Security Certificate
A way to confirm automatically that a public key 
is correct (is really the one that's used by a particular entity) in order to prevent man-in-the-middle attacks. Most often used by websites to prove to your browser that you have a secure connection to the real site, and not to some other system that's tampering with your connection.
