[0037] The data preprocessing module receives and preprocesses the data transmitted by the power system. The quantum key generation and distribution module generates a quantum key and transmits it to the data encryption module. The data encryption module encrypts the data and generates a ciphertext to be transmitted to the 5G wireless transmission module. The 5G wireless transmission module sends the data to the data receiving and decryption module through the power 5G wireless virtual private network. After receiving the data, the ciphertext and check code are transmitted to the verification module for verification. If the verification passes, the data encryption and decryption module uses the corresponding quantum key to decrypt the ciphertext and restore the original distribution automation data for analysis and decision-making of the power system. During the whole process, the key management and update module regularly updates the quantum key according to factors such as data transmission volume and communication duration to ensure the security of encryption.

[0042] The encryption algorithm adopted by the data encryption module is a hybrid encryption algorithm combining symmetric encryption and asymmetric encryption, which realizes double protection of power data and effectively resists various attacks.

[0043] For real-time control data, a lightweight symmetric encryption algorithm is used for fast encryption to meet low latency requirements. For non-real-time monitoring data and management data, a more secure asymmetric encryption algorithm is used.

The wireless transmission unit is used to transmit encrypted data, the real-time monitoring unit is used to monitor the transmission process in real time, and the backup transmission unit is used to make a backup connection when the transmission is interrupted to ensure the integrity of the transmission.

[0047] The real-time monitoring unit uses machine learning algorithms to monitor and predict 5G wireless channels in real time, sensing channel parameters such as signal strength, interference levels, and multipath fading. Based on the channel status, it dynamically adjusts encryption algorithm parameters and transmission rates. When channel quality is good, encryption strength and transmission rates are increased. When interference or fading are present, it switches to a more robust encryption mode and reduces the transmission rate to ensure reliable data transmission.

The risk assessment unit is used to perform risk assessment on quantum keys in real time and predict the risk level.
