Dear Jim,

all the following comments concern the H.235 white paper on the
reflector. I tried to check the remaining stuff very quickly in the
document and found the following items:

1. Page 7: goal no. 7 should end with H.235.
2. page 12: device is missing in the sentence ... not simply the physical
device.
3. page 14: Section 6.6 does not mention that MCUs as well as
intermediate GW/GKs are considered as trusted elements. Thus, the
reference in section 9.1 is misleading and should point at least to
section 3 in the appendix A instead. Why don't you include that section
also to section 6.6?
4. Page 17: Section 10.2: Headline should read Diffie-... instead of
Diffe.
5. Page 17: Section 10.2: Figure A: the request is missing the SeqNum and
should look like ... XOR randomb XOR SeqNum ...
6. page 19: Section 10.3.4: I would change exchanged to assigned in the
2nd sentence with would read then: This protocol is based on ISO 9798-3,
(5.2.1), it is assumed that an identifier and associated certificate are
assigned during subscription.
7. page 19: Section 10.3.4: The figure should allow also optional
certificate exchange.
8. Page 22: In AuthenticationMechanism one-way has to be deleted in the
comment - Diffie-Hellman.
9. certificate key protection stuff within H.245 seems not to be
complete, this needs some more inspections.....

Martin.
