The idea is encrypt partition with root filesystem using LUKS and store the keys in the TPM.
During boot user does not have to enter a decryption password, partition will be automatically decrypted using the keys from TPM.
It's a open-source alternative to Windows BitLocker.

  • LUKS (Linux Unified Key Setup) - is a full volume encryption feature, the standard for Linux hard disk encryption
  • TPM (Trusted Platform Module) - is dedicated micro-controller designed to secure hardware through integrated cryptographic keys
