I can't believe people are willing to assign any credibility to an anonymous dump of hex to pastebin.

That's the wonderful thing about math. You can verify its correctness without reference to anybody's reputation or personal opinion. Indeed, that's pretty much the definition of math.

  Of course you can verify if it's valid, but that's remarkably short of what's being claimed here. Lots of folks here are talking as if this is the end of HDTV DRM. I'm simply advocating that someone with the means actually test it before we start singing "Ding Dong The Witch is Dead."

Catch-22. Credibility is less because it was posted anonymously as a dump of hex to paste-bin, therefore eliminating any authority that would come if this person was a well-known security researcher. If the author had credibility and wanted to use his/her reputation to make the post more credible, he'd have the pleasure of a herd of lawyers and law enforcement at his door, assuming that he lives in a country with anti-circumvention laws. So his only choice is to keep it to himself or post anonymously, taking away any credibility that comes with authority in a subject. Regardless, someone will test this soon enough and determine if this non-credible post is credible or just a creative bunch of social engineering. That it's garnered this much attention this quickly (take a look at your major social news sites ... and tech blogs) should scare industry insiders. The mere HOPE that some random posting on pastebin would topple HDCP and bring a possible end to device interoperability would get this much attention truly highlights what a dismal mess HDCP is. If it's The Real Thing(tm), we'll know when the master key is used to generate a random device key and 80% of the time the signal is decrypted properly without having to turn both devices off and back on. And if it is true, I hope our friend that posted it took some pretty serious precautions to protect his own anonymity.
