PROBLEM TO BE SOLVED: To prevent increase of transmission delay.SOLUTION: The communication system includes: a decoding part of received encoded data; a generation part that, when receiving a piece of decoded data and an addition value, in which a header of the first protocol which includes the decoded data in a payload and the decoded data are added in a predetermined size unit, generates a packet including the decoded data, a header of a first protocol, headers of second and third protocols lower than the first protocol; a calculation part that calculates a checksum value which is set in the header of the second protocol using the addition value; and a transmission part that transmits a packet in which a checksum value is set.SELECTED DRAWING: Figure 5 【課題】伝送遅延の増加を抑える。【解決手段】通信装置は、受信された暗号化データの復号部と、復号データと、前記復号データをペイロードに含む第１プロトコルのヘッダと復号データを所定サイズ単位で加算した加算値とを受信する場合に、復号データ，第１プロトコルのヘッダ，第１プロトコルより下位の第２及び第３プロトコルのヘッダを含むパケットを生成する生成部と、加算値を用いて第２プロトコルのヘッダに設定されるチェックサム値を算出する算出部と、チェックサム値が設定されたパケットを送信する送信部とを含む。【選択図】図５
