A first communication device (100) is made up of an encryption key storage memory (130), a message storage memory (140), a system memory for the storage of programs (150), a processor (120), and a data input/output device (110). The first communication device communicates with a second communication device (200) through a transmission path (400). The second communication device is made up of an encryption key storage memory (230), a message storage memory (240), a system memory for program storage (250), a processor (220), and a data input/output device (210). The processor (220) in second communication device (200) receives a key from a key generator (300) outside of the second communication device (200). |
