[0076] like Figure 1 As shown, the first embodiment of the data security transmission method for power edge side equipment of the present invention is:

[0077] A data security transmission method for power edge side equipment includes the following contents:

[0078] Through the pre-built link authentication model, a connection is established between the edge / end device and the quantum security service platform, and a session key is generated;

[0079] Using the pre-built edge-side quantum generation model, the injection key is used to decrypt the session key to obtain the quantum key;

[0080] Based on the pre-built edge-side quantum encryption model, the quantum key is used to encrypt the storage data and / or device parameters to obtain encrypted protection data, and the quantum key is used to encrypt the business data to obtain the ciphertext encrypted by the quantum key;

[0081] A pre-built edge-side quantum decryption model is used to decrypt encrypted messages received from the power cloud-edge system network using quantum keys to obtain plaintext data, thereby achieving secure transmission of power edge / end-side device data.

[0082] In this embodiment, the method of using the pre-built edge-side quantum generation model to decrypt the session key using the injection key to obtain the quantum key is as follows:

[0083] Connect to the quantum security service platform through a dedicated key injection module to inject keys. The dedicated key injection module is marked according to the unique serial number of the quantum security module and injects keys on the quantum security service platform. The key capacity injected at a time is between 10KB and 60MB.

[0084] The key charging is completed and the charging key is obtained;

[0085] After successfully decrypting the session key through the injection key, the quantum key is obtained.

[0086] In this embodiment: Based on the pre-built edge-side quantum encryption model, the device parameters are encrypted using the quantum key to obtain encrypted protection data, and the service data is encrypted using the quantum key to obtain the ciphertext encrypted by the quantum key as follows:

[0087] Obtain device parameters and business data; device parameters are sensitive parameters of the power cloud-edge system;

[0091] The ciphertext is then imported into the controller unit MCU and transmitted in the power cloud-edge system network, ensuring that the data transmission is ciphertext encrypted by quantum keys. Even if it is intercepted, it cannot be cracked and used, thus ensuring data security.

[0092] In this embodiment: when sensitive parameters are used, the sensitive parameters are decrypted using a quantum key and then imported into the controller unit MCU.

[0093] In this embodiment: a pre-built edge-side quantum decryption model is used to decrypt the encrypted message received from the power cloud edge system network using a quantum key to obtain the plaintext data as follows:

[0094] Obtaining encrypted messages in the power cloud-edge system network;

[0095] Import the encrypted message into the quantum security module in the edge / end device;

[0096] Use quantum keys to decrypt encrypted messages.

[0097] The decrypted plaintext data is then transmitted to the controller unit MCU for data use.

[0098] An embodiment of the data security transmission system of the present invention for power edge side equipment:

[0099] A data security transmission system for power edge-end devices, applying the above-mentioned data security transmission method for power edge-end devices, comprising a power system master station, edge devices and end devices;

[0100] The power system master station is provided with a power service channel and a quantum service channel for edge devices to perform data transmission;

[0101] The edge device is provided with an edge controller unit MCU and a quantum security module 1;

[0102] The terminal device is provided with an terminal controller unit MCU and a quantum security module 2.

[0103] In this embodiment: the quantum security module 1 communicates with the edge controller unit MCU via the SPI interface and the UART interface;

[0104] The edge controller unit MCU is equipped with a communication interface 4G and a communication interface SOCKET;

[0105] The quantum security module 2 communicates with the end controller unit MCU through the interface SPI and the interface UART;

[0106] The end controller unit MCU is provided with a communication interface 4G and a communication interface SOCKET.

[0107] In this embodiment: Quantum security module 1 and quantum security module 2 are respectively configured with USB interfaces for quantum key injection and firmware upgrade.

[0108] The present invention is applicable to the data protection and encryption / decryption of edge / end devices in the electric power cloud-edge-end system to improve the security of the load control and management services of edge / end devices. The quantum security module provides sensitive data protection, data encryption and decryption services for the load control and management services of the electric power cloud-edge-end system, meeting the needs of the electric power cloud-edge-end system for secure data transmission and storage. It realizes the superposition of quantum encryption technology without changing the existing customer-side business system architecture, improving the security of power grid data communication, and thus ensuring the normal operation of the power grid.

[0109] A second embodiment of the data security transmission method for power edge side equipment of the present invention:

[0110] A data security transmission method for power edge-end devices is applied to edge / end devices in the power cloud-edge-end system. It can perform quantum security protection on sensitive data stored in itself. When data is interacted with the main station, the interaction data is encrypted with quantum keys, so that all the transmissions of the socket or 4G line are ciphertext. The ciphertext received by the edge / end device is decrypted using the quantum key, thereby improving the data interaction security of the power cloud-edge-end system. The edge / end device of the present invention is used in the power cloud-edge-end system architecture such as Figure 2 shown.

[0111] In this embodiment, the physical interface design of the edge / end side device is as follows: Figure 3 As shown, the edge / end device has a built-in quantum security module and has passed the national secret level 2 qualification certification. The quantum security module communicates with the controller unit MCU through SPI and UART. The communication interface of the controller unit MCU remains unchanged, maintaining the existing 4G and SOCKET. In addition, the quantum security module is equipped with a USB interface for quantum key injection and firmware upgrade.

[0112] For edge / end devices, external data interaction is divided into quantum channel and power business channel. The quantum channel is mainly used for partial interaction with the quantum security service platform, such as device network authentication, application for session keys, etc. The internal data flow interaction between the quantum security module and the controller unit MCU is divided into network authentication, application for session keys, sensitive parameter protection, and data encryption and decryption; for the quantum security module itself, it is necessary to inject keys through dedicated injection software. The overall data flow interaction is as follows: Figure 4 shown.

[0113] For key charging services, the dedicated key charging software is used to connect to the quantum security service platform for key charging. The charging software is marked according to the unique serial number of the quantum security module. The key charging is performed on the quantum security service platform. The capacity of a single key charging is between 10KB and 60MB. For the quantum key charging process, please refer to Figure 5 .

[0114] Before using business data, edge / end devices must first join the quantum network. The edge / end devices authenticate the quantum network through the quantum channel. After successful authentication, the edge / end devices apply for a session key. After the application for the session key is successful, the session key is decrypted using the injection key to obtain the quantum key. The process is as follows: Figure 6 shown.

[0115] After successfully decrypting the session key through the injection key, the quantum key is obtained, and the quantum key is used to encrypt and store sensitive parameters of the power cloud edge system; when sensitive parameters need to be used, the sensitive parameters are decrypted using the quantum key, and then exported to the controller unit MCU; for data encryption, the quantum key is used for encryption processing, and then the ciphertext result is imported into the controller unit MCU and transmitted in the power cloud edge system network, ensuring that the data transmission is ciphertext encrypted by the quantum key, which cannot be cracked even if intercepted, ensuring data security; for the ciphertext received by the edge / end device, the quantum key is used to decrypt it, and then the decrypted plaintext data is transmitted to the controller unit MCU for data use, such as Figure 7 shown.

[0116] The present invention uses a quantum security module to protect and encrypt the data of the power cloud-edge system, securely protect sensitive data, ensure that key power parameters and switch data are encrypted for transmission, and improve the security of interactive data in the power system.

[0117] After the edge / end device establishes a link with the quantum security service platform, it performs network authentication and applies for a session key. At this time, the edge / end device has joined the quantum security network and successfully obtained the session key. After obtaining the session key, the edge / end device uses the injection key to decrypt the session key to obtain the quantum key. Then, quantum is used to protect and store sensitive data, and the business data is encrypted using the quantum key to obtain the ciphertext encrypted by the quantum key. This is transmitted in the power cloud edge system to ensure data security. After receiving the encrypted message, the edge / end device uses the quantum key to decrypt it to obtain the plaintext.
