Data security transmission system and method based on 5G communication in industrial network scene

The invention relates to a data security transmission system and method based on 5G communication in an industrial network scene. The system comprises a service hiding module which is used for obtaining response data of internal communication equipment responding to a request of a mobile terminal, adding a disturbance data piece to the response data through an intelligent gateway, and determiningself-disturbance data; a split data signature module which is used for splitting the self-disturbance data and signing the split self-disturbance data by utilizing a group signature technology to determine to-be-forwarded fragmented data; a data forwarding module which is used for carrying out line planning on the to-be-forwarded fragmented data, generating a forwarding pseudo-random table and randomly forwarding the to-be-forwarded fragmented data; and a data recovery module which is used for acquiring the randomly forwarded fragmented data to be forwarded, deleting the disturbance data pieces added by the service hi
