Example question from this objective
Each option is explained, so the reasoning behind the distractors is part of the answer.
A company lets partner agencies digitally confirm high-value, non-refundable group reservations. Once a booking is confirmed and the price is locked, the agency must not be able to deny the confirmation later. Which cryptographic service best provides this non-repudiation requirement?
- Asymmetric Encryption for data at rest
- Message Authentication Codes (MACs)
- Symmetric Encryption
- Digital Signatures
Asymmetric Encryption for data at rest — Asymmetric encryption for data at rest helps keep stored booking information confidential. It does not provide evidence of who confirmed the booking or prevent repudiation.
Message Authentication Codes (MACs) — A MAC shows the message was generated by someone with the shared secret, but the receiver also has that key. Because either party could create it, a MAC does not provide non-repudiation.
Symmetric Encryption — Symmetric encryption keeps booking data secret, but both parties share the same key. That means it cannot prove to a third party which party created the confirmation.
Digital Signatures — A digital signature uses the sender’s private key and can be verified with the public key. This links the confirmation to the partner agency and prevents later denial of the action.
