Dan recently received a digitally signed message and when he attempted to verify the digital signature received an error that the hash values did not match. What can Dan conclude from this error?
A. The message was altered by a malicious individual after being sent.
B. The message was accidentally corrupted in transit.
C. There was an error creating the digital signature.
D. Dan can’t draw one of these specific conclusions.
Correct Answer: D
Any one of these scenarios is a plausible reason that the digital signature would not verify. Dan cannot draw a specific conclusion other than that the message he received is not the message that was sent by the originator.
