    • A transmission device, which continues consistent secure communication, even if a frame counter is reset due to a power cut off, includes a transmission frame counter that counts a value monotonically incremented for each packet transmission and holds the value as a frame counter value. The transmission device includes a transmission unit that adds the frame counter value held in the transmission frame counter to a packet, and transmits the packet to the reception device, and a storage circuit that stores the frame counter value. The transmission frame counter (i) stores the counted and held frame counter value into the storage circuit for each stored-frame-counter updating increment that is a natural number greater than an increment by which the frame counter value is monotonically incremented, and holds, as a new frame counter value, the stored frame counter value added with the stored-frame-counter updating increment, when the transmission device is reset.
