Abstract
Registered network-based identification corresponding to any of networks is stored in a key device. A terminal devicesends ciphertext and network-based identification to the key device, using a network. The key devicereceives the sent ciphertext and network-based identification and outputs response information corresponding to a decrypted value of the ciphertext when the network-based identification corresponds to the registered network-based identification. The terminal deviceobtains the decrypted value from the response information.
