Abstract

PURPOSE: To make an unauthorized person difficult to read classified communication and further to carry out accurate communication between terminals by dividing the whole body of a cipher system into a cipher system of communication apparatuses in a network such as bridge, router, or the like and into a cipher system between terminals and by using the inter-terminal cipher system and the intra-network cipher system separately.
CONSTITUTION: A sending terminal 111 uses an inter-terminal cipher system 1 for dealing with information necessary to communicate with a party terminal 121 and an intra-network cipher system 2 for dealing with information necessary to carry out data transfer processing or the like in networks 11 and 12 or bridges 31 and 32. A party terminal 121 belonging to a network 12 uses the intra-network cipher system 2 to interprete part of the network of the message received from bridge 32, recognizes that the message is sent to the party terminal 121 itself, and uses the inter-terminal cipher system 1 to interprete inter-terminal information. With this, message communication between terminals 111 and 121 via networks 11 and 12 including bridges 31 and 32 or router is enciphered, thereby making an unauthorized person through networks 11 and 12 difficult to read the message communication and making it possible to carry out normal communication between terminals 111 and 121.
