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.
