Abstract
Description
− メッセージ認証を有する非暗号化伝送(情報理論的安全性付き)
− 暗号化メッセージ伝送(情報理論的にストリーム暗号−ワンタイムパッドの安全性を有する蓋然性がある。例えば、冒頭に挙げた Gisin 他の論文参照。)
− メッセージ認証を有する暗号化伝送(共に情報理論的安全性付き)
− 非暗号化伝送
− ネットワーク節点21の中央鍵管理要素13から隣接ネットワーク節点(上記の意味)の鍵管理要素13への秘密(鍵)Cの伝送(「伝達」)。この機構によりネットワーク20の任意節点21間における秘密(鍵)Cの配送が可能となり、その結果、前述した量子暗号の距離的制約を克服する。
− ネットワーク20における障害を取り除くために鍵の経路指定を負荷分散して行うこと。
− 特定のリンクが故障した場合に代替リンクを介して鍵Cの経路指定を行うこと。
− 既に接続されている2つのネットワーク節点間のネットワーク構造に他の経路(グラフ理論的意味)を介して新たに挿入された修正量子暗号ネットワークリンク用の初期秘密の配送。
Claims (5)
- 量子通信路(4)及び公開通信路(5)を有する量子暗号リンク(1)を含むネットワーク(20)用の節点装置(21)であって、秘密又は鍵の量子暗号生成用でそれぞれの量子通信路との接続用の量子光学手段(11)、対称秘密又は鍵の管理手段(13)、暗号文生成用の暗号手段(14)及びこれに接続され公開通信路を介してその送信を行う駆動手段(15)を含み、前記対称秘密又は鍵の管理手段(13)及び前記暗号手段と前記駆動手段(14、15)が複数の量子通信路リンク用の中央要素(13、14、15)としての共同節点モジュール(24)内で結合され、他方、前記量子光学手段(11)が前記複数の量子通信路リンク用の分散モジュール(23)に分離して設けられることを特徴とする、節点装置。
- 前記共同節点モジュール(24)が、更なる中央要素として、前記管理要素(13)及び前記暗号要素(14)と接続されたネットワーク要素(27)を含むことを特徴とする、請求項1記載の節点装置。
