If you understand the Faraday-cage example then you can't possibly believe that you're accurately characterizing my paper (let alone the holographic principle!). Let's focus on resolving the Faraday-cage dispute first.

Let me get this straight. Are you claiming that Faraday cages have a security property guaranteed by the laws of physics? If so, what precisely do you claim that this security property is?

Hi Daniel, I think it leaves an incorrect impression to say a Faraday cage merely scrambles information. They cancel EM waves, and I'm not aware of any fundamental limitation on that, especially if all you're trying to shield is which fiber-optic cable a photon travelled down. 1/

I agree that a real-world implementation will not be perfect and leak some information to a sufficiently close and sensitive detector. But for any 1-epsilon of paranoia there is a 1-delta of conductor. 2/

You focus on the holographic principle but the HP has no implications for security. It is a conjecture that a theory of gravity is mathematically equivalent to a theory on its boundary (a CFT). Your argument = if I have a quantum computer that can simulate the universe then 3/
