Zusammenfassung:	A Controller 20 sends to a Consumer 40 a command for reserving a plug/port in order to send/receive data using an Asynchronous transmission (Step 211 ) and receives information on a port connecting from the Consumer 40 (Step 212 ). The Controller 20 further sends to a Producer 30 a command for reserving a port/plug for sending content or the like (Step 213 ) and receives from the Producer 30 information on a Producer plug/port used for transmission (Step 214 ). After this, the Controller 20 notifies the Consumer 40 of the information on the port of the Producer 30 (Step 215 ) and receives a response from the Consumer 40 (Step 216 ). Next, the Consumer 40 issues a device authentication request command to the Producer 30 (Step 219 ) and they perform mutual device authentication and exchange of keys (Step 217 ).
