There is no security inside the HDMI cable itself. It's an HDCP negotiation between the source and the sink which occurs over an i2c serial bus along the pair of DDC pins.

You may be able to get away with just an HDMI dummy plug:

I'm not sure if these dummy plugs handle HDCP. If not you can use one in combination with this splitter:

I own this splitter and know for a fact that it handles the HDCP negotiation. But I think it needs a display attached.
