I was recently having a conversation with a collegue and he asked a question. Here goes: In OCSP, we have support the concept of a CA issuing a special certificate to an OCSP responder, allowing it to respond on its [the CA's] behalf with a special extended key usage flag. We also allow the CA to indicate that the responder's cert does not need to be validated by having it include the id-pkix-ocsp-nocheck extension in the responder's certificate. Why can't the concept of including an id-pkix-ocsp-nocheck extension in a certificate be extended to any arbitrary certificate to indicate that it doesn't need to be validated? If this makes sense, should this capability be specified in son-of-rfc2459? Comments?
