Quizplus · Accepted Answer

Authentication Header (AH) provides authentication and integrity services by creating a hash-based message authentication code (HMAC) for the IP packet. However, AH does not provide confidentiality because it does not support data encryption. Internet Key Exchange (IKE) and Encapsulating Security Payload (ESP) both provide authentication, integrity, and confidentiality services as they support data encryption. BitLocker is a full-disk encryption tool, and not a network security protocol.
