The Master Key - HDCP Security Vulnerability Story

A conference talk from the 38th Chaos Communication Congress (38C3) revealing the story of how researchers derived the HDCP master key in 2010 using public sources and relatively inexpensive hardware. Learn how they published this cryptographic key on Pastebin and waited to see Intel's response. The talk explains how the master key allows anyone to create source and sink keys that work with any HDCP device, effectively bypassing the content protection system. The presentation includes the actual forty-by-forty matrix of fifty-six bit hexadecimal numbers that constitutes the master key, along with instructions on how to generate source and sink keys. This security-focused talk provides insights into a significant cryptographic breakthrough that challenged a major digital rights management system.
