Kerberos 2
Kerberos:
Kerberos is basically a network authentication protocol, it is designed for providing
authentication that is strong for the server or client by utilizing the secret key cryptography
method. Kerberos is built into all of the major operating systems that includes Apple OS X,
Windows, Linux and FreeBSD (Li et al, 2018). The Kerberos protocol has been incorporated
as an authentication method that is default in windows. This is one of the integral components
of the active type of directory services of windows. The providers of broadband service also
utilize the Kerberos for authenticating set top boxes and DOCSIS cable modems to access the
networks.
The main procedure is very much complicated as well as that can vary from one
implementation to other. For starting the Kerberos authentication procedure, the initiation
users send a request to another server for the authentication for getting access to a service
(Tbatou et al. 2017). The primary request is to be deliverd as plain text as there are no
sensitive information that are included in the request. The primary key of client can be
retrieved by the authentication server, by assuming that the user name of the initiating client
that is existed in the database of KDC. If the username of the initiating client can not be
found in the database of KDC, then the client will not be authenticated, in addition the
authentication procedure will be stop (Nath & Karforma, 2018). However, if the username of
the client might be found in the database of KDC then the authentication server may generate
a ticket granting ticket and a session key.
Advantages:
The advantages of Kerberos are as follows:
Faster authentication: A unique ticketing system is used by the Kerberos protocol which is
able to provide the authentication procedure faster.
