'''SSL''' is the acronym for '''Secure Sockets Layer.''' It was designed to use applications that will allow users to securely send and receive data over the internet. SSL was developed by [[Netscape]] in 1994. The technology uses two protocols, the '''record protocol''' and '''handshake protocol''' to provide security between communicating applications (client and server). <ref>[http://publib.boulder.ibm.com/infocenter/iseries/v5r3/index.jsp?topic=/rzain/rzainhistory.htm IBM HIstory of SSL]</ref> The technology is integrated in web browsers e-mail and instant messaging applications and other programs with encryption key given by a Certification Authority in the form of a digital certificate. The digital key is authenticated by the handshake protocol in one or both end points during the SSL connection. The handshake protocol will then set-up a unique symmetric key to generate keys that will encrypt and decrypt data to maintain a secure communications and data transfers between computers during SSL session.<ref>[http://publib.boulder.ibm.com/infocenter/iseries/v5r3/index.jsp?topic=/rzain/rzainhistory.htm How SSL Works]</ref>

==Basic Properties of SSL Protocol Channel Security==
Based on the Internet Draft submitted by Kipp E.B. Hickman of Netscape to the [[Internet Engineering Task Force|IETF]], the SSL protocol channel security is:<ref>[http://tools.ietf.org/html/draft-hickman-netscape-ssl-00 Internet Draft-SSL Protocol]</ref>
* Private- It uses Symmetric cryptography to encrypt data and define a secret key through a simple handshake.
* Authenticated- Asymmetric cryptography always authenticate the server endpoint of conversation while the client endpoint is optionally authenticated.
* Reliable- It uses Message Authentication Code (MAC) to check the message integrity and secure hash functions.
