![]() ![]() ![]() The IETF officially took over the SSL protocol to standardize it with an open process and released version 3.1 of SSL in 1999 as TLS 1.0. These are the basic working principle of TLS. Also for each message ends client and server gets a certificate of authentication and finish the handshake process, This session ID will be saved for future use so that This TLS session can be resumed in the future. This multi-step process is a little complex that the record protocol, in TLS, a server provides an identity to the client by the use of public and private key pairs, Then the session key has been generated and shared between client and server, then the main part is establishing a secure session by using TLS, In this client and server exchanges the simple hello messages with encryption keys. Authentication of the server and optionally, the client.When establishing a secure session, the Handshake Protocol manages the following: Transport handshake Protocol is a multi-step process, Handshake Protocol is responsible for the authentication and key exchange necessary to establish or resume secure sessions. When the Record Protocol is complete, the outgoing encrypted data is passed down to the Transmission Control Protocol (TCP) layer for transport. Encrypting outgoing messages and decrypting incoming messages.Applying a Message Authentication Code(MAC) to outgoing messages, and verifying incoming messages using the MAC.Compressing outgoing blocks and decompressing incoming blocks (optional). ![]() Dividing outgoing messages into manageable blocks and reassembling incoming messages.The Record Protocol is responsible for securing application data and verifying its integrity and origin. In these TLS record protocols Secures the application data using the keys created during the Handshake. 1.The TLS record protocol–> provides connection security.Ģ.The TLS handshake protocol–> Enables the client and server to authenticate each other and to negotiate security keys before any data is transmitted. ![]()
