Description of Working Group:
The goal of the Common Authentication Technology Working Group is to
provide strong authentication to a variety of protocol callers in a
manner which insulates those callers from the specifics of underlying
security mechanisms. By separating security implementation tasks from
the tasks of integrating security data elements into caller protocols,
those tasks can be partitioned and performed separately by
implementors with different areas of expertise. This provides
leverage for the IETF community's security-oriented resources, and
allows protocol implementors to focus on the functions their protocols
are designed to provide rather than on characteristics of security
mechanisms. CAT seeks to encourage uniformity and modularity in
security approaches, supporting the use of common techniques and
accommodating evolution of underlying technologies.
In support of these goals, the Working Group will pursue several
interrelated tasks. We will work towards agreement on a common
service interface allowing callers to invoke security services, and
towards agreement on a common authentication token format,
incorporating means to identify the mechanism type in conjunction with
which authentication data elements should be interpreted. The CAT
Working Group will also work towards agreements on suitable underlying
mechanisms to implement security functions; two candidate
architectures (Kerberos V5, based on secret-key technology and
contributed by MIT, and X.509-based public-key Distributed
Authentication Services being prepared for contribution by DEC) are
under current consideration. The CAT Working Group will consult with
other IETF working groups responsible for candidate caller protocols,
pursuing and supporting design refinements as appropriate.
Goals and Milestones:
Done Progress Internet-Draft and RFC publication of mechanism-level
documents to support independent, interoperable implementations
of CAT-supporting mechanisms.
Done Preliminary BOF session at IETF meeting, discussions with Telnet
and Network Printing Working Groups.
Done Distribute Generic Security Service Application Program
Interface (GSS-API) documentation through Internet-Draft process.
Done First IETF meeting as full Working Group: review Charter distribute
documents, and status of related implementation, integration, and
consulting liaison activities. Schedule follow-on tasks, including
documentation plan for specific CAT-supporting security mechanisms.
Oct 91 Update mechanism-independent Internet-Drafts in response to issues
raised, distribute additional mechanism-specific documentation
including Distributed Authentication Services architectural
description and terms/conditions for use of the technology documented
therein.
Nov 91 Second IETF meeting: Review distributed documents and status of
related activities, continue consulting liaisons. Discuss features
and characteristics of underlying mechanisms. Define scope and
schedule for follow-on work.
Dec 91 Submit service interface specification to to the IESG for
consideration as a Proposed Standard.
