Nonrepudiation can BEST be assured by using:
A.
delivery path tracing.
B.
reverse lookup translation.
C.
out-of-hand channels.
D.
digital signatures.
Explanation:
Effective nonrepudiation requires the use of digital signatures. Reverse lookup translation involves
converting Internet Protocol (IP) addresses to usernames. Delivery path tracing shows the route
taken but does not confirm the identity of the sender. Out-of-band channels are useful when, for
confidentiality, it is necessary to break a message into two parts that are sent by different means.
