Abstract
A communication system is provided with an information processing device, and a management device capable of updating old data stored in the information processing device by outputting new data to the information processing device. The management device is provided with an old data input device that inputs the old data, a first new data input device that inputs the new data, an encryption device that encrypts the new data by utilizing the old data as a key, and a new data output device that outputs the new data encrypted by the encryption device to the information processing device. The information processing device is provided with an old data storage that stores the old data, a second new data input device that inputs the encrypted new data output by the management device, a decryption device that decrypts the encrypted new data by utilizing the old data as a key, and an updating device that updates the old data stored in the old data storage to the new data decrypted by the decryption device.
