A manufacturer has been purchasing materials and supplies
for its business through an e-commerce application. Which of
the following should this manufacturer rely on to prove that
the transactions were actually made?
A. Reputation
B. Authentication
C. Encryption
D. Nonrepudiation
Answer / guest
Answer: D
Nonrepudiation may ensure that a transaction is enforceable.
It involves creating proof of the origin or delivery of data
to protect the sender against false denial by the recipient
of the data's receipt, or vice versa. Choice A is incorrect
because the company's reputation would not, of itself, prove
a deal was made via the Internet. Choice B is not correct as
authentication controls are necessary to establish the
identification of all parties to a communication. Choice C
is incorrect since encryption may protect the data
transmitted over the Internet, but may not prove that the
transactions were made.
