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]
This issue exists for Kerberos systems as well, where failure to retrieve a current authentication token will prevent system access. An alternative to using CRLs is the certificate validation protocol known as Online Certificate Status Protocol (OCSP).
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.
If the Kerberos provider is functional and a Kerberos ticket can be obtained for the target, and any associated settings permit Kerberos authentication to occur (e.g. Intranet sites settings in Internet Explorer), the Kerberos 5 protocol will be attempted. Otherwise NTLMSSP authentication is attempted. Similarly, if Kerberos authentication is ...
Security Support Provider Interface (SSPI) is a component of Windows API that performs security-related operations such as authentication.. SSPI functions as a common interface to several Security Support Providers (SSPs): [1] A Security Support Provider is a dynamic-link library (DLL) that makes one or more security packages available to apps.

HMAC was approved in 2002 as FIPS 198, The Keyed-Hash Message Authentication Code (HMAC), CMAC was released in 2005 under SP800-38B, Recommendation for Block Cipher Modes of Operation: The CMAC Mode for Authentication, and GMAC was formalized in 2007 under SP800-38D, Recommendation for Block Cipher Modes of Operation: Galois/Counter Mode (GCM ...
