Abstract
An edit data generation unit concatenates the message authentication code of an X−1th data block with the message authentication code of an Xth data block, thereby generating Xth edit data. An additional data generation unit generates the message authentication code of the Xth edit data, and extracts a portion of the message authentication code of the Xth edit data as Xth additional data. A packet generation unit generates an Xth packet including the Xth data block and the Xth additional data. A packet transmitting unit transmits the Xth packet.
