Как я могу зашифровать свои данные в OrangePI? Таким образом, в случае кражи злоумышленники не смогут получить доступ к моим файлам. Какие инструменты лучше всего подходят для этой цели? Можно ли запустить устройство без парольной фразы, чтобы оно не запрашивало парольную фразу при каждой загрузке? Secure Boot и TPM? Или что то еще?
Это вообще возможно - что бы не вставлять флешку с ключем каждый раз при загрузке.
Задача для IoT, чтоб не похитили интелектуальную собственность :)
Чат ЖПТ дает что то такое предложение на запрос - How can I use luks to encrypt the whole disk in linux with secureboot using TPM (Trusted Platform Module) without password, encrypting the bootloader
Encrypting the entire disk in Linux with LUKS, Secure Boot, and TPM without a password, including encrypting the bootloader, is a bit complex. The following steps provide a general guide, but keep in mind that the details may vary depending on your specific Linux distribution and hardware. Ensure you have backups before proceeding.
Prerequisites:
-
TPM (Trusted Platform Module): Ensure your computer has a TPM.
-
Secure Boot: Ensure Secure Boot is enabled in your system’s UEFI/BIOS settings.
-
Boot from Live USB: Prepare a live USB with a Linux distribution that supports LUKS, Secure Boot, and TPM.
Steps:
-
Boot from Live USB: Boot your computer from the live USB.
-
Partition and Encrypt the Disk: Use
gdisk
or another partitioning tool to create partitions on your disk. Encrypt the root partition with LUKS:cryptsetup luksFormat --type luks2 /dev/sdXn cryptsetup open --type luks /dev/sdXn my_encrypted_volume
-
Install the System: Install the Linux distribution to the encrypted partition. During installation, ensure that the bootloader (GRUB or another) is installed to the encrypted partition, not the MBR or EFI system partition.
-
Create a Key File: Create a key file for the LUKS volume:
dd if=/dev/urandom of=/etc/luks_keyfile bs=512 count=4 chmod 0400 /etc/luks_keyfile
Add the key file to the LUKS key slots:
cryptsetup luksAddKey /dev/sdXn /etc/luks_keyfile
-
Create a TPM2 Policy: Create a TPM2 policy file:
tpm2_createpolicy -P -L policy.digest
-
Seal the Key File to TPM: Seal the LUKS key file to the TPM:
tpm2_createpolicy -L policy.digest -f policy.file tpm2_createek -c ek.ctx tpm2_createak -C ek.ctx -g sha256 -u ak.pub -f ak.priv -D policy.digest tpm2_load -C ek.ctx -u ak.pub -r ak.priv -c ak.ctx
Replace
policy.file
,ek.ctx
,ak.pub
,ak.priv
, andak.ctx
with appropriate paths. -
Configure LUKS with TPM2 Policy: Add the TPM2 policy to the LUKS volume:
cryptsetup luksAddKey --key-slot 1 --key-file= <(tpm2_unseal -c ak.ctx -p policy.file) /dev/sdXn
-
Update Initramfs: Update the initramfs to include the TPM2 tools and the LUKS key file:
update-initramfs -u
-
Configure GRUB: Configure GRUB to use the key file during boot:
nano /etc/default/grub
Add the following line:
GRUB_CMDLINE_LINUX="cryptdevice=/dev/sdXn:my_encrypted_volume root=/dev/mapper/my_encrypted_volume luks.key=/etc/luks_keyfile"
Update GRUB:
update-grub
-
Reboot: Reboot your system and test whether it boots without requiring a password.
Please note that the steps and commands provided are a general guide. You should adapt them based on the specifics of your system and the Linux distribution you are using. Ensure you understand the process and its implications before proceeding, and always have a backup of your important data.
Это похоже на реальность или всякие малинки не поддерживают TPM? И тут есть какие то жесткие уязвимости?
