제안된 플랫폼에서 TPM 설정

설치 펌웨어 TPM(fTPM)

fTPM(펌웨어 TPM)에는 특별한 프로세서/SoC 지원이 필요하며, 현재 Raspberry Pi2에서 fTPM이 구현되지 않은 경우.

  1. UEFI 버전이 0.80 이상인 MBM이 있어야 합니다.

  2. 다음 UEFI 설정을 변경하여 fTPM을 사용하도록 설정합니다.

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

  3. sTPM/dTPM용 C:\Windows\System32\ACPITABL.dat가 없는지 확인합니다(필요 없는 경우 충돌 해결/파일 삭제).

  4. 올바른 TPM 버전을 사용하도록 설정했는지 확인합니다. Windows IoT Core 디바이스에서 TPM 2.0 도구를 실행합니다.

개별 TPM 설정(dTPM)

이러한 지침은 MBM, RPi2 또는 RPi3에서 지원되는 모든 dTPM 모듈에 적용됩니다.

  1. 개별 TPM 모듈을 가져와서 MBM/RPi2/RPi3에 연결합니다.

  2. (MBM에 적용) 다음 UEFI 설정을 변경하여 fTPM을 사용하지 않도록 설정합니다.

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

  3. (MBM에 적용) 다음 UEFI 설정을 변경하여 dTPM을 사용하도록 설정합니다.

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

  4. 선택한 개별 TPM 모듈에 따라 여기에서 일치하는 ACPI 테이블을 식별 합니다.

  5. 해당 ACPI 테이블을 MBM/RPi2/RPi3 C:\Windows\System32\ACPITABL.dat에 복사합니다.

  6. 디바이스에서 테스트 서명 사용:

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

  7. 디바이스를 다시 부팅합니다.

  8. 올바른 TPM 버전을 사용하도록 설정했는지 확인합니다. Windows IoT Core 디바이스에서 TPM 2.0 도구를 실행합니다.
