Secure Sockets Layer (SSL) uses a Message Authentication Code (MAC) for what
purpose?

D. message integrity
Public Key Infrastructure (PKI) uses asymmetric key encryption between parties. The
originator encrypts information using the intended recipient's "public" key in
order to get confidentiality of the data being sent. The recipients use their own
"private" key to decrypt the information. The "Infrastructure" of this methodology
ensures that:
A. The sender and recipient have reached a mutual agreement on the encryption key
exchange that they will use.
B. The channels through which the information flows are secure.
C. The recipient's identity can be positively verified by the sender.
D. The sender of the message is the only other person with access to the recipient's
private key.
