  ITU-T A.5 justification information for referenced document IETF RFC 3881 (2001) in draft H.810
1. Clear description of the referenced document:
Name: IETF RFC 3881 (2001)
Title: Password-based Encryption for CMS
2. Status of approval:
Standards track RFC approved December 2001. Obsoleted by RFC 3369, RFC 3370.
3. Justification for the specific reference:
ITU-T H.810 requires the use of this obsolete RFC, Password-based Encryption for CMS, for the encryption of data using user-supplied passords over the WAN Interface. This document provides a method of encrypting data using user-supplied passwords and, by extension, any form of variable-length keying material which is not necessarily an algorithm-specific fixed-format key. The Cryptographic Message Syntax data format does not currently contain any provisions for password-based data encryption and H.810 requires this within its architecture. Further, there is dependency on the use of this RFC across other IHE and HL7 that also use this version of the protocol in this protocol, and there are many H.810-compliant WAN devices certified by Continua Health Alliance.
4. Current information, if any, about IPR issues:
N/A.
5. Other useful information describing the "Quality" of the document:
Proposed Standard RFC approved December 2001. Obsoleted by RFC 3369, RFC 3370.
6. The degree of stability or maturity of the document:
See 5. above.
7. Relationship with other existing or emerging documents:
N/A.

9. Qualification of ISOC/IETF:
9.1-9.6     Decisions of ITU Council to admit ISOC to participate in the work of the Sector (June 1995 and June 1996).
9.7     The Internet Engineering Steering Group (IESG) is responsible for ongoing maintenance of the RFCs when the need arises. Comments on RFCs and corresponding changes are accommodated through the existing standardization process.
9.8     Each revision of a given RFC has a different RFC number, so no confusion is possible. All RFCs always remain available on-line. An index of RFCs and their status may be found in the IETF archives at http://www.rfc-editor.org/rfc.html.
