So, would something like the following be of use?


Device with device certificate and key pair.  (Same for SHV)

Device also has certificate of SHV.  (and vise versa)

CertificationState = Hash(all required HCD attributes)

CertificationStatement = CurrentDataTime + CertificationState 

CertificationIntegrity = Sign(CertificationStatement, Device[PrivKey])

HCD_CertificationState = Encrypt(CertificationIntegrity, SHV[PubKey])


Just wondering ...
