The correct answer involves the TLS (Transport Layer Security) protocol, which is specifically designed to provide secure communication over a computer network. TLS employs a handshake process that establishes a secure session between a client and server. This process includes the exchange of cryptographic keys and authentication information to ensure that both parties are legitimate and that the communication is encrypted. During the handshake, both parties negotiate the encryption algorithms and keys they will use for the session, thus facilitating a secure connection before any data is transmitted.

In contrast, while protocols such as PPTP (Point-to-Point Tunneling Protocol) and IPsec (Internet Protocol Security) are used for secure data transmission, they do not incorporate a handshake process in the same structured manner as TLS for authentication purposes. PPTP primarily relies on a different set of security measures that do not involve a detailed authentication handshake process, and IPsec utilizes a more complex approach focusing on securing the IP layer of a network rather than the handshake method that TLS is known for.

FTP (File Transfer Protocol), on the other hand, does not provide encryption inherently and does not incorporate an authentication handshake process like TLS. Instead, it transfers data in plaintext, making it less secure for transferring sensitive information.
