摘要
Disclosed herein is a method and system to determine whether a payment terminal has been tampered with based on a comparison of attestation data received from the payment terminal. If the determination yields that the request has been approved, the terminal generates an attestation ticket having one or more validity conditions, wherein the validity conditions include expiration time that indicates the time after which the attestation ticket becomes invalid. The attestation ticket can be used as long as it is valid or until another trigger causes the ticket to be invalidated or regenerated.
