Connection establishment and Termination in Transmission Control Protocol (TCP) need not Encrypt the connection established message.
The Transmission Control Protocol (TCP) is one of the main protocols of the Internet protocol suite. It originated in the initial network implementation in which it complemented the Internet Protocol (IP). Therefore, the entire suite is commonly referred to as TCP/IP. TCP provides reliable, ordered, and error-checked delivery of a stream of octets (bytes) between applications running on hosts communicating via an IP network.
Connection
establishment:-
To
establish a connection, TCP uses a three-way handshake. Before a client
attempts to connect with a server, the server must first bind to and listen at
a port to open it up for connections: this is called a passive open.
Connection
termination:-
The connection termination phase uses a four-way handshake, with each side of
the connection terminating independently. When an endpoint wishes to stop its
half of the connection, it transmits a FIN packet, which the other end
acknowledges with an ACK. Therefore, a typical tear-down requires a pair of FIN
and ACK segments from each TCP endpoint. After both FIN/ACK exchanges are
concluded, the side which sent the first FIN before receiving one waits for a
timeout before finally closing the connection, during which time the local port
is unavailable for new connections; this prevents confusion due to delayed
packets being delivered during subsequent connections.
