What is the primary use of attestation data and logs in a TA?

• A. To verify integrity of data and logs
• B. To encrypt data in transit
• C. To speed up data transfers
• D. To identify users

Answer: (A)

Attestation data and logs are used to prove that the system and its data are in a trustworthy, untampered state. The attestation data provides cryptographic measurements of the TA’s software and configuration, creating a verifiable snapshot that a verifier can compare against a trusted baseline. The logs offer an auditable record of events that can be validated to ensure nothing has been altered after the fact. Together, they establish integrity and trust, allowing others to confirm that data and the TA’s state have not been compromised. Encryption in transit, faster transfers, or identifying users are handled by other mechanisms, not by attestation data and logs.
