[P1619-3] Question about using RFC3852

[Thomas Hardjono <thardjono@xxxxxxxxxxx>]

I was wondering if the 1619.3 groups has ever
discussed the possible use of CMS (RFC3852) as the
mechanism to wrap the actual keys. RFC3852 is a
well-known and widely implemented standard, and
has wide interoperability with existing PKI infra.

http://www.ietf.org/rfc/rfc3852.txt

Thus, for example, one way IEEE1619.3 could use it
is as the blob in the KeyContents:

<keyContents>
<secretContents>CMS_BLOB</secretContents>
</keyContents>

This approach would save IEEE1619.3 from having to
define its own key-wrapping syntax and having
vendors implement a new standard.

Thoughts?
