Which one of the following cryptographic goals protects against the risks posed when a device is lost or stolen?

The greatest risk when a device is lost or stolen is that sensitive data contained on the device will fall into the wrong hands. Confidentiality processes protect against this risk. Nonrepudiation is when the recipient of a message can prove the originator's identity to a third party. Authentication is a means of proving one's identity. Integrity demonstrates that information has not been modified since transmission.
