Encrypting data based on its metadata and the telemetric data of the upstream and downstream servers. Establish a secure connection between an upstream server and a downstream server and encrypt the data being transmitted by retrieving first telemetric data of the upstream server and second telemetric data of the downstream server at a specific time. Subsequently, aggregate the first and second telemetric data and retrieve metadata for the data being transmitted. Generate an encryption key based on the aggregated telemetric data and the metadata and use the encryption key to encrypt the data. Subsequently, the encrypted data is received and decrypted by the downstream server.

Disclosed are a data processing method, an electronic device, and a computer-readable storage medium. During uplink transmission, upon receiving a first QUIC message from a client device over a target UDP port, an NGINX server sends the first QUIC message to the QUIC protocol stack, such that the QUIC protocol stack processes the first QUIC message to derive application layer data, and sends a first data stream including a first application layer data packet to an upstream server. During downlink transmission, the NGINX server receives a second data stream from the upstream server, caches a second application layer data packet included in the second data stream into a second cache, and delivers the second application layer data packet to the QUIC protocol stack for processing when the QUIC protocol stack is writable to derive a second QUIC message and sends the second QUIC message to the client device.
