You either need to trust a shared server to know and then blind your identity, or trust the people with whom you share a secret key not to give that key to non-group members.
Why not use blinding for obtaining the certificate? Create a number up public/private key pairs, blind them, then do the cut-and-choose thing with the security officer. He signs the blinded key, then returns it. Unblind the remaining pubic key, and you've got a public key with the appropriate signature on it.
