It does not; the specs are published. You could design your own chip that implements them. However, the keys are embedded in the HDCP-enabled DVI/HDMI chips. If you don't sign the license agreement, you don't get officially generated, signed keys. Even if you could get a vendor to sell you chips, what keys would they contain? The vendor certainly isn't going to sell you chips containing Sony's key, for instance. Even if the vendor were to allow you to generate your own key and have chips made with it, or you made the chips yourself, they would be useless. Since your key wouldn't be signed by the HDCP licensing authority, the chips wouldn't interoperate with real HDCP products.
