Kerberos (krb-wg) ----------------- Charter Last Modified: 2007-11-12 Current Status: Active Working Group Chair(s): Jeffrey Hutzelman Larry Zhu Security Area Director(s): Tim Polk Sam Hartman Security Area Advisor: Sam Hartman Mailing Lists: General Discussion:ietf-krb-wg@lists.anl.gov To Subscribe: https://lists.anl.gov/mailman/listinfo/ietf-krb-wg Archive: https://lists.anl.gov/pipermail/ietf-krb-wg/ Description of Working Group: Kerberos over the years has been ported to virtually every operating system. There are at least two open source versions, with numerous commercial versions based on these and other proprietary implementations. Kerberos evolution has continued over the years, and interoperability has been problematic. A number of draft proposals have been issued concerning aspects of new or extended functionality. The group will strive to improve the interoperability of these systems while improving security. Specifically, the Working Group will: * Clarify and amplify the Kerberos specification (RFC 1510) to make sure interoperability problems encountered in the past that occurred because of unclear specifications do not happen again. The output of this process should be suitable for Draft Standard status. * Select from existing proposals on new or extended functionality those that will add significant value while improving interoperability and security, and publish these as one or more Proposed Standards. Goals and Milestones: Done First meeting Done Submit the Kerberos Extensions document to the IESG for consideration as a Proposed standard. Done Complete first draft of Pre-auth Framework Done Complete first draft of Extensions Done Submit K5-GSS-V2 document to IESG for consideration as a Proposed Standard Done Last Call on OCSP for PKINIT Done Consensus on direction for Change/Set password Done PKINIT to IESG Done Enctype Negotiation to IESG Done Last Call on PKINIT ECC Done TCP Extensibility to IESG Jul 2007 Set/Change Password to IESG Jul 2007 Naming Constraints to IESG Done ECC for PKINIT to IESG Aug 2007 Anonymity to IESG Aug 2007 Hash agility for GSS-KRB5 to IESG Aug 2007 Hash agility for PKINIT to IESG Aug 2007 Choose direction for Kerberos v5.3 Sep 2007 WGLC on preauth framework Nov 2007 WGLC on OTP Nov 2007 WGLC on hardware preauth Dec 2007 WGLC on data model Dec 2007 WGLC on cross-realm issues Jan 2008 WGLC on STARTTLS Jan 2008 WGLC on Referrals Mar 2008 WGLC on Kerberos v5.3 Mar 2008 WGLC on IAKERB Mar 2008 WGLC on LDAP schema Internet-Drafts: Posted Revised I-D Title ------ ------- -------------------------------------------- May 2003 Sep 2007 Kerberos Set/Change Key/Password Protocol Version 2 Sep 2005 Oct 2007 ECC Support for PKINIT Jun 2006 Jan 2008 Anonymity Support for Kerberos Jun 2006 Oct 2007 Additional Kerberos Naming Constraints Nov 2006 Nov 2007 Kerberos Version 5 GSS-API Channel Binding Hash Agility Oct 2007 Dec 2007 Problem statement on the cross-realm operation of Kerberos Oct 2007 Jan 2008 OTP Preauthentication Oct 2007 Oct 2007 Initial and Pass Through Authentication Using Kerberos V5 and the GSS- API (IAKERB) Dec 2007 Dec 2007 An information model for Kerberos version 5 Request For Comments: RFC Stat Published Title ------- -- ----------- ------------------------------------ RFC3962Standard Feb 2005 AES Encryption for Kerberos 5 RFC3961Standard Feb 2005 Encryption and Checksum Specifications for Kerberos 5 RFC4120Standard Jul 2005 The Kerberos Network Authentication Service (V5) RFC4121Standard Jul 2005 The Kerberos Version 5 Generic Security Service Application Program Interface (GSS-API) Mechanism: Version 2 RFC4537 PS Jun 2006 Kerberos Cryptosystem Negotiation Extension RFC4557 PS Jun 2006 Online Certificate Status Protocol (OCSP) Support for Public Key Cryptography for Initial Authentication in Kerberos (PKINIT) RFC4556 PS Jun 2006 Public Key Cryptography for Initial Authentication in Kerberos (PKINIT) RFC5021 PS Aug 2007 Extended Kerberos Version 5 Key Distribution Center (KDC) Exchanges Over TCP
