The invention discloses a
QUIC protocol
secure transmission method based on hierarchical
encryption, and the method comprises the steps: collecting control message data, sensor data and
video image data, and adding feature parameters to the data; introducing an XGBoost
decision tree model, and training the XGBoost
decision tree model by using the data added with the characteristic parameters to obtain a trained XGBoost
decision tree model; dividing
data input into the model into control message data, sensor data and
video image data by using the trained XGBoost
decision tree model; the control message data is classified as a high-
level data layer, the sensor data and the
video image data are classified as a secondary data layer, and the data sending end encrypts the high-
level data layer and the secondary data layer respectively to obtain encrypted data streams; in combination with the
QUIC protocol, the data sending end encapsulates and integrates the encrypted data streams into the
QUIC encrypted data packets, and completes the
secure transmission of the data, thereby achieving the improvement of the
encryption efficiency and overall performance of the QUIC protocol.
