What is the name of the draft?

Hi List,
 
We have just submitted a draft on the use of 
Identity-Based Cryptography in CMS to this working group.
 
We are aware that there are several group working drafts 
which are dealing with Identity-Based Encryption in CMS. 
However, we think it is important to look at the use of 
IBC in CMS as a whole, including both IBE and Identity-Based 
Signature.
 
As the Signed-Data content type does not support new extensions 
as the Enveloped-Data content type, the encoding method used in 
the existing drafts, which merely focus on IBE, cannot be adopted
for IBS.
 
In our draft, we take a unified approach to deal with encoding 
both IBS and IBE in CMS.
 
Of course, there could be other encoding schemes within the current 
CMS framework. We hope this submission could initiate serious 
discussion on the use of IBC in CMS.

Kind regards,

Michael
