Section IV: Security 553
Authentication Authentication is the process of ensuring that both the web site and the
end user are genuine. In other words, they are not imposters. Both the
server and an individual users need to be authenticated. This is
especially important when transmitting secure data over the Internet.
To verify the authenticity of a server, the server has a public and private
key. The public key is given to the user.
SSL uses certificates for authentication. A certificate binds a public key to
a server name. A certification authority (CA) issues certificates after
checking that a public key belongs to its claimed owner. There are
several agencies that are trusted to issue certificates. Individual browsers
have approved Root CAs that are built in to the browser.
