The application protocol transmits or receives its first byte ofĭata. To negotiate an encryption algorithm and cryptographic keys before Protocol, allows the server and client to authenticate each other and One such encapsulated protocol, the TLS Handshake The TLS Record Protocol is used for encapsulation of various higher. While another protocol is using the Record Protocol as a transport The Record ProtocolĬan operate without a MAC, but is generally only used in this mode SHA-1, etc.) are used for MAC computations. Protocol can also be used without encryption. Protocol (such as the TLS Handshake Protocol). This symmetric encryption are generated uniquely for eachĬonnection and are based on a secret negotiated by another Symmetric cryptography is used forĭata encryption (e.g., AES, RC4, etc.).

The TLS Record Protocol provides connection security that has two Transport protocol (e.g., TCP ), is the TLS Record Protocol.

At the lowest level, layered on top of some reliable The protocol isĬomposed of two layers: the TLS Record Protocol and the TLS Handshake Integrity between two communicating applications. The primary goal of the TLS protocol is to provide privacy and data Detecting Attacks Against the Handshake Protocol. Diffie-Hellman Key Exchange withĪuthentication. Avoiding Man-in-the-Middle Version Rollback. Compatibility with TLS 1.0/1.1 and SSL 3.0. Client Authentication and Key Exchange Messages. Server Authentication and Key Exchange Messages. Protocol Data Structures and Constant Values. The protocol allows client/server applications toĬommunicate in a way that is designed to prevent eavesdropping,ġ. The TLS protocol provides communications security This document specifies Version 1.2 of the Transport Layer Security Official Protocol Standards' (STD 1) for the standardization stateĪnd status of this protocol. Please refer to the current edition of the 'Internet Internet community, and requests discussion and suggestions for This document specifies an Internet standards track protocol for the The Transport Layer Security (TLS) Protocol Version 1.2 RFC 5246: The Transport Layer Security (TLS) Protocol Version 1.2
