Vocabulary

identification:

• A measurement on the object is verified against reference data.

  • Note: the reference data itself allows an attacker to artificially construct measurement data that will pass the identification test, even if the object itself it not available for the test.

authentication:

• The reference data gives insufficient information to construct a possible valid measurement data, unless a certain a known, large computational effort is invested.

enrollment :

• The object data is measured by a trusted third party, the measurements are processed and stored for later use, that is, to allow verification.

renewability:

• If the secret has been compromised: take a new one
