I must confess, I'm confused!
HDCP (the copyright protection mechanism in HDMI) is broken. I don't mean just a little bit broken, I mean thoroughly, comprehensively, irredeemably and very publicly broken. Broken in such a way that any possible recovery would mean layering it with so much additional new infrastructure as to render it entirely pointless. Broken. B-R-O-K-E-N.
How can I put this?
It doesn't work.
So why, then, is it still being shoved down my throat?
Why is it that if I go to iTunes to buy or rent a movie, it will tell me that my PC must support HDCP? Why does my home theatre amp need to support HDCP? Why does my HDMI switcher need to support HDCP? Why is anything on Bob's Green Earth being made with HDCP anywhere near it any more???
I'm confused.
Normally, if something is this badly broken, particularly in the security world, at least some effort will be made to replace it with something that actually works.
Take WEP for example: Broken. Replaced.
HDCP: Broken. Let's have some more! Come on in, the HDCP's lovely!
I should point out here that I'm not claiming to have anything to do with breaking it. I'm not even going to tell you about some new and interesting way of breaking it that I've discovered (although I will show you how easy it is to exploit the vulnerabilities).
What I will tell you is what I've learned about it, which, if you're like me and thoroughly confused, you may find interesting and/or useful. I know I found it hard enough to get my head around it, so maybe my little experiments in figuring out what's really going on will help someone, somewhere, to realise the jig is up and switch the damn thing off. Not likely I know, but here's hoping!
Or maybe someone will explain that I've completely misunderstood and actually it's all perfectly OK.
Whatever. For what it's worth, here it is...
So in what way is it broken?
