PureBoot is Purism’s cutting edge, complete secured boot process and combines a number of technologies including:
Neutralized and Disabled Intel Management Engine where only the code absolutely essential for the system to boot is left in the ME.
Coreboot the free software BIOS replacement.
A Trusted Platform Module (TPM) chip
Heads our tamper-evident boot software that loads from within coreboot and uses the TPM and the user’s own GPG keys to detect tampering within the BIOS, kernel, and GRUB config.
Integration between the Librem Key and LUKS disk encryption so you can unlock your disk with your Librem Key.
