Endogenous security network data processing method and system based on quantum key

The invention provides an endogenous security network data processing method and system based on a quantum key, and the method comprises the following steps: S1, constructing a security message: when an encrypted data packet needs to be transmitted, a source node and a target node send a sub-key request to a quantum random number generator, and the sub-key request is sent to the quantum random number generator; storing the obtained quantum key in a security area, and encrypting data by using a symmetric encryption algorithm to form a security message; s2, copying and distributing data, namely copying the security message to be transmitted into a plurality of same data packets; and step S3, constructing a plurality of heterogeneous transmission paths, constructing the plurality of heterogeneous transmission paths according to the transmission requirements of the data packets, and transmitting the plurality of copied same data packets to the target node from the plurality of heterogeneous transmission paths.
