HDCP key protection

We are planning to use HDCP enabled adv7604, one question we have is how to protect HDCP key set so that we don't accidently leak the keys. Since HDCP keys will be pre-programmed in HDCP ROM, we want to understand if by any change that software can read HDCP keys from HDCP ROM. We don't think it is possible as adv7604 hardware should handle authentication automatically. Can anyone give us more clarification on this? thanks.
