Beschreibung
Zusammenfassung:	The invention provides a cross-network data exchange device and method, and belongs to the technical field of communication, and the device comprises an extranet processing unit which is used for carrying out the security detection of an extranet data flow, and carrying out the repackaging of the extranet data flow under the condition that the security detection is passed, and obtaining a first one-way data flow; the first one-way isolation control unit is used for transmitting the first one-way data stream to the intranet processing unit according to a one-way data transmission mode; the intranet processing unit is used for performing security detection on the intranet data stream, and re-packaging the intranet data stream under the condition that the security detection is passed, so as to obtain a second one-way data stream; and the second one-way isolation control unit is used for transmitting the second one-way data stream to the external network processing unit according to a one-way data transmission mo
