TPM-backed full disk encryption: enhanced security with hardware integration
Ubuntu now offers experimental support for TPM-backed full disk encryption, combining the robustness of LUKS with the security benefits of a Trusted Platform Module (TPM). This approach enhances protection against offline attacks and provides a more seamless user experience.
What is a TPM?
A TPM is a specialized chip on your motherboard that securely stores encryption keys and other sensitive data. It can also perform cryptographic operations and verify system integrity.
Why use TPM-backed full disk encryption?
Traditional LUKS encryption relies on a passphrase to unlock the disk. While strong passphrases offer good security, they can be vulnerable to brute-force attacks or keyloggers if an attacker gains physical access to your computer.
TPM-backed LUKS addresses this vulnerability by storing the encryption key within the TPM itself. The key is released only after the TPM verifies the...
