SSL – Secure Socket Layer TLS – Transport Layer Security Both provide a secure transport connection between applications (e Service-point addressing To protect our users and networked systems, the support and use of encrypted communications using TLS is mandatory for all systems Transport-layer security is provided by the transport mechanisms used to transmit information over the wire between clients and providers, thus transport-layer security relies on secure HTTP transport (HTTPS) using Secure Sockets Layer (SSL) The protocols define the mechanisms to ensure secure transmission of data over the internet However since it does implement session identity, integrity, start up, tear down and management it very much belongs in the session layer The OSI Model has seven layers: Layer 1 - Physical Layer 2 - Data Link network-layer protocol = postal Transport Layer Security is used within organizations that use payment processes, store sensitive data such as medical information, or

Thereafter, any mechanism that relies on the master … Layer Security Towards a new era of secure messaging Benjamin Beurdouche, Katriel Cohn-Gordon, Raphael Robert BlackHat USA 2019, Las Vegas, CA g TLS was derived from a security protocol called Secure Socket Layer (SSL) 10 In transport layer, message is divided into transmittable The main use of TLS is to encrypt the communication between web applications and servers, like web browsers loading a website - Transport Layer Security (TLS) is an encryption protocol used to protect email messages between sender and recipient, preventing eavesdroppers from reading your messages The upper layers, the Application Layer, Presentation Layer, and Session Layer, are responsible for preparing and sending the raw data Session layer This layer
