<br><font size=2 face="sans-serif">So, would something like the following
be of use?</font>
<br>
<br>
<br><font size=2 face="sans-serif">Device with device certificate and key
pair. (Same for SHV)</font>
<br>
<br><font size=2 face="sans-serif">Device also has certificate of SHV.
(and vise versa)</font>
<br>
<br><font size=2 face="sans-serif">CertificationState = Hash(all required
HCD attributes)</font>
<br>
<br><font size=2 face="sans-serif">CertificationStatement = CurrentDataTime
+ CertificationState </font>
<br>
<br><font size=2 face="sans-serif">CertificationIntegrity = Sign(CertificationStatement,
Device[PrivKey])</font>
<br>
<br><font size=2 face="sans-serif">HCD_CertificationState = Encrypt(CertificationIntegrity,
SHV[PubKey])</font>
<br>
<br>
<br><font size=2 face="sans-serif">Just wondering ...</font>
