A company would like to take electronic orders from a partner; however, they are concerned that a
non-authorized person may send an order. The legal department asks if there is a solution that
provides non-repudiation. Which of the following would meet the requirements of this scenario?

A.
Encryption

B.
Digital signatures

C.
Steganography

D.
Hashing

E.
Perfect forward secrecy

Explanation:
A digital signature is an electronic mechanism to prove that a message was sent from a specific
user (that is, it provides for non-repudiation) and that the message wasn’t changed while in transit
(it also provides integrity). Thus digital signatures will meet the stated requirements.
