Description
本発明は一般的にコンピュータ・システムの安全保護方法およびシステムに関する。本発明は更に詳細にコンピュータ・システム内の情報の安全性を確保するための方法並びに装置に関し、此処でこのコンピュータ・システムはネットワーク環境に接続されている場合もある。
インターネットの出現および広範囲におよび展開に伴い、従来型コンピュータ・システムでは不完全であることが分かってきた。インターネットの欠点はこれが従来型コンピュータ・システムの周囲防衛システムに対して多くの侵入方法を許すことである。例えば、有害なウィルス・プログラムをファイアウォールを通してコンピュータ・システムの中に注入することが可能である。これはデータおよびコンピュータ・プログラム、従ってそれから派生する機能、例えばディジタル式権利管理などを危うくする可能性がある。
(概要)
此処で使用されるように、「コンピュータ・システム」はこれに限定するわけではないが、デスクトップ・コンピュータ・システム、ラップトップ・コンピュータ・システム、ネットワーク接続コンピュータ・システム、携帯電話およびPDAの様な無線システム、内蔵型ウェブ・カメラを含むディジタル・カメラ、そして/またはこれらのシステムおよび装置の適切な組み合わせを含む。
・プログラムおよびデータ用のローカルまたは遠隔記憶装置を使用するコンピュータ・システムに対して内部安全保護を提供する。この記憶装置は単一コンピュータ・システム内に存在できる1つまたは複数の記憶装置とすることが出来る。コンピュータ・システムは1つのバスまたはネットワークに接続されることが出来る。
・コンピュータ・システムが記憶装置に依存している場合に、コンピュータ・システムをネットワークからの攻撃からの保護。
・データおよびコンピュータ・プログラムの非認証使用およびコンピュータ装置そして/またはシステム内でのコピーの保護。
・記憶装置に対して秘密鍵そしてまたメッセージの署名とチェックの安全保護および隠匿を隠されたそして認証された方法で許可する。
・ローカルな領域または広範な企業領域内の、電子的または電気光学データおよびコンピュータ・プログラムに依存する、既存のコンピュータ安全保護システムの更新。
・コンピュータ・システム内でのデータそして/またはコンピュータ・プログラムの安全で正確な機能が実現されるように、データおよびコンピュータ・プログラムを記憶装置に対して広帯域そして/または狭帯域非交換そして/または交換網を通して送信すること。
・公開鍵インフラに対する公開鍵を送信、格納および管理すること;および暗号化使用のための秘密鍵を送信、格納および管理すること。
・ローカル領域および広域の両方に渡る、マルチメディア・オーディオおよびビデオコンテンツの完全性および権利を管理すること。
・通常使用時の記憶装置の性能を妨げることの無い、記憶装置安全保護を提供すること。
・ANSI ATA-4およびATA-5ホスト保護領域の使用を改善すること。
・複数のネットワーク接続コンピュータ・システムにまたがるオペレーティング・システムの動作保証と完全性;コンピュータ・システム内でのアプリケーション・システム;複数のネットワーク接続コンピュータ・システムにまたがるアプリケーション・システム;コンピュータ・システム内の予備および復元システム;そして、複数のネットワーク化されたコンピュータ化システムにまたがる予備および復元システム、を提供すること。
・複数の記憶装置そして/またはコンピュータ・システム相互間そして/またはそれぞれ内部でのワンタイム・パッド暗号化の生成および使用を許可すること。
