An interesting approach to vendor-independent attestation was outlined in [1]. Basically the bitstream is fed into a physical unclonable function (PUF) which is used to derive a key to decrypt the rest of the bitstream. For attestation, one could simply store the secret part of an asymmetric key in the encrypted bitstream (for challenge-response).
