Correct Answer should be D. Alice should Use Bryan's public key so only Brian can decrypt it with his private key. Bryan will use Alice's public key to confirm this msg came from Alice as she is the only one with the private key.

Selected Answer: D

Digital Signature Digital signature uses asymmetric cryptography to simulate the security properties of a signature in digital rather than written form.The two types of keys in public-key cryptography are the private key (only the signer knows this key and uses it to create a digital signature) and the public key (it is widely known and the relying party uses it to verify the digital signature). (P.3080/3064)
