measured boot

Measured boot is a security feature that verifies the integrity of the boot process by recording measurements of firmware, boot loaders, and OS components in a Trusted Platform Module (TPM). On WindowsForum.com, discussions about measured boot often appear in the context of advanced hardware security architectures, such as Microsoft's Azure per-server HSM modules and the open-source Caliptra 2.0 root-of-trust. These implementations use measured boot as part of a layered approach to establish hardware roots of trust, enabling features like confidential computing and tenant isolation in cloud environments. The tag covers topics including TPM-based attestation, secure boot chains, and integration with post-quantum cryptography accelerators for enhanced security in enterprise and cloud infrastructure.
