TLS: Transport Layer Security. A security protocol from the IETF that is based on
the Secure Sockets Layer (SSL) 3.0 protocol developed by Netscape. TLS uses
digital certificates to authenticate the user and the network. The TLS client uses
the public key from the server to encrypt a random number and send it back to the
server. The random number, combined with additional random numbers previously
sent to each other, is used to generate a secret session key to encrypt the
subsequent message exchange.
