Kerberos (/ ˈ k ɜːr b ər ɒ s /) is a computer-network authentication protocol that works on the basis of tickets to allow nodes communicating over a non-secure network to prove their identity to one another in a secure manner.
an NT LAN Manager authentication mechanism GS2-family of mechanisms supports arbitrary GSS-API mechanisms in SASL. [3] It is now standardized as RFC 5801. GSSAPI for Kerberos V5 authentication via the GSSAPI. GSSAPI offers a data-security layer. BROWSERID-AES128 for Mozilla Persona authentication [4] EAP-AES128 for GSS EAP authentication [5]
Works with Kerberos (e.g. Active Directory) and other authentication mechanisms to map different identities and hence allow single signon to all IBM server platforms (Windows, Linux, PowerLinux, IBM i, i5/OS, OS/400, AIX) even when the user name differs.
Integrated Windows Authentication (IWA) [1] is a term associated with Microsoft products that refers to the SPNEGO, Kerberos, and NTLMSSP authentication protocols with respect to SSPI functionality introduced with Microsoft Windows 2000 and included with later Windows NT-based operating systems.
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.

Key /Config-authentication is used to solve the problem of authenticating the keys of a person (say "person A") that some other person ("person B") is talking to or trying to talk to. In other words, it is the process of assuring that the key of "person A", held by "person B", does in fact belong to "person A" and vice versa.
