Transport Layer Security (TLS)

Abbreviation(s) and Synonym(s):

Secure Sockets Layer (SSL)
TLS

Definition(s):

  Provides privacy and data integrity between two communicating applications. It is designed to encapsulate other protocols, such as HTTP. TLS v1.0 was released in 1999, providing slight modifications to SSL 3.0.
Source(s):
NIST SP 800-95

  A security protocol providing privacy and data integrity between two communicating applications. The protocol is composed of two layers: the TLS Record Protocol and the TLS Handshake Protocol.

NIST SP 1800-21B from CNSSI 4009-2015

  Provides privacy and reliability between two communicating applications. It is designed to encapsulate other protocols, such as HTTP. SSL v3.0 was released in 1996. It has been succeeded by IETF's TLS.

NIST SP 800-63-3 under Secure Sockets Layer (SSL)

  An authentication and security protocol widely implemented in browsers and web servers. TLS is defined by RFC 5246. TLS is similar to the older SSL protocol, and TLS 1.0 is effectively SSL version 3.1. NIST SP 800-52, Guidelines for the Selection and Use of Transport Layer Security (TLS) Implementations, specifies how TLS is to be used in government applications.

  An authentication and security protocol that is widely implemented in browsers and web servers. TLS is defined by RFC 5246 and RFC 8446. TLS is similar to the older Secure Sockets Layer (SSL) protocol, and TLS 1.0 is effectively SSL version 3.1. [NIST SP 800-52] specifies how TLS is to be used in government applications.
