PROBLEM TO BE SOLVED: To provide a security communication system capable of automatically setting communication setting information necessary for communication between security devices facing with each other even under a network environment having different address spaces between which a router or the like lies.SOLUTION: A router 12 records, in a routing table 123, connection information on a security device 11A, 11B in which there has been a registration request. On the other hand, when the security device 11A, 11B gets connected to a network 10A, 10B, the security device 11A, 11B requests registration of connection information on the security device 11A, 11B of the router 12, searches for an opposite connection destination security device 11B, 11A of the security device 11A, 11B from the connection information recorded in the router 12A with the use of an opposite device search unit 112A, 112B, communicates with the found security device 11B, 11A with the use of a communication setting information exchanging unit 113A, 113B, and thereby generates and sets communication setting information necessary for encryption communication. |
