2.1.1.4.1 Registration

Registration is accomplished by following the rules defined here. In addition to parsing the certificate as specified here, the transmitter MUST make sure that the receiver has been properly individualized by looking for the following string.

 <c:SecurityVersion> in <Keyfile><c:CertificateCollection><c:Certificate><c:Data>
  

If the SecurityVersion ends in ".1", the cert is individualized.

Registration MUST fail if the receiver is not individualized, as indicated by SecurityVersion.

There are multiple certificates in the CertificateCollection. Verifying the SecurityVersion data on the leaf certificate is sufficient.

The message format follows the rules documented in section 2.2.1.

See section 2.1.1.1 for Registration DRI UPnP mappings.
