WebTCP header structure. TCP wraps each data packet with a header containing 10 mandatory fields totaling 20 bytes (or octets). Each header holds information about the connection and the current data being sent. The 10 TCP header fields are as follows: Source port – The sending device’s port. Destination port – The receiving device’s port. WebThe Transport Layer Security (TLS) protocol adds a layer of security on top of the TCP/IP transport protocols. TLS uses both symmetric encryption and public key encryption for securely sending private data, and adds additional security features, such as authentication and message tampering detection. in Internet communications.
