PROBLEM TO BE SOLVED: To solve such a problem of a data diode device for ensuring one-way communication of data that since delivery confirmation (ACK) cannot be received, it is required to prevent loss of a packet by ensuring the transmission quality.SOLUTION: When transmitting data from a transmitter 20 to a receiver 30 via a one-way transmission line 40, data information including serial number is added by compressing the data, data of a plurality of times including those in the past are packaged into one frame and transmitted from package data transmission means 25 thus using the band width effectively. On the receiver side, the data is extracted in the order of serial number from the data of a plurality of times thus received, and the lost data is restored from the data to be transmitted next time, thus ensuring the data transmission quality. |
