Kerberos is a protocol for verifying the identity of principals
(e.g., a workstation user or a network server) on an open network.
The Kerberos protocol provides a facility called pre-authentication.
Pre-authentication mechanisms can use this facility to extend the
Kerberos protocol and prove the identity of a principal.
This document describes a more formal model for this facility. The
model describes what state in the Kerberos request a
pre-authentication mechanism is likely to change. It also describes
how multiple pre-authentication mechanisms used in the same request
will interact.
This document also provides common tools needed by multiple
pre-authentication mechanisms. One of these tools is a secure channel
between the client and the key distribution center with a reply key
strengthening mechanism; this secure channel can be used to protect
the authentication exchange and thus eliminate offline dictionary
attacks. With these tools, it is relatively straightforward to chain
multiple authentication mechanisms, utilize a different key management
system, or support a new key agreement algorithm. [STANDARDS-TRACK]
This document is a product of the Kerberos WG Working Group of the IETF.
This is now a Proposed Standard Protocol.
