[dispatch] New I-D: Referencing and Validating User Attributes for SIP

Hi all,

We've just submitted an I-D which proposes a simple mechanism for 
referencing and validating user attributes in SIP communication.
You'll find the html version at 
http://tools.ietf.org/html/draft-ono-dispatch-attribute-validation-00 .

We're trying to see whether there is sufficient community interest in 
this work at DISPATCH or related WGs.

Your interest, comments, and other feedback are appreciated.

Thanks,
Kumiko

Title : Referencing and Validating User Attributes
Author(s) : Kumiko Ono Henning Schulzrinne
Filename : draft-ono-dispatch-attribute-validation-00.txt
Pages : 21
Date : 2011-10-20

This document describes a mechanism for referencing and validating
user attributes in SIP communication. User attributes, such as an
organizational affiliation and role, are helpful for the recipients
of a communication request to decide whether or not to grant the
sender access to the recipient's resources, especially when the
sender identity is unknown to the recipients. This mechanism allows
the sender to claim her attributes to recipients using an attribute
reference identifier without needing to prove the sender identity.
This document defines a new SIP "Sender-References" header field to
convey one or more attribute reference identifiers. This mechanism
satisfies all the requirements for trait-based authorization defined
in RFC 4484, except that it provides only one assertion scheme.
