Abstract

　暗号化通信開始のトリガ発生から実際に暗号化通信が開始されるまでの時間を短縮する。 　通信端末１１とゲートウェイ装置２５との間の通信の暗号化に用いる鍵情報を交換するための鍵交換処理を行うに際し、ネットワーク中継装置１５で中継し、鍵交換処理の内容を前半処理と後半処理との２つに区分し、前半処理をネットワーク中継装置１５において通信端末１１に代わって実行し、「ＩＫＥ ＳＡ」を確立する。そして、前半処理の結果得られた情報をネットワーク中継装置１５から通信端末１１に転送する。その後、通信端末１１とゲートウェイ装置２５との間で、鍵交換処理の後半処理を実行し、通信端末１１とゲートウェイ装置２５とで共通の鍵情報を共有して「ＩＰｓｅｃ ＳＡ」を確立し、この鍵情報を用いて暗号化通信を行う。
