The primary goal of the TLS Protocol is to provide:

A.
Privacy and data integrity between two communicating applications

B.
Authentication and data integrity between two communicating applications

C.
Privacy and authentication between two communicating applications

D.
Privacy, authentication and data integrity between two communicating applications

Explanation:
The TLS Protocol is comprised of the TLS Record and Handshake Protocols. The TLS Record Protocol
is layered on top of a transport protocol such as TCP and provides privacy and reliability to the
communications. The privacy is implemented by encryption using symmetric key cryptography such
as DES or RC4. The secret key is generated anew for each connection; however, the Record Protocol
can be used without encryption. Integrity is provided through the use of a keyed Message
Authentication Code (MAC) using hash algorithms such as SHA or MD5. The TLS Record Protocol is
also used to encapsulate a higher-level protocol such as the TLS Handshake Protocol. This Handshake
Protocol is used by the server and client to authenticate each other. The authentication can be
accomplished using asymmetric key cryptography such as RSA or DSS. The Handshake Protocol also
sets up the encryption algorithm and cryptographic keys to enable the application protocol to
transmit and receive information.
