service platform corresponding to the OTN device according to the device identification and communication failure information of the OTN device carried in the second information acquisition request; obtaining new platform information of the new quantum cryptography service platform; the new platform information includes a new platform identification and a new access address of the new quantum cryptography service platform; and sending the new platform information to the OTN device.

[0091] In an embodiment of the present invention, when the quantum cryptography service platform fails, the OTN device cannot communicate with the quantum cryptography service platform according to the access address provided by the management platform. At this time, the OTN device can send a second information acquisition request to the management platform, and the second information acquisition request includes the device identification of the OTN device and the communication failure information. Among them, the communication failure information is used to characterize that the quantum cryptography service platform corresponding to the device identification of the OTN device has failed. After receiving the second information acquisition request sent by the OTN device, the management platform can allocate a new quantum cryptography service platform to the OTN device according to the device identification and communication failure information of the OTN device carried in the second information acquisition request; obtain the new platform information of the new quantum cryptography service platform; the new platform information includes the new platform identification and new access address of the new quantum cryptography service platform; and then send the new platform information to the OTN device. In this way, the automatic switching of the fault when the OTN device accesses the quantum cryptography service platform is realized through the management platform, avoiding the communication failure of the OTN device due to the inability to access the quantum cryptography service platform.

[0092] In the embodiment of the present invention, the platform information of the quantum cryptography service platform and the device identification of the OTN device corresponding to the quantum cryptography service platform can be obtained through the management platform, and the platform information of the quantum cryptography service platform and the device identification of the OTN device are associated and stored, so that the association relationship between the OTN device and the quantum cryptography service platform can be managed through the management platform, and the dynamic management of the access address of the quantum cryptography service platform can be realized at the same time; after receiving the first information acquisition request sent by the OTN device, the platform information of the quantum cryptography service platform corresponding to the OTN device is queried according to the device identification of the OTN device carried in the first information acquisition request, and the platform information is sent to the OTN device, so that the OTN device communicates with the quantum cryptography service platform according to the access address, so that the management platform can ensure the communication between the OTN device and the quantum cryptography service platform by managing the access address of the quantum cryptography service platform and the association relationship between the OTN device and the quantum cryptography service platform.

[0093] Reference Figure 2, shows a flowchart of another information processing method according to an embodiment of the present invention, which is applied to a quantum cryptography service platform. The method may specifically include the following steps:

After the quantum master key charging is completed, the quantum cryptography service platform can obtain its own platform information and the device identification of the OTN device corresponding to the quantum cryptography service platform; the device identification may include the device serial number and SPMID of the OTN device, and the platform information may include the platform identification and access address of the quantum cryptography service platform. Among them, the device identification is used to determine the platform identification of the quantum cryptography service platform corresponding to the OTN device, the platform identification is used to determine the access address of the quantum cryptography service platform, and the access address is used for the OTN device to communicate with the quantum cryptography service platform.

[0096] Among them, the key charging software is the "endurance station" of quantum key resources. It supports the use of Ukey (USB Key, a small storage device connected to the computer through a USB interface) for charging administrator authentication; supports adaptation to different forms of security media such as secure U-shield, secure SIM card, TF card and software password module; supports the selection of charging of different sizes of keys; supports batch charging of multiple security media.

[0097] Step 202: Send the platform information of the quantum cryptography service platform and the device identification of the OTN device to a management platform, so that the management platform associates and stores the platform information and the device identification.

[0098] In an embodiment of the present invention, the quantum cryptography service platform can send platform information and device identification to the management platform, so that the management platform associates and stores the platform information and device identification, and after receiving the first information acquisition request sent by the OTN device, quickly query the access address of the corresponding quantum cryptography service platform through the device identification of the OTN device, and return the access address to the OTN device. The embodiment of the present invention improves the efficiency of the OTN device accessing the quantum cryptography service platform and ensures the communication between the OTN device and the quantum cryptography service platform.

The management platform can update the access address corresponding to the platform identifier according to the updated access address, so that when the access address of the quantum cryptography service platform changes, the OTN device can obtain the updated access address through the management platform to communicate with the quantum cryptography service platform, thereby avoiding the OTN device from failing to communicate due to the inability to perceive the update status of the access address of the quantum cryptography service platform.

[0103] Reference Figure 3 , shows a flowchart of another information processing method according to an embodiment of the present invention, which is applied to OTN equipment. The method may specifically include the following steps:

[0104] Step 301, sending a first information acquisition request to a management platform; the first information acquisition request includes a device identifier of the OTN device;

[0105] In an embodiment of the present invention, the OTN device sends a first information acquisition request to the management platform, where the first information acquisition request includes a device identifier of the OTN device and is used to obtain platform information of a quantum cryptography service platform corresponding to the OTN device.

[0106] Step 302: receiving the platform information of the quantum cryptography service platform corresponding to the OTN device, which is queried by the management platform according to the first information acquisition request; the platform information includes the platform identifier and access address of the quantum cryptography service platform;

[0107] In an embodiment of the present invention, the OTN device can receive the platform information of the quantum cryptography service platform corresponding to the OTN device, which is queried by the management platform according to the first information acquisition request; the platform information includes the platform identifier and access address of the quantum cryptography service platform, which is used for the OTN device to communicate with the quantum cryptography service platform.

[0108] Step 303: communicate with the quantum cryptography service platform according to the access address.

[0109] In an embodiment of the present invention, the OTN device can communicate with the quantum cryptography service platform according to the access address. Exemplarily, the OTN device can send a key acquisition request to the quantum cryptography service platform according to the access address of the quantum cryptography service platform. The quantum cryptography service platform can generate a session password or query a session password based on the device serial number, SPMID, session key identifier and other information carried in the key acquisition request, and return the session password to the OTN device.

[0110] In one embodiment, the method may further include the following steps: after communication with the quantum cryptography service platform fails, sending a second information acquisition request to the management platform; the second information acquisition request includes the device identification of the OTN device and communication failure information; receiving new platform information of a new quantum cryptography service platform determined by the management platform according to the communication failure information; the new platform information includes a new platform identification and a new access address of the new quantum cryptography service platform; and communicating with the new quantum cryptography service platform according to the new access address.

[0111] In an embodiment of the present invention, after failing to communicate with the quantum cryptography service platform, the OTN device may send a second information acquisition request to the management platform, and the second information acquisition request includes the device identification of the OTN device and the communication failure information. The OTN device may receive the new platform information of the new quantum cryptography service platform determined by the management platform according to the communication failure information, and communicate with the new quantum cryptography service platform according to the new access address; wherein the new platform information includes the new platform identification and new access address of the new quantum cryptography service platform.

[0112] When the OTN device fails to communicate with the quantum cryptography service platform again, it can continue to send a second information acquisition request to the management platform so that the management platform can re-determine a new quantum cryptography service platform corresponding to the OTN device. The number of second information acquisition requests that the OTN device can send can be a preset failure number threshold, and the preset failure number threshold can be determined based on the number of standby quantum cryptography service platforms corresponding to the quantum cryptography service platform stored by the management platform. The embodiment of the present invention does not limit the number of standby quantum cryptography service platforms.
