Abstract

PURPOSE:To securely certify an opposite-side communication device by using 2nd secret data for certification even when 1st secret data for confirmation is leaked, by using the two secret data for certification for each communication device. CONSTITUTION:At each communication device 1, processing is carried out to set the 1st and 2nd secret data for certification peculiar to each device. Then, when confidential information is transmitted from one communication device to another device for sharing the information by using a power cipher device 5, the legality of the opposite-side device 1 is confirmed by each communication device 1 by using the 1st secret data 1 for certification. Furthermore, the legality of the opposite-side communication device 1 is certified by each device 1 by using a common cipher device 6 and the 2nd secret data for certification. Therefore, confidential information (such as a code key, password, etc.,) can be shared by plural communication devices.
