B. Digital signatures are intended to verify to a recipient the integrity of the data

and the identity of the sender. The digital signature standard is based on the

sender encrypting a digest of the message with their private key and the receiver

validating the message with the public key.




C. Asymmetric key cryptography always works with key pairs. Therefore, a

message encrypted with a public key could only be opened with a private key.




D. If both the sender and receiver have a private key there would be no way to

validate the digital signature.




The feature of a digital signature that ensures the sender cannot later deny

generating and sending the message is called:

C.

nonrepudiation.




D.

replay protection.

✓ :~~ You are correct, the answer is C.




A. Data integrity refers to changes in the plaintext message that would result in

the recipient failing to compute the same message hash.




B. Because only the claimed sender has the private key used to create the digital

signature, authentication ensures that the message has been sent by the claimed

sender.




C. Integrity, authentication, nonrepudiation and replay protection are all features

of a digital signature. Nonrepudiation ensures that the claimed sender cannot later

deny generating and sending the message.




D. Replay protection is a method that a recipient can use to check that the

message was not intercepted and re-sent (replayed).
