Transport Layer Security (TLS) and its predecessor, [b]Secure Sockets Layer (SSL), are cryptographic protocols [/b]that provide communications security over the Internet.[1] TLS and[b] SSL encrypt the segments of network connections above the Transport Layer, using symmetric cryptography[/b] for privacy and a keyed message authentication code for message reliability.
