The Secure Sockets Layer (SSL) protocol addresses the confidentiality of a message through:

A.
symmetric encryption.

B.
message authentication code.

C.
hash function.

D.
digital signature certificates.

Explanation:

SSL uses a symmetric key for message encryption. A message authentication code is used for
ensuring data integrity. Hash function is used for generating a message digest; it does not use public
key encryption for message encryption. Digital signature certificates are used by SSL for server
authentication.
