A new edition of the Kerberos V5 specification "The Kerberos Network Authentication Service (V5)" . This version obsoletes RFC 1510, clarifies aspects of the protocol and intended use in a more detailed and clearer explanation.
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.
V5.1 only supports the Control, PSTN and ISDN protocols. V5.2 also supports BCC, Link Control and Protection protocols. V5 layer 3 protocols are transported on a layer 2 protocol called LAPV5, a variation of the LAP-D or Link Access Procedures, D channel ISDN transport layer. V5 is a protocol stack which controls circuit-switched communication ...

This protocol aims to establish a session key between two parties on a network, typically to protect further communication. The Needham–Schroeder Public-Key Protocol, based on public-key cryptography. This protocol is intended to provide mutual authentication between two parties communicating on a network, but in its proposed form is insecure.
Microsoft has added the NTLM hash to its implementation of the Kerberos protocol to improve interoperability (in particular, the RC4-HMAC encryption type). According to an independent researcher, this design decision allows Domain Controllers to be tricked into issuing an attacker with a Kerberos ticket if the NTLM hash is known. [20]
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 ...
Kerberized Internet Negotiation of Keys (KINK) is a protocol defined in RFC 4430 used to set up an IPsec security association (SA), similar to Internet Key Exchange (IKE), utilizing the Kerberos protocol to allow trusted third parties to handle authentication of peers and management of security policies in a centralized fashion.
