ファームウェア TPM (fTPM) のセットアップ

ファームウェア TPM (fTPM) では特別なプロセッサ/SoC サポートを必要とするため、現在 Raspberry Pi 2 では fTPM が実装されていません。

  1. UEFI バージョン 0.80 以上の MBM が必要です。

  2. 次の UEFI 設定を変更して、fTPM を有効にします。

     Device Manager -> System Setup -> Security Configuration -> PTT = <Enable>

  3. sTPM/dTPM の C:\Windows\System32\ACPITABL.dat がないことを確認します (競合を解決する/不要な場合はファイルを削除する)。

  4. 適切な TPM バージョンが有効になっていることを確認 - Windows IoT Core デバイスで TPM 2.0 ツールを実行します。

個別の TPM (dTPM) をセットアップする

これらの手順は、MBM、RPi2、または RPi3 でサポートされているすべての dTPM モジュールに適用されます。

  1. 個別の TPM モジュールを取得し、MBM/RPi2/RPi3 にアタッチします。

  2. (MBM に適用) 次の UEFI 設定を変更して、fTPM を無効にします。

    Device Manager -> System Setup -> Security Configuration -> PTT = <Disable>

  3. (MBM に適用) 次の UEFI 設定を変更して、fTPM を有効にします。

    Device Manager -> System Setup -> Security Configuration -> Discrete TPM = <Enable>

  4. 選択した個別の TPM モジュールに基づいて、対応する ACPI テーブルをここで特定します。

  5. その ACPI テーブルを MBM/RPi2/RPi3 C:\Windows\System32\ACPITABL.dat にコピーします。

  6. デバイスで testsigning を有効にする。

    bcdedit /set {current} integrityservices disable
bcdedit /set testsigning on

  7. デバイスを再起動します。

  8. 適切な TPM バージョンが有効になっていることを確認 - Windows IoT Core デバイスで TPM 2.0 ツールを実行します。
