Measured boot is an anti-tamper mechanism. It calculates the cryptographic signatures for software system components and extends the signatures into the Trusted Platform Module (TPM) security chip. Upon startup, with the feature turned on, the Aboot bootloader and EOS calculate the hash of various system components and extend the hashes into the Platform Configuration Registers (PCRs), which is one of the resources of the Trusted Platform Module (TPM) security chip. The calculation and extension event is called the measured boot event, which is associated with a revision number to help the user identify changes to the event.

Measured boot is a tamper-detection mechanism that records a system's boot process. It calculates cryptographic hashes of system components and configurations, which are then securely stored in the Platform Configuration Registers (PCRs) of a Trusted Platform Module (TPM) chip. This process creates a secure "hash chain" of the boot sequence. After the system starts, the TPM Quote operation, along with the PCR extension records, can be used to verify the PCR values, confirming that the system components are unchanged and the software is trusted.
