The TLS Record Protocol is a fundamental component of the Transport Layer Security (TLS) protocol suite, responsible for ensuring the confidentiality and integrity of data exchanged between applications over a network. It operates by fragmenting data into manageable blocks, applying compression, adding a message authentication code, encrypting the data, and finally transmitting it securely over the network.

TLS Record Protocol

Transport Layer Security (TLS) is a cryptographic protocol designed to provide secure communication over a computer network, safeguarding data integrity, confidentiality, and authenticity between client and server applications. It is widely used in securing web traffic, email, and other forms of data transmission, replacing its predecessor, Secure Sockets Layer (SSL).

A Message Authentication Code (MAC) is a cryptographic construct that ensures data integrity and authenticity by allowing verifiers to detect any alterations to the message content. It uses a secret key shared between the sender and receiver to generate a unique tag for each message, which is then used to verify that the message has not been tampered with during transmission.
