Introduction

Protecting patient Health Information (PHI) is a legal and ethical mandate. Clinical PCs deployed at nurse stations, examination rooms, or self-service kiosks must be secured against physical and network-based tampering. A hardware-based Trusted Platform Module (TPM 2.0) forms the root of trust for modern clinical operating systems.

In this guide, we configure TPM 2.0 and Secure Boot on the Horizon TM-6140-22 Medical Touchscreen Computer.

The Hardware Foundation: Horizon TM-6140-22 Medical Touchscreen Computer

The Horizon TM-6140-22 Medical Touchscreen Computer is a medical-grade touchscreen computer with built-in security features:

  • Integrated TPM 2.0: Cryptographic co-processor that securely stores keys, certificates, and passwords.
  • Secure Boot Firmware: Validates bootloaders, kernels, and driver signatures.
  • IP65 Rated Front Panel: Dust-tight and washdown-safe.
  • Intel Active Management Technology (AMT): Allows secure remote management.

Step-by-Step Security Configuration

Step 1: Enable TPM 2.0 in UEFI Firmware

  1. Boot the Horizon TM-6140-22 Medical Touchscreen Computer and enter the UEFI BIOS setup utility.
  2. Navigate to Security -> Trusted Computing.
  3. Set TPM Support to Enabled and TPM Device to PTT or dTPM.

Step 2: Enforce Full Disk Encryption (BitLocker / LUKS)

By linking disk decryption keys to the TPM PCR (Platform Configuration Register) states, the drive will only decrypt if the boot sequence is unmodified.

# On Linux, verify TPM 2.0 state and bind LUKS decryption
tpm2_pcrread sha256:0,7

Step 3: Secure Boot Verification

Verify that the operating system only executes kernels signed by trusted authorities.

Conclusion

Enabling TPM 2.0 and Secure Boot on the Horizon TM-6140-22 Medical Touchscreen Computer guarantees hardware-level protection for sensitive patient data and prevents unauthorized software modifications.
