Abstract

【課題】共有暗号ファイルの作成、リネーム、削除操作に際して、暗号鍵の更新、暗号ファイルの再暗号化等の面倒な処理を行うことなく、暗号化、復号を実現すること。 【解決手段】クライアントコンピュータ１のフィルタドライバ１２は、任意のアプリケーションからの共有暗号ファイルの読み出し要求または格納要求に対し、要求を一時捕捉し、クライアント認証を鍵管理サーバ２により受け、アクセスが許可されている共有暗号フォルダのそれぞれに対応するＵＮＣパス名と暗号鍵との対からなる鍵リストを鍵管理サーバ２から取得し、共有暗号フォルダのうち前記読み出し要求先または格納要求先の共有暗号フォルダにアクセスし、アクセスするＵＮＣパス名に関連するＵＮＣパス名が前記鍵リスト内に存在していた場合に、当該ＵＮＣパス名に対応する前記鍵リスト内の暗号鍵を用いて共有暗号ファイルの復号または暗号化を行う。
