Answer Options
A
Authentication
B
Authorization
C
Integrity
D
Nonrepudiation
Correct Answer: D

Nonrepudiation allows a recipient to prove to a third party that a message came from a purported source. Authentication would provide proof to Fotis that the sender was authentic, but Fotis would not be able to prove this to a third party.
