Abstract
According to one embodiment, a first key sharing module outputs a common key, a first cryptographic module encrypts plaintext data and outputs encrypted data. A first transmission system transmits the encrypted data. A second transmission system transmits the common key. A monitor device is disposed in the first transmission system, and receives transmission condition data from a first base and reception condition data from a second base, and performs matching of the transmission condition data and the reception condition data.
