fyi: draft XML Key Agreement Specification

[Jeff.Hodges at KingsMountain.com]

Phill sent the below msg around to a few lists back in Aug-2001. The draft 
spec he's referring to is available here..

http://www.xmltrustcenter.org/research/docs/X-KASS-31.pdf

It defines an ostensibly new cryptographic key agreement algorithm. 

Have cryptographer & security protocol designer denizens of these lists 
evaluated this stuff? Is anyone willing & able to post their 
evaluation/thoughts if so?

thanks,

JeffH

All,

	Members of the group may be interested in the attached paper that
describes a key agreement algorithm that establishes a shared secret between
two parties if an only if the two parties hold the private keys identified
in their credentials and requires only a single request/response round trip.

	I am currently working on conversion to Plaintext/RFC format,
although the diagrams loose a considerable amount when converted.

	The anticipated application area is to secure Web Services, hence
the XML syntax. However the same algorithm could be implemented in another
syntax to support other applications (IPSEC, 802.11b security, TLS).

	The paper will be available from the www.xmltrustcenter.org site in
the near future. 

	Please send comments directly to me rather than the list.

		Phill
