Editing Authentication protocol (section)

====[[Kerberos (protocol)]]====
Kerberos is a centralized network authentication system developed at [[MIT]] and available as a free implementation from MIT but also in many commercial products. It is the default authentication method in [[Windows 2000]] and later. The authentication process itself is much more complicated than in the previous protocols - Kerberos uses [[symmetric key cryptography]], requires a [[trusted third party]] and can use [[public-key cryptography]] during certain phases of authentication if need be.<ref>{{cite web|url = http://web.mit.edu/kerberos/|title = Kerberos: The Network Authentication Protocol|date = 10 September 2015|access-date = 31 October 2015|website = web.mit.edu|publisher = MIT Kerberos}}</ref><ref>{{Cite book|title = Applied Cryptography|last = Schneier|first = Bruce|publisher = John Wiley & Sons, Inc.|year = 1997|isbn = 0-471-12845-7|location = New York|pages = 52–74}}</ref><ref>{{cite web|url = http://srp.stanford.edu/history.html|title = Protocols of the Past|access-date = 31 October 2015|website = srp.stanford.edu|publisher = Stanford University}}</ref>
