Abstract

　認証システムは、サーバ装置（１００）とアクセス用端末（１１０）との間でデータ通信を行う主通信手段（１０１）と、認証用の鍵ペアを生成する鍵生成手段（１０２）と、生成した公開鍵を蓄積するデータ記憶手段（１０３）と、生成した秘密鍵を認証用機器（１５０）に送信する補助通信手段（１０４）と、補助通信手段から送信されてくる認証用の秘密鍵を蓄積するアクセスデータ記憶手段（１０６）と、から構成される。サーバ装置は、補助通信手段を用いて実データが一定の通信量に達する毎に公開鍵１及び秘密鍵１を自動更新し、主通信手段は一定通信量に達する毎にアクセス用端末から再認証が行われない場合には通信を遮断する。アクセス用端末は、主通信手段との通信が一定通信量に達する毎に秘密鍵１が正しく更新されているかどうかを判定する。
