What's the exact difference between secure boot and device attestation. Nowadays with secure devices both are used, even at the same time, when in the core they do similar things, which is verification of the software running on the platform.

    Secure Boot is a specific UEFI technology from Microsoft, whereas attestation is a general technique done by extending PCRs in TPM hardware to verify the state of firmware, bootloader, etc. Not an answer because this is such a brief explanation. – forest Nov 30 '18 at 8:05
