Which of the following message services provides the
strongest protection that a specific action has occurred?
A. Proof of delivery
B. Nonrepudiation
C. Proof of submission
D. Message origin authentication
Answer / guest
Answer: B
Nonrepudiation services provide evidence that a specific
action occurred. Nonrepudiation services are similar to
their weaker proof counterparts (i.e., proof of submission,
proof of delivery, and message origin authentication),
however, nonrepudiation provides stronger protection because
the proof can be demonstrated to a third party. Digital
signatures are used to provide nonrepudiation. Message
origination authentication will only confirm the source of
the message and does not confirm the specific action that
has been completed.
