Abstract:
PROBLEM TO BE SOLVED: To simply establish safe communication between a device at a place where a conference is held and a device at a place where the conference is not held.SOLUTION: A communication system comprises: a relay device for controlling communication on a first network; a second terminal capable of connecting with the first network; and a third terminal capable of connecting with a second network. The relay device stores terminal identification information to identify the third terminal associated with the second terminal, transmits relay device identification information and terminal authentication information on the third terminal to the second terminal via the first network, authenticates terminal authentication information received via the second network from the third terminal, and connects the third terminal with the first network if the terminal authentication information on the third terminal is successfully authenticated. The second terminal transmits the relay device identification information and the terminal authentication information to the third terminal via the second network. The third terminal transmits the terminal authentication information to the relay device identified with the relay device identification information via the second network.SELECTED DRAWING: Figure 1
