ABSTRACT:
A cryptographic information repeater installed in a system for transmitting information among a plurality of subscribers interconnected by a communication line. The repeater acts as a managing center for managing cryptokeys. Therefore, confidentiality can be effectively preserved because a common secret key is not shared by all the subscribers. When some subscriber withdraws or a new user enters, it is only necessary to update the database concentrated in the cryptographic information repeater. Therefore, if the number of subscribers increases, it will not be cumbersome to manage the data.
