Verification path

Security and digital identity

Is key validity separate from identity assurance and current trust?

Ask in this order

  1. Is the file structurally valid?
  2. Does its exact state match the protected hash?
  3. Is any signature mathematically valid?
  4. Is the key trusted and its real-world identity actually verified?
  5. Is time independently trusted?
  6. Is the document or key still current?
