I have reviewed this document as part of the security directorate's
ongoing effort to review all IETF documents being processed by the
IESG.  These comments were written primarily for the benefit of the
security area directors.  Document editors and WG chairs should treat
these comments just like any other last call comments.

The only big  issue I see is that the draft uses a different key derivation
than the simplified profile in RFC 3961.   What is the reason for this? 
Assuming there is a suitable reason for this I think the draft is ready to go
with some minor issues.

1. I think in section 3 random2key should be random-to-key as in section 4.
2. It would be good to reference section 6 for random-to-key and RFC 3961 for
k-truncate as well. 3. Section 6 does not provide an entry for "string-to-key
parameter format" 4. The encryption and decryption description in section 6
seems a little incomplete.  In particular the setting of newstate seems to be
missing in the encryption.  In the decryption perhaps you should define how
newIV is determined.

Cheers,

Joe
