Multi-fusion gateway information encryption publishing method and device

The invention relates to the technical field of electric power automation, provides an intelligent gateway, and particularly relates to a multi-fusion gateway information encryption publishing method and device. Based on a fusion networking system, the fusion networking system comprises a first network and a second network, and the method comprises the following steps: packaging data; constructing a signaling bearing channel between the converged non-access layer and the converged gateway; transmitting the encapsulated data through the signaling bearing channel; carrying out authentication on the fused non-access layer; after the authentication is passed, establishing a service bearing channel with the fusion gateway; carrying out de-encapsulation on the received data; carrying out two-layer network forwarding on the de-encapsulated data; matching the data in the two-layer multicast group table item, and sending the matched information to a workstation; according to the technical scheme provided by the embodi
