Description
貴重なコンテンツを保護するシステムには、効果的なセキュリティ対策が必要である。映画館に運ばれるフィルムなど、物理的形態で配布されるコンテンツについては、物理的セキュリティ対策で十分な場合がある。しかし残念なことに、従来の物理的セキュリティ手法は遅く、費用がかかり、煩わしく、また非物理的コンテンツ配布モデル(non−physical content distribution models)といっしょには使用できない。そのため、コンテンツプロバイダ(content providers)は許可されたユーザのみがデータにアクセスできるようにするため暗号ハードウェアに頼っている。
背景技術の多くのシステムでは、デジタルコンテンツを暗号化形式で配布している。コンテンツを復号するのに必要な鍵またはアルゴリズムへのアクセスは、コンテンツ所有者(content owner)に対しアクセスポリシー(access policies)を強制する権利管理システムによって規制される。アクセスポリシーは、それぞれ複雑さが大きく異なる。たとえば、最も単純な方式では単に支払い後に復号化鍵を渡すだけであるが、Ginter 他の米国特許第5,915,019号に記載されている方式ではかなり高度で柔軟性の高い配布メカニズムを提示している。
コンテンツ配布システムで使用する秘密鍵およびアルゴリズムを管理し保護する暗号ユニットの設計およびアーキテクチャはさまざまなものが提案され、使用されている。鍵の保護について正規ユーザが信頼に足る場合、ソフトウェア専用方式は許容できるものであり、専用ハードウェアを構築し配布するコストおよび出費を避けられる利点がある。しかし、多くの場合、不正操作防止モジュールが必要である。
非対称関数(Asymmetric Function):秘密鍵がないと補数演算(逆演算など)を簡単に計算できないが、秘密鍵があると簡単に計算できる計算しやすい関数。RSA暗号システムは、非対称と考えられるが、それは公開鍵演算を反転する(つまり、秘密鍵演算を実行する)のは秘密鍵が知られている場合のみ簡単であるためである。
図2は、本発明の暗号権利ユニット(CRU)を使用するシステム例である。コンテンツプロバイダ200は、コンテンツを取得して、たとえば、コンテンツデータを圧縮して暗号化し、複数コンテンツストリームを多重化し、KDMやREMなどの制御メッセージを追加することにより配布の準備をする。(コンテンツ準備プロセスの詳細は、以下の「コンテンツの準備」というセクションで説明する。)
CryptoFirewallは、保護メモリへのアクセスを暗号法を使用して規制する。従来のメモリ暗号化デバイス(Holteyの米国特許第5442704号の暗号化されたメモリデバイスなど)と異なり、CryptoFirewallは透過的に動作しないか、あるいはマイクロプロセッサによって任意の読み書き演算を実行できない。特に、CryptoFirewallでは、保護メモリ内にデータ値を格納し、同じ値を後で読み出す機能をマイクロプロセッサに付加する必要はない。従来のセキュアメモリ方式は通常、信頼できる計算デバイスであまり安全でないメモリにアクセスできるようにするために使用される。対照的に、CryptoFirewallは、インタフェース制御プロセッサは信頼できないが攻撃者はCryptoFirewallの背後にあるメモリへの直接的な読み書きアクセスを行わないという反対の仮定をして設計されている。つまり、CryptoFirewallでは、攻撃者がファイアウォールを完全に破り保護メモリに無制限アクセスを行えるということがない場合に、CRUの主マイクロプロセッサが損なわれたとしても暗号権利ユニットを安全なままにできる。
パーソナライゼーション中に、CHIP_KEYおよびBATCH_KEYを含むキーが追加される。製造プロセスが許可した場合、製造中に、たとえばオンチップフューズにブローすることによって、これらのキーをCryptoFirewallに格納することができる。これらを保護メモリに格納することもできるが、攻撃者があるCRUからのキー値を別のCRUへ格納できるようにすることを防止するために、配慮しなければならない。このような攻撃を防止するために使用可能な方法は、キー領域への書込みアクセスをパーソナライゼーション後に防止すること(たとえば、ライトプロテクトフューズをブローすることによる)、これらの領域へのアクセスを暗号化により規制すること、およびビットクリアまたはビット設定オペレーションを使用不可能にして、攻撃者があるキーを別のキーに変換することを防止することを含む。(有効なキーを、等しい数の設定およびクリアビットにより選択して、キーの変更にはビットの設定およびクリアが必要となるようにすることができる。)侵略的でない攻撃を使用して実行された変更が、有用な結果を生成することなくキーを破損する確率が高いとすれば、キーの修正を許可することも可能である。
擬似非対称関数は好ましいアーキテクチャに含まれ、これは、単一のデバイスが損なわれた場合、結果を制限する助けとなることができるからである。暗号プロトコルのみ(ハードウェア不正防止性なし)では、ブロードキャストコンテンツ配布システムに対する多数の攻撃を防止することができない。これは、許可された再生システムの無許可のレプリカが信号を復号化できるからである。結果として、ハードウェア実施は、リバースエンジニアリングまたはクローニングが困難であるべきである。
NANDゲート820の出力には、W0ないしW63というラベルが付けられる。これらはそれぞれX0ないしX127(835というラベルが付けられる)のうち1つまたは複数に接続され、そこで特定の接続の選択がPAFGによって行われる。XORゲート840への残りの入力が、C0...C15、K0...K127および/またはU1...U127からランダムに選択されたビットに接続される。XORゲート出力850(Y0ないしY63というラベルが付けられる)が、PAFGによって、Z0ないしZ127(855とラベルが付けられる)からランダムに選択された入力に接続される。最後のセットのNANDゲート860への残りの入力が、C0...C15、K0...K127、U1...U127、W0...W63およびY0...Y63の間から選択される。最後に、NANDゲート860の出力および元の128ビットのシフトレジスタの左側のビット805が共に、XORゲート870によってXORされ、単一ビットの結果880が生成される。次いで、128ビットのシフトレジスタ800が左に1つの位置だけシフトされ(すなわち、ビット1のコンテンツをビット0に、ビット2をビット1に、ビット127をビット126に、などのように格納する)、単一の結果ビット880がビット位置127に入れられる。入力ブロックを変換するため、図8に示すオペレーションが、各オペレーション後に、クロックカウンタ804への対応する増分または更新により繰り返し実行される。キー802も更新することができ、これはたとえば、これを最大長のシフトレジスタにより変換することによって行う。実行される反復の回数は実施に固有であり、パフォーマンス要件および混合関数の品質などの要素に応じて可変となる可能性がある。
図2ないし図7に関して記載したCryptoFirewallの複雑性を、著しく減らすことができる。このセクションでは、一般的なメモリ保護およびセキュリティ機能を維持する、1つのこのような簡素化されたアーキテクチャを概説する。最初に提示する実施形態では、CryptoFirewallがプリペイド権利のみをサポートし、他のセキュリティ機能(ポストペイメント購入監査など)を(それほど安全でない)ICPによって実施させるようにしておく。欠点は、ICPを損なう攻撃者が潜在的にポストペイメント監査レコードを消去する可能性があることであるが、利点は、CryptoFirewall実施が著しく簡素化されることである。
このセクションでは、プリペイドコンテンツ購入のためのセキュリティのみを提供する、簡素化されたCryptoFirewallアーキテクチャを概説する。この実施形態は、CryptoFirewallの後ろの書込み可能な不揮発性メモリの代りに、揮発性メモリを使用することができる利点を有する。揮発性メモリはしばしば実施しやすいので(たとえば、標準の論理コンポーネントのみが必要とされるので)、製造および設計コストを削減することができる。
CRUの物理的実装は、いくつかの形をとる可能性がある。好ましい実装形態は、インタフェース制御プロセッサ(ならびにそのメモリ)および保護メモリを単一のチップ上でCryptoFirewallおよび保護メモリと結合し、次いでこのチップをスマートカードまたはPCMCIAカード(PCカード)中に配置することを含む。CryptoFirewallセキュリティモデルは、インタフェース制御プロセッサ(ICP)が完全に安全であるとは仮定しないので、CryptoFirewallは、ICPとは別個のハードウェア、例えば同じ集積回路上の別個の回路に実装すべきである。
ディジタルコンテンツは普通、圧縮された形で配信される。種々のタイプのコンテンツを生み出し、フォーマットし、圧縮するプロセスは、背景技術で周知である。暗号化された材料はあまりよく圧縮されないので、ほとんどの状況では、コンテンツは圧縮後に暗号化される。しかし時として、圧縮と暗号化が結合されるか、または圧縮前に単純な暗号化が適用される。
図2に概要を示したアーキテクチャの元では、ICPおよびそのRAM、ROM、およびEEPROMが危険にさらされたとしても、システムはロバスト性を保つ。これは、本発明の非常に重要な特徴である。というのは、チップのこれらのコンポーネントは、侵入性の攻撃と非侵入性の攻撃の両方を特に受けやすいからである。CryptoFirewallは、保護メモリへの権利鍵の追加を制御し、それにより、あるCRUから得られた情報が、暗号を破らずにまたは侵入性の攻撃を行わずに他のCRUに権利鍵を追加する能力を攻撃者に提供することが防止される。権利鍵が危険にさらされたとしても、攻撃者は、CryptoFirewallの向こうにそれを挿入することはできない。
この章では、本発明の修正実施形態の例をいくつか提示するが、当業者には他の変形も明白であろう。
